Question about Sanyo Televison & Video

1 Answer

Sanyo dp42746 turns off then turns on spontaneously

TV picture will suddenly lose signal and go black. Then, signal will return and picture returns. At first this happened occasionally but now it is to the point where it happens every 15-20 minutes and it takes longer for the picture to return. Please advise.

    Sound is also lost as well but returns when picture returns.

    Additional info...when the signal does return the input component box appears briefly in the upper right corner before the picture returns.

The TV should be under warranty. Send back. Sounds like the panel is faulty (half the value of the set).

SOURCE: lag in video to audio on Westinghouse LCD 26' TV

Register your tv (whether under a year of date of purchase or not) and get a firmware update. It is simple and works like a charms, sync of voice and images is great afterward.

Make sure you unzip the thumb drive download b4 installing on tv.

SOURCE: Screen goes black, still have audio

I first changed the 220uf capacitor with no luck. I flipped the BURN switch to on and the set has been working great for a week now. Daughter left it on for about 20 hours overnight with no problem. Anybody have an idea what those 4 tiny switches are for? I have heard these type of switches called "dip switches". They are tiny white switches in a yellow block on the lower left side of the upper circuit board. The top one was labled 40", the next one down was labled 46", the 3rd one was 4 letters "EW" something I think, and then the bottom one was labled "BURN".

I have a sanyo DP42746 42in. Plasma. NO picture no sound.


EVERY brand has failures.

This is why I recommend buying the extended warranty. The repair would cost about $300-400. It is most likely the power supply, you could replace it yourself, but the parts are very hard to find.

Black screen of death - DP42746


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:

If you would like to be compensated for your TV please contact me @

There are no fees or anything to do so.

Denon 1905/785 - lost color feeding tv


Your Denon 1905 might be setting it under HDMI for video source.You need to correct it by going to menu,as you browse through the setting,you should able to find video select or video output. It is on the manual.
Remember,you need to run a composite video cable from the video output behind your receiver to your TV video input for this step.

Hi there!
