Question about Toshiba TW65G80 TV
i have a Toshiba TW65G80,when i turn on unit it clicks like always but no picture or sound and power lite stays on,when i turn unit off u can see screen flash.if i unplug it for30 minutes or so and pug it back into wall it clicks2 times then 2 more times and power lite flashes and if i press the screen size button i can see the power lite stay on for 2 or 3 sec and goes back to flashing.if i unpug it again and turn it on it goes back to solid power light and nothing else.i found a serv manual onlinr i bought and was wondering if any ideas on what it might be.i seen a few answers for other problems so im assuming it has to do with unit not getting full power to some parts.
thx if u can help point me in direction of whaqt to look at.

SOURCE: Picture goes black
GO TO MENU, THEN SETUP, SCROLL DOWN TO TIMER AND MAKE SURE IT IS ON 0 (ZERO) MIN. SOUNDS LIKE ITS PROGRAMMED TO GO SLEEPAFTER A CERTAIN TIME. THIS TV ALSO CUTS OFF AUTOMATICALLY IN 15 MIN. IF ITS TUNED TO A VACANT CHANNEL( NO PICTURE).

Same problem with mine. Relays click, sound, no picture and a flashing power LED. I finally found a schematic online. I went through the high voltage circuits and found the power transistor 2SC5570 was shorted out. There is also a pico fuse in that area but my was not open. I replaced the transistor and prayed the flyback transformer was not shorted. It wasn't, I'm watching my old 36" right now. Not a bad fix (17.00) bucks. Wonder what a service tech would have charged ;)
