Does the guarantee also cover Grundig products imported individually from abroad to the Czech Republic?
|
|
Maintenance servicing for the whole assortment of the Grundig consumer electronics is provided on
the territory of the Czech Republic regardless of where a product was purchased. However, a claim
for a free of charge guarantee repair can currently only be applied with goods imported
to the Czech Republic through Grundig Ceska Republika s.r.o. or Fast CR, a.s. Please ask the
vendor from whom you bought your product for information about the conditions of your guarantee.
|
|
I bought a universal remote control for a product that you service, but in the accompanying list
of codes supported by the remote, this product (brand) is missing. Could you please give me the code?
|
We are sorry, but we do not know the combination that the manufacturer of the universal remote control
assigned your product, and therefore cannot give it to you. Ask the vendor from whom you bought the unoriginal
remote, and if he is unable to provide you with the code, cancel the purchase contract. In case of interest,
we can provide you with an original remote control, which belongs
to the product and which is not normally much more expensive than a universal remote, with a 100% guarantee
on all functions.
|
|
Where can I get operating manuals for Grundig products?
|
According to Section 9 (1) of the Consumer Protection Code, a vendor has the duty to properly inform
a purchaser of a new product about the characteristics and manner of use and maintenance of the product,
as well as the danger arising from its improper use or maintenance. If it is necessary owing to the nature
of the product or the manner or duration of its use, the seller has the duty to provide that this information
be contained in appended written instructions that are understandable. According to Section 11 of the Code,
all written information must be in Czech.
However, the lack of a Czech instruction manual is not a defect which
could be grounds for a claim. In case this happens, you can inform the Czech commercial inspection organ,
which is authorized to impose a sanction for this delict. You can also demand a Czech instruction manual from
the vendor on the basis of Section 617 of the Civil Code.
If you are looking for an operating manual for your Grundig device, you will find it on the
official Grundig homepage.

The image of DVB-T channels from one multiplex on my new television sometimes stops with mosaic and sound dropped out.
The other channels are in order. I have tried another receiver, which works perfectly. Can a new television have low
sensitivity or some other defect?
|
|
Normally, several DVB-T multiplexes are broadcast from one transmitter on different channels with the same power output.
It does not mean, however, that the level and quality of the signals will always be the same in all multiplexes at the
receiving end. If on top of that, signals broadcast on the same frequency from different transmitters (SFN) meet, and in
big cities with different polarization on top of that, even a negligible difference in the path of the wave, a movement
of the antenna or an obstacle can be enough for one or more multiplexes to have significantly different characteristics
than others. Besides the level, in DVB-T the quality of the signal defined particularly by CBER (the error rate before
the Viterbi correction) parameters, VBER (the error rate after the Viterbi correction) and MER (the modulation error ratio)
are significant. For quality DVB-T reception it is necessary for the signal to be stable and have a level above 40 dBµV,
a CBER lower than 1.0*E-2, a VBER lower than 1.0*E-6 and a MER higher than 24 dB. By properly choosing the location, moving
the antenna on its vertical axis or winding it toward its sides, it is often possible to very significantly improve
the reception of the signal. If another receiver works without problems at a given place, it still does not mean that your
television has a defect or low sensitivity. It is important what parameters the signal from your antenna has and whether
the problem also occurs in places where the quality of the signal is checked, such as a shop or service centre. If the antenna
has been checked by a professional company, it is essential when lodging a claim to provide the values this company has measured.
You can usually display informative facts (information about the signal) alone on the television. If these values are under 70%,
it is not possible to guarantee quality reception any more. In such a case, don't look for the problem in the television, but
have the antenna checked by a professional company, which is equipped with professional measuring technology.

