I'm having the same problem with mine but it will come back on after a while of clicking away...
You plug it in and i may only click once or twice, then come one, or it may click for 10min and come on. Then once its on it may turn off in an hour and start clicking again, or it may stay on all night. Once it turns of and starts clicking, it eventually comes back on and the cycle repeats.
Was this the same symptoms yours had? I tested the transistors and unless i tested wrong they appear to be good, but then again the tv still works *sometimes* so idk what it could be.
I tested a few of the caps that i thought could be the culprit although none of them look bulged at all.
Anyone have any ideas here? Can transistors be half bad and not just good/bad?
Thanks!
