Screen Problem After watching my Samsung HP-R4262 plasma tv for 30 minutes or so half the screen goes black from the bottom up.  Once it starts it continues to do that intermittently.  I've had the tv for 13 months.

had the same exact problem. The customer service people at samsung were **** and had no clue. After doing some research I narrowed ti down to two potential problems. First one was check for the blown capacitors on the power suplly board. You can find lots of forums on this and is a very well known problem with samsung. Second, which was my fix, is try the firmware update for your TV from the samsung website. The rpoblem was fixed in 30 seconds and no money spent. The clicking and tv on and off problem is gone. Good Luck.

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

its ur diaplay problem.. go for a change of new display...

the HDTV has a heat-related problem check your fans. Do they remove heat? the vertical chips paint the screen from top to middle and, middle to bottom so; your top to middle vertical chip is overheating as is your video chip; that is why you have "glitter" in the back ground. get rid of the heat or, bye,bye TV.

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!!

you need to replace y-sustain board.

The x drive board is bad in the area you see as black. OR the cable came loose.

It looks like you got a bad Power Surge thought your Power Cable. There is a card in your TV that handles that. Unfortunately their is little you can do but bite the bullet and pay to have it fixed. First call Samsung and ask if this has happened to anyone else.

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.
