My HDMI input stopped working a few days ago. I took the Sony 350 Blue Ray in and had it and the cable checked, no problem. I tried the Blue Ray software upgrade, unplugged and reconnected the cables, still no go. If I have the TV on and then trun on the Blue Ray, I'll see a glimpse of the Blue Ray menu, and the the screen just goes blank.
Any ideas?
Thanks,
Jason
The problem is the main board in your TV. If your TV is a LG or SONY brand, please try this:
Re-Flow Soldering Procedure for LG Main Board
1.Pre-heat your kitchen oven to 385 degree (No more than 400 degree);
2.Put the main board on a card board (like a pizza box board) in the oven;
3.Heat it for 10 minutes (No more than 10 minutes);
4.Turn the oven off & leave the door open, at this moment, do not touch or move the board until it colds down to the room temperature.
5.Install the board in the TV & try it out.

i had the same problem and the only way i could solve it was to disconnect power from the tv, let it "reset" then it would be ok for a bit. the problem went away entirely when the cable company updated its software for its hd box. might be coincidence....
also, pre-update, the resolution wouldnt automatically set correctly. If I turned on the tv to a hi def station, it would set to 480 and only set to 1080 when i changed to a normal station then back to the hd. then it was fine. again, after the update from the cable company this went away.

You say this doesn't happen on regular cable or when playing a regular DVD. Hmm. Is this Blu-Ray player connected by simplink? HDMI is a bi-directional format cable, so there are cases in setups where your tv can send commands to your blu-ray player and vice versa. It could be a problem with your blu-ray player that it is sending for some odd reason a mute command to your tv. Or is processing a command that your TV interprets to be a mute command when playing blu-rays. Because if it was the TV itself chances are you'd see this when watching a normal DVD or on cable as well. Since you say you're not, it leads me to believe the issue lies with the blu-ray player itself.

It sounds like your LCD Screen is no longer working. I would try contacting Sony and ask for a refund. I had the same T.V and the LCD Screen had gone out. A techniction came out and Condemned the screen and i had to pay $500 for a new T.V.
