Samsung plasma tv hp-r4262

one of your buttom scanning bords is dead or it needs to be cleaned or simply reconnected properly , at the buttom of your plasma tv you have 2 to 4 small boards with flex connecters one of these flexible connecters will be adjacent to the black line ,replace entire board because it cannot be repaired

I really do not know there is the "Stuck Pixel Fixer programs" I think that Program Breakdown another IC. For this issue is absolutely the Plasma display panel have problem. You shall exchange it.

sounds like your Y or X buffer or driver main is going bad .

Most likely the lower buffer board " E " needs to be replaced. Right now I'm working on repairing a 42" Samsung plasma HP-R4272. The Service manual for that TV says for trouble shooting for that problem is the lower buffer board " E ".
Best to find the correct Service Manual for your TV over the internet to get the correct part number for replacement. The Service Manual should be less than $20.

There are horizontal and vertical relays in plazmas that go out over time and cause this to happen , You can get an estimate from a local tv repair service in some cases they can give it to you over the phone. Good luck.

The plasma display screen is made of a matrix of elements connected to cables along the side and top. On your unit, some of these many, tiny connections are making contact intermittantly thus losing the elements in that area. These contacts are held in place with just pressure and if that is disturbed, you lose that line of elements. Try squeezing the cabinet of the TV on the outside at the top in the area of the loss and see if that makes a difference. May have to go inside and see if the contact assembly is disturbed or warped or something.

I have been trying to fix one of these tvs and found out from a repair man that the lower half going blank means a problem with the lower buffer. and that is also what the manual I downloaded says.
have you checked that?

this problem is a bad panel it needs to be replaced in some cases the panel is under warranty. check your warranty.
also the E and F buffers could be at fault I would have these replaced first.
