SOURCE: TV Shuts Off randomly

Our flat panel TV would shut off for 5 to 10 seconds and then come back on. We found out that our Comcast HD box was bad. After a tech replaced the bad box with a good box the problem went away.

About every other time I turn on my LT 52149 TV there is no sound. The picture is fine, but no sound. Usually if I turn off my Verizon Fios STB (HD QIP 71001) and the TV together and then turn them both...

This is a tough one without seeing it. The audio is located on the main board. If you determine that it is not a problem w/ the hdmi cable, such as it not being secure to the tv and other device, then a new main board should fix the problem as long as it's not a problem w/ the the device that it is coming from. Have you tried another device w/ an hdmi cable to see if it still does it?