I have a problem with my TV. When tuning it to digital channels, it is not possible to automatically change the assigned
pre-selection channel numbers (for example CT1 to 1, CT2 to 2, Nova to 3, etc.). I can only change the order of the channels
in the table, but the numbers stays the same. Is there a procedure for changing the numbers? With analogue
channels this works, but not with digital channels. I haven't found anything about this in the instructions. Can you please
advise me what to do?
|
|
This problem is connected with the LCN (Logical Channel Number) function, which is part of the DVB standard. Digitally
transmitted channels can have it entered by means of an LCN descriptor in what fixed order they are to be saved in a given
region (CA TV). In such a case, individual re-numbering by the user cannot be allowed, because duplicities could arise
during the new tuning or adding of a new program. Television and distribution companies which participate in digital
broadcasting in our country do not use this service. Thus, receivers with the LCN function firmly assign numbers in
accordance with SID (identification of digital service - Service ID). This is a specific problem given by the momentary
state of digital broadcasting in the Czech Republic, which can be usually solved by recording new firmware,
in which the LCN function is turned off for the Czech Republic.

How is it possible that after two years of using my TV set, there are vertical lines on the display in places
bordering a 4:3 picture?
|
Unlike classic CRT tubes, flat displays (plasma and LCD) are more responsive to the permanent displaying
of a static crisp image. With regards to this, one can talk about a kind of memory that the display has
of a static picture. This memory is either short-term (reversible), or irreversible - when a static image
displayed long-term stays on the faceplate, apparently permanently. The most dangerous case of long-term
viewing of a picture in a 4:3 or 14:9 format is when on a wide-angle display, vertical black lines appear
on the sides. The same damage to the display can be caused by long-term use of computer games or by using
the television set as a monitor in camera systems, for displaying information texts or for repeating commercial
spots, especially at a high-contrast setting. It is generally thought that this problem concerns only
plasma displays; however, irreversible changes can also happen to LCDs. Unlike plasma displays, in which
a permanent reductions of emissions (exhaustion) of luminescent material often occurs, in LCDs this
phenomenon is caused by a "fatigue" of the liquid crystals. It manifests itself as darker vertical
lines or spots on the transitional plane of a 4:3 picture and is usually more obvious on the right side
of the display. During normal use with full-surface imaging (for 4:3 broadcasting choose the AUTO or
PANORAMA mode), the troublesome background often disappears alone over time. This physical phenomenon is
given by the level of the LCD technology and it cannot be considered to be a defect. Also, the legal
guarantee does not extend to such wear. For reducing this undesirable effect, different electronic circuits
exist which automatically move the standing image so that it does not stay in one place, but their effect
should not be overestimated. However, similar darker lines or spots on LC displays can have a completely
different cause: under the influence of the electrostatic charge, dust can settle on the ground glass
plate, the reflector and the lamps of the backlight of the display, especially in a smoky environment.
In such a case, it is enough to have the display professionally cleaned in an
authorized service centre.
As the display is the most expensive part of the television set, in every case we recommend that you allow
an expert to assess the spots on the image.

|
For some time, I have not been able to adjust the volume across its whole range;
at the same time, the pre-programming of the TV set cannot be changed. Why?
|
Apparently the so-called hotel mode was activated in the receiver. This feature is part of a service
setting and is thus not accessible to the user. An authorized
service centre will perform the de-blocking. This is not considered to be a guarantee repair but
a paid service.
|
|
Out of negligence, I have blocked my TV set with the children's lock and I don't know the code.
Could you explain to me how I can unlock it again?
|
The procedure for unlocking the TV set without knowing the safety code is normally to be found in
the operating manual. If you do not have access to the manual or cannot find the procedure for
unlocking the TV set in it, or if your attempt at unlocking has failed, please refer your problem to an
authorized service, which will un-block your set.
This is a paid service that the guarantee does
not apply to.
|
|
During use my television sometimes turns off and on again. I took my claim to an authorized service centre,
but even after a long-term trial they did not find any defect. Why?
