Most times this can be corrected by the correct alignment of the diffusion. The unfortunate part is that will require a tech that knows how to set all of the power supply voltages and then align the diffusion pots on the ysus pwb. This could mean a defective ysus bd. but most times the alignment will correct this problem.

I have poor color and when the screen is dark many red green yellow dots dancing all over on my LG 42 PX5D


This is a common fault on all LG sets with few people offering any solutions. I can offer a solution that could remove 95% if not 100% of the dots.
Remove the back of the set, there are about 40 screws. On the left hand side on a circuit board you will see 3 or 4 blue plastic boxes with yellow screw adjusters in them. The only 2 you are interested in are VR3 "setup" and VR2 "setdn". Mark the location with a marker pen so that you know where the factory settings were. Then turn VR3 fully clockwise. If this does not get rid completely do the same with VR2. This worked for me today, I was about to throw the TV away but I now have a 95% improved screen, sharper and more vibrant picture and saved hundreds. Hope it works.

I have dots running across the screen


If the dots are red and green, that's normal. Just enjoy your hd picture. actually, I think the dots make it look clearer. The only time I can really see them is when the screen is black.

Plasma tv has little red dots in the black


This problem (known as sparkles) can be cured by adjusting the ramp control on the Y-Sustain board. If this does not cure the dots then there is a software remedy for the control board which an LG repair centre could fix. Failing that a replacement board is required. The orbitor & whitewash are like screen savers to help to prevent a screen burn from a permanently displayed image.

This problem cannot be corrected without disassembly, and the proper adjustment of the power supply voltages and the diffusion adjusment of the ysus pwb. This will take a qualified service tech that understands plasma technology.

LG PLASMA TV WITH COLOURED LINES OVER SCREEN


If the Video (Picture/Pix) is gone but you can hear the Audio (sound), then it could mean the YSUS PCB Assembly is gone/kaput/finish. Can replace the PCB, not repair the PCB due to timing circuitry involve. Cost maybe roughly $500 depending where you located. The PCB is located on the left hand side of your TV when you are facing the back (Back open). Might find 3-4 brown flex membrane connecting to the plasma panel. The PCB has a silver or black aluminum heatsink (big) on it.
Good Luck.
