Question about Samsung HP-R5052 50 in. Plasma HDTV
It starts with black patches of pixels then as it warms up those patches go away but the overall picture is washed out, kind of yellowish/pastel color. Do you know what board could be failing ?

some of these panels were mis-calibrated from the factory after not aging long enough. Let the TV run for atleast 2 hours and adjust the Vs and Vscan voltages. When it is blue in the left I have found generally the Vs is about 10 volts too high.

its the lower buffer card.. (y buffer lower board) they cost about $90.. i changed mine myself on my samsung hpr-4262 42 inch plasma.. pretty easy,, took approz 20 minutes.. the card has 3 ribbon cables and 3 other connectors and 1 screw.. removing all the screws out of the back pannel took the most time.. i found the repair manual for my tv on line for $13 (download PDF file) the manual had a trouble shooting section and what board to replace for each problem.. got the manual from here http://store.payloadz.com/ ordered the replacement board from www.partstore.com

It related with Power Board(50%) or Y-Main(50%).
But, if you use the power bar with surge protacton, need to check
the power bar's lamp when the TV is turning on & off.
