Samsung screen problem	Can't Post

Hi all,
I am looking for some advice my samsung plasma has developed a 1 inch flickering line across the top of the screen. It seems to be multi coloured and made up of dots and small lines.
Any ideas what the cause is

?Old age?

No model - no hint as to vintage - that's all you get.

Hi Nelly1979!
Not that much amount of information. The plasma panel is wrongly controlled in horizontal direction.
Replace x-sus board and make sure before, that there is no possible power surge on secondary stage of the power supply, which could damage the new one also.
Model number wouldn't be that bad :-)

Hi Nelly1979!
Deflection boards = direction boards = plasma control boards like x-sus and y-sus depending on the fact if they are communicating with each other via a bus - system, which is usual needs a replacement of both.
Costs are around 240$ each board + repair shop's working time (approximately 70$ / hour) - So I would recommend to get the boards ordered online or via your local repair shop and replaced by yourself. it isn't that complicate. Just open the back housing (metal shielding) of your tv and carefully replace them with the new ones. Therefore it�s only necessary to open their mounting screws and remove their ribbon cable. To unplug that cables you need two screwdrivers (flathead - type) or a special tool. Pull out the side lock of the socket until the cable gets loose and carefully remove it from the old pcb. Do the same way at mounting the new board(s) and close the connection by hand.
In some cases complete repair kits are available from the manufacturer which include the boards to be replaced. It�s your choice - Beware that your device is out of warrenty before doing repairs.
However you decide - Don't buy a plasma again - they are famous troublemakers in tv repair shops.
