When first turned on picture is fine within 5 minutes all the black pixels turn red. This remains for 45 minutes and this time frame is getting longer. The TV then is fine. This only happens when the TV is cold. We have only had the TV for two months. The model #50PC3D
Well yes that would be great BUT I bought it from Best Buy (over the 30 day return)No return! LG sent out someone who knows NOTHING about Plasma TV's (told me so) LG won't send any one else!Well yes that would be great BUT I bought it from Best Buy (over the 30 day return)No return!

Hi, my problem is similar, but i have a plasma lg 42px4rvh. After turn on appers like a "frekles" in the screen, initial in the center of the screen and then is in all screen. I think that the problem is for the noise in the signal or the electricity. Please help me somebody.Hi, my problem is similar, but i have a plasma lg 42px4rvh.

During a commercial the picture went to black and white...odd...I thought it was part of the commercial...wrong when the game came back on the display glitched into 3 vertical bands of color.

By the highly technical manner in which you set forth the problem, I can see you are far more electronically savy than am I, BUT just a thought: Is there there any sort of timer setting in the TV menu which may be cutting it on and/or off, and which you have somehow failed to notice? Good luck. . .

Pixels on a plasma TV are from the zustain boards. You might have one or both of them about to go out. Horizontal lines are most likelly one of your buffers or the screen itself might be going bad. You can buy the sustain boards by part number that you can get from the board itself from www.interliquidparts.com
Unplug power cord- safety first!
open backcover
check powersupply- top center right is p.s.
top left side of powersupply you'll see 5 capacitor 3300uF 10V.
see any pop up on top? replace it All with same rate or 16v is O.K.
do not use temperature rate 75c. Use 105C.
if you know how to solder. you save $300 least!
THIS PHENOMENON IS A CHARACTERISTIC OF PLASMA TV SETS...KNOWN AS DIFFUSION ERRORS OR COMMONLY..SPARKLING...ON LG SETS...THE PANEL VOLTAGES MUST BE CHECKED AND ADJUSTED IF NOT WITHIN .5 V...PLUS OR MINUS..Vs...and Va...THE OTHER ADJUSTMENTS ARE ON THE Y-SUS BOARD..Vset DOWN...Vset up...RAMP up...RAMP down...these should be adjusted by professional tv personnel with experence...JOE ACE
