In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary

does it happen on the any input or just on tv setting?
if it's judt tv then sounds like the tuner, if it's on any input, then the video chip or a decoder on that board.

When the tv goes to a black screen does the sound remain on? Also,if you listen carefully can you hear any arcing noises in the back of the tv?

means you prolly have something wrong in the tv with the actual board or chip in your tv. im not fimiliar with your model but i have a panasonic viera and it wouldnt tuen on shortly after and they said i had to send it in for repair

Anyone have issues with the HDMI input on this TV no longer functioning?
