If you are using a hdmi cable take it off and switch to component cables if the problem goes away keep it that way. Sometimes the hdmi hookups have bugs like this.

i know your problem. its an inverter loose connection from CCFL to inverter output. back of your LCD inside the TV. try to remove and re-connect again. be sure no power and AC is unplugged. [email protected]
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.

Holding the power button down for 10 seconds fixed this problem on my Regza 47"
SOURCE: Was watching tv( Toshiba Regza)and the screen went blank.
I have the same television and ocasionally the sound shuts-off, but I still have a picture.
What type of cable system do you have? What kind of converter box? I am trying to find out if it is the TV or converter box. I change the channel a couple of times and the sound usually comes back.

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!!
