Question about Samsung Televison & Video

1 Answer

Hi - we've just got a brand new Samsung c450 42" plasma. Its been okay for about 5 days, but tonight approximately 7 or 8 white and coloured lines have appeared vertically on the right side of the screen. Any ideas please? I'll be gutted if this is a donkey! Cheers.

If it's a new TV take it back! There is a problem with either the PDP or the Y Buffer board. If it's still under warranty, call Samsung and have them fix it.

If not, are the lines pink? If they are clustered in 1 or more strips (usually about 3 in apiece), the Y Buffers are starting to go bad. Do not watch the TV - it may cause more damage and blow the YSUS board if this is the case! Replace the affected Y Buffer, and the lines will go away. I had to replace the upper buffer in my Samsung HPR4272X/XAA (my [3] strips were horizontal, and on the upper half of the TV).

If its the Panel, there is not much you can do about it (at least in my experience) except replace the panel. At that point in time, it's more cost effective to get a new TV.

Good luck!

Other than taking the television to a repair shop not much can be done. I recommend a new television. Excellent brands are Sony, and Samsung. Both brands are quality televisions. Best of all you can order them on Amazon.com for lower prices.

LG PLASMA TV WITH COLOURED LINES OVER SCREEN


If the Video (Picture/Pix) is gone but you can hear the Audio (sound), then it could mean the YSUS PCB Assembly is gone/kaput/finish. Can replace the PCB, not repair the PCB due to timing circuitry involve. Cost maybe roughly $500 depending where you located. The PCB is located on the left hand side of your TV when you are facing the back (Back open). Might find 3-4 brown flex membrane connecting to the plasma panel. The PCB has a silver or black aluminum heatsink (big) on it.
Good Luck.
