Samsung 42" plasma hdtv

Screen shows approx 12"x12" area of pink dots in the middle of the screen like a sunburst. The "suburst flickers on and off. It seems to occur more when the room temperature is hotter or the tv has been on for a longer time. Any ideas?

Black bars to pink dots are all symptoms of the logic board failing. Samsung p/n# BN96-02042A and this isn't a repair for the novice. The board itself contains many small smd caps that are the likely culprits. But the fine wire traces on this board make replacing the caps nearly impossible without some very sophisticated smd removal equipment and a magnifier that could double as a hubble telescope. Most shops merely replace the board. They're about $180 plus shipping and core charges. If you want to price it goto vance baldwin's site https://www.vancebaldwin.com and enter as a guest. Select parts and enter the part number above. It's about 1-2 hour install and re-assemble barring any complications. Find a reputable shop and take the unit in yourself. That will help keep the cost down, but expect that this one will cost in the neighborhood of $375 - $450 and could run higher if anything else is found wrong. If you need some help finding a good shop try NESDA, National Electronic Service Dealer's Assn., for a member shop near you. http://www.nesda.com/locator/state_search.php Good Luck Bill

Blue dots on black images

I can tell you that I had my plasma screen replaced in the 4th year. The tech told me that the replacement panel was much more reliable. You may be looking at replacing the plasma panel...(which may be more expensive than replacing the whole unit??).

Samsung Model: HP-R4262 42" Plasma Problem, pink pixelation/ghosting

Onece the plasma heats up it shrinks a little, i think the cause is that you are low on plasma, so when i heats it shrinks and since the plasma cycles, the area low on plasma wil move slowly around the screen, take this to a repairman and more plasma can be added to it.
