    Hello. I have the same problem. I was watching tv with my 19 month old daughter and the screen suddenly had all the color distorted and you couldn't see the picture. I thought it was my digital cable getting a bad signal. I turned everything off, when I turned it back on the screen was black & no sound. I tried changing the changels and nothing happens. There is no movement for volume or video chanels. HELP !!!!!! I don't have money to buy a new tv I have a 19 month old HELP PLEASE!!!!!

    I have a blank screen but I do have sound. I have heard this can be fixed with a main board..? Can someone be more specific? or should I hunt for a part called a main board for this tv.



    thanks in advance

I had the same problem and Sanyo does not make parts for this model anymore. Luckily I had the extended warrantee so they reimbursed the full purchase price.

Weird that the poster above mine was able to get a part; I was told the part is no longer available.

If you want it fixed, you'll have to take it to a real tech. If you read this garbage you'll probably end up spending more that the tv is worthed in the long run to fix it.

Sanyo plasma tv screen is black and theres no sound, but the green light is on.

No sound and no video is usually means the main board is bad. Green power indicated power supply might be OK.

Plasma Hyundai 42'' TV ,NO SOUND OR PICTURE

most times then not it's the capacitors on your power board that blew there for not supplying the tv with enough power if you open it up and check the capacitors it should be leaking some kind of liquid or the tops have bubbled up. its an easy fix cost>>2 dollars each

Samsung plasma all black screen

Black Screen come from three areas. 1- Power Supply Board 2- Inverter Board 3- Processing Board on the LCD. Since the Power Supply Board was replace, it easy to troubleshoot where the problem. lies If you cannot get the backlight, then its the inverter board. If you can use a flash light on the TV screen and can barely see the images, then the problem is indeed the inverter board. If you cannot see any images when using a flash light, then the problem comes from the LCD processing board. Let me know if you have any success. Mike

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...
