Have a Sanyo Plasma TV DP50747 and both picture and sound all of a suden went. I turned it on from the remote and the green power light goes on, but no picture or sound and the power light goes off again...

Hello,

Yep. The power supply in Sanyo Plasmas are generally prone to failures. It could be a failure in the panel not priming, but I doubt it. Turn the lights off in the room, then try to turn it on. If you see the screen faintly flash, the panel is priming, but it is not coming on. If the screen is lit, but is still "black," then it is a control or digital board. If it is totally black with no light at all, then it doesn't entirely rule out the first two, but makes a power supply failure more likely.

They usually have a lot of heat damage to them. If you have tried unplugging it for 15 minutes, then plugging it back in and it still doesn't work, the it is most likely a secondary in the power supply.

I hope this helps you...

Tv wont power up makes a noise but no picture

Your power transformer is likely shot. It'll cost at least $200 to have it replaced. Someone can come to your house to diagnose it. Usually costs around $65.
