Tv turns on and off

SOURCE: Samsung 50" plasma won't turn on

My 42" plasma is making a clicking sound, then it switches off and keeps clicking but not switching back on, when it does go back on it stays on for just a few moments, it is only 14months old.

I had the same problem and had the TV serviced and found that the y board was blown $350 total. The repair guy explained that the board has a hot transister underneath that slowly leaked onto the board, but says that they can not get Samsung to admit to the problem. Works fine now but only have a 90 day warrenty on the parts.

My Samsung 52" plasma TV will shut off while watching TV. It will do it repeatedly and we have to turn it back on. Is it overheating and shuts down? How can this be fixed?

Below is the service manual link from epox. ftp://ftp.epox.com/downloads/Manual/mu-8KDA3J&+11.pdf

This is usually a switchmode power supply problem, and it's shutting down, for safety reasons, so as to avoid a fire and explosion or both. Realistically you need to get a "Quote" from an authorised service agent, for repair.

SOURCE: error diffusion on Samsung 50" PLASMA TV

Yes the diffusion problem on your tv is due to the pdp panel aging. What you can try is readjusting the VSCAN voltage, there is a test point marked VSCAN using a DVM you can first check the voltage, should be around -- 190 turn the adjustment counter clockwise this should reduce the voltage, watcthing the picture turn control untill the sparkling pixels stop. That should do it. The panel is starting to age this may occur again until you can't adjust it out meaning a bad panel.
