Question about Sanyo DP50747 50 in. Plasma TV
Was watching unit and suddenly powered off. I unplugged unit and plugged it back in. It came back on for a while , then did the same thing a couple of days later. Now units power light will come on after unplugging but no picture or sound.

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...

Tries tv unplug,replug it back like about an hour later.The tv should resetting itself back to the factory setting.Now,the tv should be working again.If tv have the same result,the tv power supply board is the causes and the problems.That the board,where the power a/c cord plug into it.Try website like Ebay.com to buy a refurbish power supply board for the replacement.

this issue is related to either the y sustainer and z sustainer boards, checking the fuses on the y/b will giving you a good indication, if they are open(bad) then you'll have a easy fix, if not, i would try replacing the y board first.
