SOURCE: Have a Sanyo Plasma TV

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...

You tv used lamp XL-2400 or also known as F93087500. It is very common for this bulb to fail and have the exact symptom you are experiencing. I cant count how many times I have seen it.. Replace the lamp with either the exact Sony or an OEM and you will be back in business..
Good Luck!!

TV Picture Goes Black


I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions
