Sounds like an inverter problem. On some of these sets, the inverter and the power supply are on the same board. These boards tend to be quite pricey, $100 + range. I've worked on your particular model with the same problem, and it was a bad inverter/power supply board. I would recommend you get a diagnosis to be sure.

If the tv is not getting power besides warning lights, No pic or Sound, then most likely your power supply will need to be replaced.

No,this is the internal hard ware power supply problem

power supply not working -- did you check internal fuses on board --? if everything checks alright - replace the power supply board

it probably blew the power transformer

I replaced the flyback transformer and horizontal output transistor and works great.

your problem is likely to be in horizontal section of tv. please take the help of skilled tech. it is not a major problem but as you know that it is a high voltage device.
