I have posted this in other areas and it appears to be a diffusion problem meaning the panel needs an electrical adjustment and can be done by a technician or you if you dare. Depends on how handy with electronics you are. But there are some adjustments you can do to minimize or remove these red or blue pixels firing randomly. Try adjusting V-SUS, V-SET, and check all other ones. VE, VS, VA, and see what happens. Write all voltages down first then go tweeking. I do have a bulletin here that states exactly what to do, I just have to find it. Let me know if you have any luck with this procedure first. Oh Yea, make sure you use the internal generator, the wipe screen from black to white so as to see both at the same time while adjusting the picture. It helps to have it on the stand when doing this procedure. Let me know if i can be of anymore assistance. Cheers. Jay

You seem to have what is called error diffusion. Either call samsung about it and arange service or do it on samsung.com. What kind of warranty do you have? Depending on your date of purchase you might be able to get samsung to help cover it or pay for it all.

SOURCE: Samsung Model: HP-R4262 42" Plasma Problem, pink pixelation/ghosting

Wow, I've been an installer and salesman in the consumer electronics industry since before the first plasma TV came out (Phillips 42" and Fujitsu 42" in 1996) and this is the first time I've ever seen that kind of an answer. "Take this to a repairman and he can add more plasma" what is the repairman a doctor. If it were that easy no one would ever have to upgrade or replace their screens. You can't add more plasma to a screen, if you don't believe me call Samsung and ask them for yourself like I did. I was actually so dumbfounded by your answer that I called a tech friend of mine at Samsung and asked him, his answer; "does this guy work for you?" I told him no and he said, "I was going to tell you to fire him because that's the dumbest thing I've ever heard anyone tell a customer".
What you need to do is take you plasma TV to an AUTHORIZED Samsung dealer/repair shop and inquire about the hazing/ghosting problem with them. Follow this link to find an authorized repair center near you: http://www.samsung.com/us/support/repairlocation/serviceLocator.do?group=&type=&subtype=&model_nm=HP-R4262&dType=D&mType=UM&vType=R&prd_ia_cd=&acc_ia_fl=&disp_nm=HP-R4262

SOURCE: Samsung S4253- No Image, Only Multicolored Pixels; Sound OK

The pink fuzzies come from a faulty Ymain. If you are looking at the set with the back off, its the largest board on the left side. Get the part number from the board and replace that one first. You may have to check the buffers or the logic board if this doesn't solve the problem but 9 times out of 10 when the picture is firing random pixels, its due to an overload in the Ymain (also called the YSUS).

Something is wrong with your logic board, you've got the option of returning this TV if it's still under warranty or buying a new one.

Blurry, purple bar across middle of plasma tv screen


Plasma screens are extremely susceptible to getting broken from any impacts to the face of the screen. What you are describing sound very much like distorted or dead pixels. It may not be a fixable issue, you may have to replace the entire unit or live with the purple bar. The reason you don't notice it as much when the screen is dark is because purple is on the darker end of the spectrum, and will be most visible in contrast to lighter ad brighter colors.

How do I fix dead ( not stuck) Pixels on my acer laptop? It appears like a smll hole in screen


You can't fix dead pixels, the transistor is faulty. This is indicated by black spots.

Stuck pixels remain a solid color other than white. This cane sometimes be fixed using software that flashes solid colors on the screen. Hot pixels remain solid white. this can be fixed in the same manner.

These are free software to fix stuck pixels.

White dots on screen


Hi,Yes your problem sounds like the DMD board.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screen. Here's a video that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q Have a blessed one!

The colors seem to be overlapping the red is further off than the other two


Hi, you might be experimenting a color wheel problem.The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will get color distortion ,black and white picture and sometimes you will hear humming noises.The other thing that it could be is the DMD board.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens.

Pixels aren't refreshing correctly in upper right hand side of screen


You might have a Service Co. come out and look at it. It sounds like the Z module is not doing it's job of erasing all prior images after a scene change. Some models there are adjustments for that internally. ( only for a tech ) Start a paper trail now.

Vertical black bar down the middle of hitachi plasma tv


Ok if your hitachi TV dies with no power anywhere try this:
Some models have a kill switch under the bottom edge. It's like a gray switch like a small light switch press it back in and voila let there be LIGHT. Saves you at least a $200 trip to repair shop!!

Green noise on all black images on my SAMSUNG LN LCD TV screen


I had a similar problem with my LG plasma. I used the Image Sticking Minimization
(Pixel Orbitor, White Wash, and Inversion) feature which is designed to prevent image burn in and ghosting. This ISM feature may be available on the Samsung or any other brand under a different name. I activated the "white wash" option for about 30 mins, the screen turns white and somehow the pixels get reset. The green noise disappeared after that.

I hope this helps. Phezbuster