|
|
In order for a repair to be successful, the claimed defect must somehow appear at the service centre. Therefore,
when logging a claim, the purchaser must be aware of his legal obligation to prove the defect or the fact that
is contrary to the purchase contract. If therefore you do not manage to describe the defect in such a way that
it would be possible to unambiguously evoke it, or if the defect does not appear in the service centre, there
is no sense in insisting on a repair or pointing at the incompetence of the service centre. If at your home,
your television repeatedly turns off automatically and a similar defect does not occur in a repair shop,
a possible cause could be your home electricity distribution. It happens very often that some connections
in distribution boards, wiring boxes, switches or outlets are not properly finished. Especially older wiring
with aluminium conductors requires regular checking of all screw joints. A great transition resistance of such
an imperfect joint can cause a short-term fall in voltage or a complete outage of the power. The power source
protection in the TV then reacts by turning it off. You can check this in the simplest way by, for example,
plugging a table lamp into the same outlet as you use for the television (the light bulb flashes the moment
the receiver is turned off) or by plugging the receiver into a different outlet circuit (the problem disappears).
If you have a sufficiently laid out backup source used for computers (UPS), you can connect it as a test.
|
|
My TV set does not show some of the characters of the teletext correctly. Why?
|
This defect can have several causes:
- The error occurs accidentally. Some characters are missing or will repair themselves
after a while. This is caused by a poor television signal or by bad tuning of the receiver.
You will find a suitable test on page 899 of the CT1 or CT2 teletext.
- Only characters with Czech signs are incorrectly displayed. In this case, check the selection
of the character set of the teletext (see operating instructions). Usually the incorrect setting
is "Western Europe" or "Turkey". All TV sets imported to the Czech Republic
by Grundig enable this selection and some of them even separately for each program preset.
If the TV set was imported individually from abroad, then it may only be fitted with the western
character set. In such cases, we will be glad to find out whether the decoder can be replaced
and at what price.
- The defect occurs only when the so-called fly-pages are displayed for a long time
(e.g. page 100 on CT1 or 101 on TV Nova and Prima TV), where part of the content is cyclically
overwritten. This problem is caused by the incompatibility of some teletext decoders and should
be removed by a software adjustment on the transmitting side. To check this, you may use
page 897 on CT1, TV Nova or Prima TV.
|
|
From time to time, static electricity crackling is heard from the rear part of the TV set. Is this a defect?
|
|
The static electricity discharges in the surroundings of the tube are a natural phenomenon accompanying
high voltage changes (e.g. switching the TV set on or off, switching between programmes and quick luminance
changes). It occurs in particular in connection with tubes with a larger diagonal and depends, among other
things, on the relative humidity of the air. As nowadays, the rears of TV sets are made of thin plastic
with many ventilation holes, the crackling can, as a matter of fact, be distinctively heard in a quiet room.
But this is no defect. In case of doubts we recommend making a comparison with another TV set of the same
type or similar design.
|
|
What is the cause of colour areas on the screen?
|
- If the spots are of permanent nature and you have not observed them earlier, this is probably
caused by magnetization of the mask of the screen. Every TV set is equipped with a demagnetisation
circuit, which briefly activates on turning on the power supply switch. If you only turn off
the device to standby mode (by remote control), then switch it off for 1 hour by means of the main
switch and you can turn it on again (if necessary, repeat several times). If this procedure improves
the problem only partly, then the screen must be demagnetised by a special demagnetising coil
at the service station. To avoid this defect, make sure that there are no sources of magnetic field
near your receiver (speakers, transformers, metal objects). To prevent this problem, we recommend
turning off the TV set with the main switch at least once every two weeks.
- If spots appear only when contrasting scenes are displayed for a longer time and then disappear,
then you might have a CRT with a steel mask (e.g. "Black Line D"), which is used in some TV
sets because of its favourable price. On a prolonged display of contrast transitions or bright areas
(= high cathode current), the mask of the screen can be unevenly heated, causing its reversible
heat deformation ("doming"). As a result of this, colour spots, which again disappear
after a change in the picture may temporarily appear. The colour temperature may fluctuate by
up to T = 2000 °K in such cases. According to the manufacturer, this is not a defect but
a generally known physical quality of these cathode ray tubes given by their design and price.
In TV sets with screens, which use the invar mask, this effect does not occur. However, the use
of such screens increases the price of the device.
|
|
While watching television in a quiet room, it is possible to hear an unpleasant whirring coming
from the back of the set. How is it possible that my older television set did not suffer from this?
|
|
The cabinet of modern television sets are made of thin plastic and have many vent holes on the back wall.
