SOURCE: No picture, just sound
No new video card required. I just reset the television by holding the on/off button for five seconds (yellow light on front panel blinks repeatedly). I then cycled power using the remote control and my picture came back. Worked for me. Hope it works for you.

I had the same problem last night - sound but no picture form any of the inputs - DVD, VCR, FIOS or antenna. I could still see the TV menu. If you go to the TV menu - you can go to the settings (far right top), from there you can choose to restore factory settings, usually needs a code - 0000 (if you did not choose a different one), select yes when prompted if you want to restore factory defaults. This brought my picture back. I lost all of my picture preferences i had set - but at least I got a picture! I hope this helps!!

There is an issue with the audio processor. Most likely it is the main board needs to be replaced in order to fix the issue. You will need to remove the back cover in order to get access to it.
There could also be an issue with the power supply supplying the right voltage to the processor. This can be checked by seeing if the 18V DC is present at pins 3 and 4 of CN90 on the power supply. If the voltage is present, then replace the main board. If it is not, replace the power supply.
