    My plasma did the same thing but the little green light stays on, repair estimated at 650.00. My set was 15mo. old so, I paid 100.00/mo. to watch it.............

    I have a 42 inch sanyo plasma tv that stopped working on me in middle of a movie. It shut itself off then when i tried to turn it back on the green light came on and it clicked like it was turning on but no picture. The green light stays on but a picture or sound never did.

    In the middle of watching a show and it shut off. I tried to turn it back on and nothing showed on screen. The lower green power light turns on and off yet the same problem exsists.

    Okay, it sure looks like a common problem is happening here. I have an 18 month old DP42746 and the other day, my kids were watching tv and all of a sudden, the screen went black and the sound died. Upon turning it back on, the relay on the back clicked on for a few seconds then turned off again. Now I've got a 1500.00 black mirror. From what I've read so far, the Y-main is probably gone (probably a diode or transistor) and possibly the lower buffer board. I've bypassed protect mode and now I only get sound out of the video out modes. LED is flashing 12 times indicating a D12V problem. Anyone know where I can purchase these circuit boards or even have them repaired?

    Pissed off in Toronto.....

    i too have a sanyo plasma and the screen went out the same. light blinking 12 times. it took 2 months for the service man to come to repair it, from 100's of miles away, mind you i live in the valey of california. anyway, after replacing the main circuit board, it now comes on for a few seconds to maybe a minute each time with the light blinking 13 times now indication says its a "time over". now what the heck does THAT mean?

    i am calling for them to just replace this thing. apparently its a chronic problem....

    any comments?

I am a military spouse and our same tv did the same thing on Super Bowl Sunday 2009! We did everything we know to do: call the company, called the repair man, etc. There apparently isn't a solution to this that wouldn't cost more than the tv is worth. So I got an attorney to start a class action:

Mine did the same thing a month ago. I just finished paying it off in Feb 09, so I called around to a few places to see if they can fix it.. Some places wanted anywhere from 75-200 dollars just too look at it, and Geek Squad with Best Buy want to charge $100 an hour after that $200 look at it fee to fix it. But I had to find and buy the parts. WTF.??

I called the place I bought it from and was told that they could take to a repair shop that they use to get it fixed and I could pay what they pay. Long story short...

My TV had 4 fried circuit boards that had to be replaced.It took a month for them to fix it... but it was worth it , because all I paid was $435.00.

Before I sent it off.. I did some research.. and noticed we all had the same problem.. which is the Y circuit boards and main power supply.. I would call around for the cheapest price for a repair man who specializes in Plasmas... make sure that the parts and labor is included in the price.

The message: input: hdmi Front keeps showing up in the upper right hand corner of the tv.


Try selecting your input one at a time. What happened is you choose the hdmi as your input but at the back of the tv you connected your input wires (to maybe hdmi2 or input 1 or input 2, etc. Good luck.

Blue snowy pixel areas on my plasma


some of these panels were mis-calibrated from the factory after not aging long enough. Let the TV run for atleast 2 hours and adjust the Vs and Vscan voltages. When it is blue in the left I have found generally the Vs is about 10 volts too high.
