Hi.
If the flicker is given by backlight, then the problem is either inverter board or power adapter. In some case a defective PC board may also be responsible. A defective inverter is the part that gives this problem more commonly.
Parts for most models can be purchased online entering model number in one of the websites below:
ShopJimmy
PartStore
Here a summary description showing how to test inverter and PSU.
Parts must be tested before replacement. The job must be done by a trained technician.
Call Grundig to check warranty status or to get a quote on repair.

Hi Mike,
Power on the unit in the dark room then shine with the flashlight directly in
the screen, you will barely see the images. This is because your backlight is
not functioning. The following reason is the caused.
1. Power supply - missing
B+(supply voltage) coming from this board feeding the inverter board. This is
caused by faulty transistor, dried/leaky electrolytic capacitor, open fusible
resistor.
2. Inverter board - even
the B+ is good from the power supply, if the fuse, driver transistor, driver transformer
is faulty no output to the backlight resulting to black picture.
3. Busted backlight - even
inverter board is good but if this is busted resulting to black picture also.
Diagnosing the fault is technical and if you don't have necessary tools and test instrument and can't fix it yourself, I would
advice you to look for an experienced
technician to isolate the
problem.
Hope I helped you.
Have a nice day!
