I have a Westinghouse SK-26H640G HDTV. The set has several symptons. It powers on and off by it self. It jumps from the input menu to the main menu, and it jumps into and through various menu options and sometimes makes adjustment on it own. I am at a loss at what is wrong or how to fix it. Anyone have any ideas?

I don't know if this will work for everyone, but we were having much the same problem with our Westinghouse LCD TV (which is what led me to this site in the first place.) After a great deal of experimentation we have found that if we keep the backlight setting at 3 or lower we do not have the problem. If we try to view it on the level 4, 5 or 6 setting the picture goes crazy after 5-15 minutes and does not clear up until the set has been turned off for about 30 minutes. Good luck! I hope this works for you too.

The same thing was happening to mine and the problem was in the power supply. Apparently, there was a loose connection causing it to go in and out. The round connector end that plugs into the monitor has two prongs on the inside. I was able to bend each prong toward the center with a thumb tack so that it would have a tighter connection, and it now works fine. Unplug from wall before working on the prongs.

This problem is caused from a problem with the main board. The main board will need to be replaced. It runs from $100.00 to $150.00.
