Hello, I am a new member with a problem with my WS-65611 tv. Read alot of the treads and tested for codes. Code is 21 after pushing menu and device buttons for the 5 seconds. The tv will stay on and get a good picture after unplugging overnite for about 5 minutes and then shuts itself off. Hitting the front panel power button will turn on tv but it immediately turns off. By the way, Downloaded service manual from another site as I could only get front 2 pages from yours after multiple tries and I see others have same trouble. I am not a professional tv man but am 68 and can fix almost anything and read the manuals,lol.

I have the blinking green light and have fixed it 3 times now, but this time it does not seem to reset. Any ideas other than the caps?
