Hi.

Using AV entry ensure that the red/white leads have been connected properly to TV Audio input. SCART is supposed to have built in sound. Test using a different scart.
Try disconnecting power cord for fifteen minutes, that will discharge internal component and reset the TV. Double check audio settings just in case.

If all that does not help, then the problem is likely the sound circuit inside TV. In this case the audio circuit is built-in the main board. Usually with the 19'' LCD TVs you need to replace the main board. Parts for this model are not available from third party distributors. In case the TV is defective, I suggest calling the Grundig number listed on your owners manual to arrange repair or to check part availability. To find contacts you can also use the 'International' tab on top of this page:Welcome to Grundig.

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!
Thanks for using Fixya.

Hmm
Looks like the back light or the driver circuit has failed.
If you shine a bright torch at the screen can you see a very faint image ?
If so then its the back light has gone.
If you cant see anything its the screen driver.