Therefore, they do not have the same sound suppressing ability as the boxes of older sets. In the case
of sets with a classic CRT screens, the noise is normally a magnetostrictive hum exiting the deflection coils.
In 100 Hz CRT sets, this hum is even more evident, because the frequency (200 Hz) is double that of classic
50 Hz receivers and the human ear are more sensitive in this field. This phenomenon cannot normally be
considered a defect as it is given by the construction of the set. In television sets with an LCD
or PDP display, the whirring may come from a transformer in the supply circuits. You can easily find
out whether your concrete case is a defect or a characteristic given by the construction by comparing your
television with another set of the same type.
|
|
Why do a longitudinal white line on the top edge of the picture and white dots on the bottom edge
appear when the 4:3 TV set is switched to a 16:9 format?
|
|
The reduction of the vertical dimension of the picture makes 3 measuring lines (red, green and blue)
visible on its top edge and the data of the teletext, VPS and VITC flash on the bottom edge.
At 4:3 display ratio, these parts of the picture are overlaid by the mask of the screen.
The measuring lines are generated by the video processor of the TV set and are necessary for the automatic
setting of the cut-off currents of the screen and thereby also of the colour black. The teletext,
VPS and VITC dates are keyed into the video signal by the transmitter. This phenomenon cannot be
considered to be a defect.
|
|
Why do white or coloured spots sometimes appear on the screen after switching off the TV set and
then gradually disappear?
|
|
Thanks to impregnated cathodes with a reinforced emission layer, modern CRTs boast great contrast,
brightness and sharpness. Because of the great thickness of the emission layer and resulting heat
lag of the cathode, the emission of electrons ceases more slowly than with older types of CRTs
(cold emission). Low-end TV set categories are not equipped with a switch-off circuit (Black Switch Off).
The residual high voltage discharge of the tube then attracts the electron cloud to the screen,
thus causing the said effects. This effect has no impact on the function, technical parameters or life
of the set. The occurrence of the said phenomenon is not a reason for a guarantee complaint, nor can it
be considered to be a defect.
|
|
On replay via AV input the picture is only black and white. Why?
|
|
The parameters of the external input of the TV set are probably not correctly set (instead of the FBAS/CVBS
composite signal, the S-Video composite signal has erroneously been selected). Check the AV inputs setting
in the control menu. Also, an interconnection error between devices or an unsuitable cable cannot be
excluded as the cause of this.
|
|
|
Why does my VCR sometimes fail to record the pre-set programme?
|
|
No method or function for automatic programming of records (VPS, Show View, VPT, Megalogic…) can eliminate accidental
errors. Sometimes, the setting is bad; sometimes, the time or date on the VCR is wrongly set. Also, a printing error with
the Show View code or an incorrectly transmitted or missing VPS signal cannot be excluded. With some models, a power
supply outage causes erasure of the timer. So far, however, we have not met any hardware defect in a VCR causing this problem.
|
|
A family member was playing and blocked our Grundig VCR. Does a trick exist (such as a universal password), to put the
VCR into operation, except for a visit to a service centre?
|
In order to unblock a lock, it is usually necessary to delete the memory, which also contains the service setting of the VCR.
It is necessary to renew this setting for the proper function of the device. Therefore, we recommend that you allow an
authorized service centre to handle this task.
|
|
|
There are picture, sound or subtitle outages with some disks and some disks cannot be played at all. Why?
|
|
A turbulent development is taking place in the field of DVD technology. If we rule out a hardware defect (for instance a defective
DVD drive), then this is usually caused by an older version of the firmware of the DVD player, which does not support some new
functions, formats or authoring of the disk. We recommend an inspection at the service section, which requires handing over the
disk when this defect demonstrably occurs.
|
|
Why can I not play some original CDs or CD-DA disks with copy protection on my DVD player?
|
|
Some types of protection (e.g. Cactus Data Shield) go so far in their principle that the disks become unreadable not only for PC
drives but also for some CD and DVD players. This is not a malfunction of these devices but rather a case of non-observance
of the CD-DA (Red Book) specification standard. These disks are defective and you can file a complaint at your vendor's shop.
|
|
Is it possible to modify an older DVD player to view digital JPEG photos burned onto a CD?
|
|
If the DVD player does not support direct viewing of JPEGs, there is a simple solution: when burning a CD, choose a VCD or SVCD
compilation instead of the CD-ROM format. It will be just as possible to burn JPEGs as if they were MPEG files. The result will be
an image gallery ( slideshow) in which you can also create a menu with thumbnails. For burning we recommend the Nero Ahead program.
|
|
Can I play DVD disks in NTSC in colour and without jitter on a television that has only the PAL standard?
|
|
It is very deceptive to talk about NTSC, PAL or SECAM standards in connection with digital CD, DVD or cassette (DV) recordings. These
are systems for analogue TV recording or transmission. In the digital form, the difference in these signals is only in the resolution
and the frequency of frames. Unfortunately, on discs, in instruction manuals, in many popular handbooks and sometimes even in professional
literature, PAL, SECAM or NTSC are still incorrectly used for the purpose of simplification. The PAL analogue signal has a 720 x 576
resolution and a 50 Hz frame frequency after conversion to digital form. In NTSC, the respective values are 720 x 480 / 60 Hz. In each
DVD player it is possible to set whether all DVD discs are to be reproduced in the PAL system (SECAM is not used), in NTSC, or whether
the original format should be left (&MULTI& or &AUTO& setting). If therefore the original recording was digitalized in NTSC as
720 x 480 / 60 Hz and you have the DVD player set to PAL, the player will re-sample the signal to 720 x 576 / 50 Hz and on its RGB or
YUV (YPbPr) outlets a signal with this resolution and frame frequency will appear. In these signal components there is no PAL/NTSC/SECAM
coding, unlike FBAS (CVBS) and S-VIDEO outlets, where in this case, the signal will be coded in the PAL system.
Correct solution: If your receiver supports a 60 Hz frame frequency (it does not need to be able to decode NTSC), it is enough
to set the &MULTI / AUTO& mode on the DVD player and join the devices with an RGB or YUV (YPbPr) signal.
Emergency solution: If you have a receiver which in the aforementioned case has problems with the vertical synchronization
of the picture (it cannot handle a frame frequency of 60 Hz), set it to the &PAL& play mode and connect the devices with an RGB,
YUV (YPbPr), FBAS (CVBS) or S-VIDEO signal. In such a case, however, the aforementioned problem with &twitching& or "jitter"
of the image caused by converting the frames from 60 to 50 Hz will occur.
Erroneous solution: On the DVD player you have &NTSC& or &MULTI / AUTO& set up and the television is connected to an FBAS (CVBS)
or S-VIDEO outlet. In a better case, you will get only a black and white picture when playing American standard discs recorded
through a television which doesn't have an NTSC decoder. If on top of that, such a television does not support a 60 Hz frame
frequency, it will not be possible to watch the picture at all, because it will be vertically non-synchronous.

When connecting an MP3/WMA player to the USB port of a computer with Windows XP, although the new external memory device is properly
detected, no such device appears in the &My Computer& display. Is this a set-up error or do I have to install some control device?
|
|
The Windows XP operating system normally does not need any new control devices for communication through a USB interface. The
aforementioned problem has a different cause, which is related to connecting further network units (disks). Namely, if the first
free letter after those assigned to local memory devices (FDD, HDD and CD-ROM) is momentarily taken by one of these network units
(typically E or F), the system does not consider the unit's letter to be taken and also assigns it to the newly connected USB device.
The result of this conflict is that although the network disk still works correctly, the USB device is not available. You can
easily avoid this operating system error by permanently assigning a different letter to the USB unit:
1. Temporarily disconnect all network disks.
2. Connect the player to the USB interface. In a while, it should already appear as another disk in the &My Computer& display.
3. In the selection Start -> Control Panel -> Administrative Tools -> Computer Management choose the item Disk Management.
