Blue Noise/Pixels Bottom Left Corner of my Samsung Plasma
There is a lot of blue noise/pixel spots that move around the bottom left hand corner of my Samsung HP-S4253 screen & I saw in another post you said lowering voltage helps these problems, but how exactly do I do it? Any help would be very much appreciated!!! Thanks!!

I have the same problem -- had a Best Buy technician out 4 times so far, replaced 2 parts, adjusted the voltage, etc., but still have the same problem -- looks like there may be no solution other than replacing the TV, which is an expensive proposition considering that mine is about 18 months old.
This is a diffusion problem and can be solved by lowering some voltages in the television. Sometimes it is the powersupply though. But you can try adjusting V-SUS and V-SET and V-SCAN for best picture. But you have to switch between light and dark sources to make sure you got it all the way. One quick pattern you can put up is the burn in protection screen. The Wipe one from black to white while adjusting the set. Let me know how this pans out for you. Good luck. Have fun. Jay
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.
You need to adjust the panel voltages, adjust the VS voltage to around 186 volts, if that doesn't change it then adjust the V-Scan voltage down, turn the unit on and apply a video source to it, and while adjusting the voltages look at the screen and you should be abe to watch the video noise fade out.
