Try changing the input device to some other. Look for any loose contacts in RC jacks/sockets/Cable. Check and ensure that the color system selected like PAL/Secam etc. is matching. Try changing the detection of color system to auto mode.

LCD and PLASMA sets do not use them---LCD rear projection sets that have a lamp for the light source use them: light from lamp shines into the engine and picture with color emerges from lens at top of optical engine, it shines into a mirror which projects it on the front screen---Display is LCD but with a mirror it is also rear projection.

I think I know what the problem is. I have the same tv and been going through the same thing. Looking in the manual it says you need to get sound through the pc audio its the green audio jack. you have to get a female Y analog to pc cable. I saw one on ebay for $2. My problem is I've also got my computer hooked up.

You can use the RCA cables to the input of the LCD TV so that the HD can be viewed. If HDMI is available it can be used to connect. The cable line must be connected to the box.

Hi, Make sure there is nothing between you and the remote to turn it on. Check battery in remote
Good luck.

You may have dying power supply or bad solder joints that go bad when heated up.
See example here:
