Question about Samsung HP-R4252 42 in. Plasma HDTV

Open Question

Fireworks on the TV screen

I have a Samsung HP-R4252 and when turned on, it appears to have a flashing band of pixels in various colors. I have a Youtube movie of this. http://www.youtube.com/watch?v=a9FEqtrEW30

One of the processors on the the Y-upper buffer seems to have burned out as the soder is melted. So when I unplugged the lower Y-buffer boad, only the lower half of the screen shows up but with the same type of fireworks and no picture.

Any help would be appreciated.

hello,
I've watch your problem on youtube , that problem can be from main board. But to make sure main board problem, you should check without inputs first. Unplug all input (HDMI, Component, AV in, PC).
Than turn on your tv again. If that conditions still appear, i suggest you to call samsung technician to repair it.
Good luck.

How do I correct pink and green bands accross HP-R4252 Plasma TV


First of all try, changing the input device to some other and see whether you see the same problem. Then connect your present input to a different TV and see. If you feel the input is ok, and it is a problem in the display, this is a case to be handled by a qualified service technician.

Vertical lines across my entire screen


My 42" Samsung Plasma HDTV HP-R4252 has a 2" vertical strip of green pixels down the right side of the screen.

My 3 year warranty with Circuit City expires in Nov 2008.. so I hope I'm covered.. can't call until the morning.

Samsung said it might be a logic board problem.. but they want almost $2000 to fix. I might as well buy another TV if Circuit City can't fix it.
