Same thing happened to me


Well, no sound no picture = power supply unit
Sound no picture= flyback
picture no sound =tuner/audio logic

You get my drift?

You power supply is bad you replace it you got another new TV, with this digital conversion hitting I would rather advise you to get a nice flat panel and donate that one to Goodwill

Power problems problem on


I would try a power drain:  Unplug the TV's power cable so the TV is not grounded to the house.  Then press and hold in the TV's own power button for one minute to drain the capacitors. Plug the TV back in and see what happens.  If the TV will still not turn on, I would say you have a problem with the TV's mainboard as a dead power supply will not light any LED's for you.

No power no picture no sound


You have a shorted power component. Probably either the voltage regulator or the Horiz. output transistor. Both will be mounted to a heat siink of some type. The Horiz. power circuits along with the flyback transformer power up 90% of most TV sets.
