Everything completely shuts down. Audio/video-everything.

Okay. Approximately how many minutes does it take to turn on? What is the color of the power LED after TV turns off autommatically?
Customer: replied 7 years ago.

When I turn the set on for the first time on any day it takes only a few seconds to come on; maybe 3-5sec. After it shuts itself off it takes maybe 7-10 seconds.

Okay. You mean the power flickers? What is the color of the power LED after TV turns off autommatically?
Customer: replied 7 years ago.
The powder does not flicker. The set shuts down and the red and green LED lights flash for a few second then stop. When I turn the set back on the the LEDs flash again and the screen stays drak for 7-10 seconds.

I wish I had a "press-a-button" fix for this. The problem seems to be with the over heated power supply. There might be bad or burnt components such capacitors or rectifiers or fuse. Most of the times there are swollen caps which need replacement. The bad components are a result of heat or cold solders etc. The next thing that needs to be checked is the lamp door. It me not be closed properly. I'd like you to check this. If you want to repair it yourself then you should be having proper knowledge about the internal circuitry of the TV.
You should also require a multimeter and soldering equipments and schematics.
If you wish to take it to a repair shop would you like to have an idea of the cost of repair?
If you have any other queries then I would be glad to assist you further.

Regards.
