If you are getting the initial 'pang'(!!!???) noise, then it looks like a cold solder in the Horizonbtal Oscillator or Hor. Output stages. The set is trying to power up, but the Horizontal Oscilator is not 'booting' up. Since it is a new set, it must be under warranty....Get it checked by the company Technician.

Does my grundig tv model g2412 fledv support mpeg 4? I only get sound and no picture for the new free to air channels.

Free-to-air, or DTV, is Mpeg 2 and is supported. Mpeg 4 is supported for playback via files on external storage connected via the USB port.
Try doing a Restore to Defaults via the on-screen-menu in case there is a bad setting somewhere.

I have a Grundig XENTIA 82 FLAT MFW 82-430/8 TV, everytime i turn it on i get a blue screen & the child lock nb to fill in, so i have to type the nb 7038580 to watch tv... how can i cancel this koz...

If this is happening on all the channels I think you will need a total reset. If so open menu and check the settings for child lock when you manually tune. An option is to reset the channels once again after the lock is opened. Choose a new channel scan to reset the memory. However if the lock seems to be only on specified channels you can open the settings of the channel and unlock on the menu.

Grundig s350, installed new batteries and radio keeps shutting off by itself

When you press the Power/Sleep button the radio turns on and displays a number 90, or some other numbers. This is the play time that the radio will stay on then turns itself off. It could be that yours is configured with a sleep timer set to 01 minute, 10 or 15. You need to set the timer for a longer period. Thus we turn it on by pressing the Power/Sleep button, read the timer length then press again. Keep making short presses: The timer will cycle through all preset sleep timer durations. Select the length you want.

Grundig Satellit 800 LCD display doesn't work correctly

If the radio uses memory batteries, try changing these with new alkalines. The microprocessor needs this power to drive the display.

Grundig TV - Colours all mixed - still have fullpicture

Hi rosscop

You have a magnetic interference problem. First, have you put any magnetic objects like speakers near the set recently. They will cause this. Turn the set off at the wall and wait for 15 mins for the PTC device that turns on the degauss coil to cool and operate. It is the loud burst of hum you here when you turn the set on from cold.

0083efa.jpgThe PTC is a postive tempeture coefficient that allows alot of current to flow at first, heating up as it does, and then slowly less current as it heats. This is why you need to turn the set off and let it cool. If the problem remains The PTC may be faulty allowing too much current to flow and upsetting the magnetic flux about the tube. If you dont have the skills you will need a technician to sort it out for you.

There is probably a fault in the video processor, or there is a setting for the user colour temperature that is not properly set. Call the authorized service for advice on how to proceed.
