Plasma Screen flicker then goes black..sound works fine

TV turns on fine. But after watching for maybe an hour or so, the whole screen will suddenly start to flicker. This will happen for about 5-10 minutes, then the screen will go black. The sound is still playing though. The screen will flicker again, then go to black until I turn it off for awhile and then it will be fine...until the screen flickers again. I'm assuming its an overheating issue but any help would be much appreciated.

SOURCE: Flickering

I would suggest to call Samsung to get the Plasma repair under manufacturers warranty. The flickering will not go away until the hardware failure is corrected.
Good Luck.

SOURCE: Screen Problem

hi....Your tv picture is managed by several boards, the two specific ones are the ysus and the xsus. The Y controlls the horizontal pixelation and the X the verticle, if you are having horizontal problems then its the Ysus thats faulty, on this particular set, the Ysus board has two accompaning buffers that are particularly troublesome. I've had more than one of these sets in the shop recently with the same ailment.Sounds like your buffers are starting to go out. The screen is split horizontally by the two long skinny buffers attatched to the Y main, if the bottom one has one leg in the grave you'll be getting a partially black screen or no picture at all. The colored lines running through the screen are more typical of a failing buffer. Are you interested in taking this set apart and putting a couple hundred into fixing it?  When buffers go they usually take the Y main too. Worse case scenario you're gonna be out about $350 dollars to fix it yourself. Best case, a ribbon is loose on the bottom buffer and with a dismantle you'll be able to connect it again..

thank u rate me!!

SOURCE: Flickering/jumping picture

I HAVE THE SAME PROBLEM. TV WAS FINE UNTIL A FEW MONTHS AGO. OF COURSE ITS OUT OF WARRANTY. FROM WHAT I HAVE READ, AND BEEN TOLD, IT IS THE POWER SUPPLY TO THE UNIT. IT IS DEFECTIVE, OR IT OVERHEATS AND TRIES TO SHUT DOWN. A LAW SUIT IS IN PROGRESS AGAINST WESTINGHOUSE TO RESOLVE THIS MATTER. KINDA REMINDS ME OF THE XBOX 360'S WHEN THEY CAME OUT. ALL YOU CAN DO IS TAKE IT IN FOR SERVICE. OR, YOU CAN KEEP TURNING IT ON AND OFF, LIKE I DO. I HAVE HAD THIS TV ON ALL NIGHT BEFORE WITH NO PROBLEMS. AS SOON AS I START CHANGING STATIONS, OUT IT GOES. GOOD LUCK. WESTINGHOUSE WILL NOT EVEN EMAIL ME. I HAVE TRIED SEVERAL TIMES TO CONTACT THEM. I HAVE HEARD FROM THE LAW FIRM IN CALIFORNIA THAT IS GOING AFTER THEM. GO ONLINE, AND JOIN THE CRUSADE.

SOURCE: Screen lower half goes black/blank

The lower "Y Buffer" board is defective. Best repaired by a technician, or contact Phillips support for the part if you think you are able to replace a small circuit board on your own.

You have answered your own question, someone needs to open it and find a loose plug or broken solder connection--if it reacts to being tapped on that is the issue- a physical problem inside.

No picture on intermittent basis -


If you have tried using different input devices, looked for loose contacts
in power outlet, RC Jack, cable and connectors, the TV might need service.

Hello
I thinks you may be right. All plasma and LCD panel tVs will have cooling fans at the top side. Plasma screens will heat up much more, and if cooling fans stops work, of has damaged, the set will overheat, and awill automatically shut down; because there is a overheat sensor fitted inside it, will sense the heat, and if the set overheats, it will send a signal to the main system control fo the TV; which in turn shut down the whole system. look fans for proper working. If not replace them. OK.

No picture, sound ok


I have a similar issue. Sometimes the entire screen goes black and sometimes only one-half - either the top or bottom half goes black. The only solution we have found is to gently tap the TV (usually the front side) and the picture will come back for awhile. It almost seems heat related as it only goes out after the first 10 minutes of use. There must be a fix to this.
