I do believe the Panel is bad and needs to be replaced. Check with the manfacture to confirm this.

SOURCE: screen went black on my 42" sanyo model dp42647 lcd

Hi there! The panel may be in protection mode. The Inverter board is the most logical area to start after checking power supply Voltages.(5,6,24 and 13Volts). There may be coils on the Inverter Board which have bad soldering or faulty. Other than this it may be main board which controls switch on or off. If all else fails, refer to a repairer. Beware of High Current!!! Best Wishes and Good Luck, Jus004

SOURCE: No power to my Phillips 42 inch Plasma

Most likely it going to be a power supply related problem. The red blinking light is a code for a TV tech to diagnose the problem on the power supply board itself or the board that regulates the power for the screen. Some manufactures call it a Backlight Inverter Board. A TV repair shop should be able to look at it for you and tell you which board is bad.
Replacement boards can be found at a good price at Shopjimmy.com

My Plasma TV is having problems on Channel 31 (not sure of the frequency assigned)


Do you have an old VCR? because they used to work around this channel. If not forget what I said. If so, try changing the output, or if you don't use it, put it somewhere else.

I have a HP notebook laptop that I am trying to connect to a Sanyo 42 inch Plasma HDTV model DP42740 . I have VGA , S-video ,and an Expansion port 3 jacks coming out of my laptop. What way would you...


That television doesn't have a VGA input, but it does have an S-video in. So this is the cable that you would need to connect to get the video image on the screen. However, s-video does not carry sound. So you either run the sound from the laptop still, or use the earphone jack to bring the sound out to your surround amp, or tv.

My sanyo 42 inch plasma has a blue screen, i can hear the sound on the tv but screen remains blue. can u help please


Be sure your channel settings are correct and that you have proper orientation of the hook up cables. See if your remote has a video-mute if so turn it off...a video-mute will produce a blue or black screen. To be sure its not the tuner that's enter the menu screen if you can see the menu then the tuner is ok this means the down-stream video is functioning. Be sure to have all your input devices set to the correct output ports. If all check good and still blue screen then the logic section is not processing video codecs and needs servicing.

Tv keeps turning on and off


You probably have blown capacitors on the PSB-power supply board. Recaping with new UF caps works 90% of the time. The set turns itself of into a fault protection to keep from damaging more components internally. A few bucks a soldering iron some solder should do the trick.

Red line running through tv screen when tv is on


The individual dots (pixels) that make up the picture are controlled by vertical and horizontal drivers that are rapidly switched off and on. They are arranged as columns and rows with these further controlled in time in a synchronized fashion. The line is being caused by a driver that is failing.
Depending on the degree of integration, these final integrated circuits may be part of the display and not individually replaceable by hand. You may only have the option of replacing the screen with the failed part. 
It will be necessary to contact Sanyo (who may not have manufactured the set) to find whether the repair is cost effective.
