Plug it in, here a relay. See a green LED shining (showing me that it is in standby) on the front panel. Push power and nothing happens. Replaced Horizontal Output Transistor. Still no change. Replaced a zillion caps. Still no change. Any ideas? Can you help me? You seem to be very serious about repairs...anything specific for this model as far as notorious components going bad? PLEASE HELP or point me to someone who can! Thanks in advance.

Sounds like one of the front panel buttons is jammed. press each one and see if any fail to "rebound" or feel different from the rest. You can usually work the button in a 'circular motion" to release it. If the buttons seem normal , it's possible that the switch inside the TV has collapsed
the green led actually means its out of standby.advance the a 1 control to see if you have field collapse.dry jonts on the regulator ics is a common problem too....steve.ps.if the crt heaters are lit ,the psu and line stage is functional...
Sounds pretty bad to me, I had a computer monitor that did a similar thing when plugged in after blowing, it's not a good thing. I didn't even bother to mess with it. You may have to replace the whole power board or at least have a whole handful of pieces to re-solder. It most likely isn't worth it unless your other tv's are under 30" and you don't have a lot of money ;)
if the tv set have no sound no picture, they call it dead set your tv need a repairman technician to trace your tv what was part was damage. but if your tv has standby mode mybe you entered the timer code.