4. Find the disk of the player (it will be marked as a removable medium) and with the right button on the mouse choose &Change Letter
of Drive and Path&.
5. Change the letter of this unit to another, which you don't use (we recommend B, for example), and confirm with the OK button.
6. Renew the connection of network disks on original positions.

My MP3/WMA player shows up as an MTP Media Player in the &My Computer& display after connecting to the USB port of the computer
and the icon of the player with the GRUNDIG symbol appears in the display. I would like my player to appear as an external disk
(Mass Storage Device). Is there a way of changing this?
|
|
For transferring files between a player and a PC, we recommend using the MSC (Mass Storage Controller) protocol. If the player
determines that Windows Media Player 10 or higher is installed on your computer, it will preferentially choose the MTP
(Media Transfer Protocol) protocol. Switching between MTP and MSC modes is carried out by pressing the MODE button on the player
for roughly 4 seconds (the player must be connected to the PC). The current mode of communication with the PC will be shown
on the display of the player (whether the MTP sign is shining or not).

Do you know the reason why my radio alarm clock does not show the correct time? The RDS synchronization is turned on (&CT ON&),
in order for the time to be automatically adjusted when the radio is turned on. Whenever the updating ends, the time is not set
correctly. Is it necessary to take the clock for repair?
|
|
If your RDS time synchronization is activated, the time and date are set whenever the radio is turned on according to the RDS
data being broadcast at that time by the radio station it is currently tuned to. Unfortunately, this information can be inaccurate
in some stations and some don't even broadcast it. It is thus not a flaw of the alarm clock, but an error in the RDS data of
the radio station concerned. The simplest solution is to manually adjust the time on the alarm clock or to allow
the synchronization to come from a station that sends correct RDS time (for example, LR1), and turn off automatic synchronization
(&CT OFF&). The clock will then work on the frequency of the mains, which is normally fully adequate.

|
Who can I turn to with a request to find out the security code of a Grundig car radio?
|
If you submit an ownership document of a receiver (or a car), we may obtain the code from the central records based on the serial
number for you. The device must be handed over or sent to our service centre to verify the code and the serial number. The price
of this service is set in our price list.
If an unauthorized service centre offers a similar service, please note that a new code &cloned& from another device will be recorded
onto the receiver for about the same price. The entire protection will thus lose its reason of being as you will obtain the same code
as other customers of that service centre. Moreover, this newly assigned code can never be detected as it does not correspond with
the serial number of the receiver.
|
|
Why do the batteries discharge relatively quickly in a portable radio with a digital tuner or a CD player?
|
- The power consumption of processor-controlled devices may be up to 100% higher than in simple analogue
receivers. This is balanced by a higher convenience of operation (display, memory, clock).
- The average power drain of motors of scanning units in today's portable CD players does not exceed
0.5 W. Usually, these devices are equipped with an &Anti-shock& (DAS) function with buffer storage which
(if active) raises the power drain roughly by 0.15 W. During normal use, the total power drain
of the device does not exceed 0.8 W (!), which, however, represents an energy take-off of up to
250 mA under a supply potential of 3 V. This current can double when searching for tunes, at higher
volume or mechanical upheavals. If regular batteries (LR6/AM3/E91/AA) have a capacity of, for example,
1000 mAh, their discharge can already come after 4 hours. The information about the maximum playing
time given in the technical specifications of the product is valid under ideal circumstances,
i.e. playing in a calm environment (on a flat plane), without searching and added functions (DAS,
UBS etc.), with zero volume and when using &Long Life& batteries with a capacity of up to 2000 mAh.
Discharge of batteries is understandably unpleasant owing to their price, but no servicing can change this.
Therefore, for lowering the cost of operation, we recommend that you always use rechargeable batteries
(NiCd, NiMH).

Whom should I address when my satellite receiver cannot be controlled and only the key symbol is shown on the screen?
|
The electronic safety lock (children's lock) was activated. The operating instructions will instruct you how to deactivate
the function. If you have the instructions or don't know how to do it, turn to an
authorized service station,
which will unblock your receiver. The guarantee does not apply to unblocking; it is
a paid service.
