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

Noisy jumping red pixels in the upper right corner

You are right, this is caused by a faulty power supply that gives you bad voltages. So it can get worse in time.

I have whats called "red

You will need a small philips head screw driver and a Digital Volt Meter for this.

Unplug your set and take the back off
Plug the set back in and turn the set on
Now with your meter find the test point on the power supply that says VS. If you cannot find it, you can measure it at the plug of the board.
Make the sure the voltage matches the sticker that is on the panel. It will say VS. If it does not match, find the VS adjustment pod and adjust the voltage to match the sticker. If the voltage already matches, it is safe to raise 10 to 15 volts. If the picture starts to clear up, you are going the right way, if it gets worse, you need to adjust the other way. If it doesn't change at all, then odds are you have a bad panel.

The model is Samsung LN-T4661F. It power cycles at least 3 times every time I turn it on. Once the screen comes on there are, most times, pink pixels randomly all over the screen. I have to turn it off...

good day .maybe theres a defect in the board causing the screen changes abnormally. maybe the screen module is defective. just consult that problem to samsung service center to fix your problem.

Samsung HD tv help

Is it a Plasma Television? I recently had a customer have the same issue with a 2 year old model Samsung 50" plasma TV. In his case one Of the computer panels failed. He didn't have a service plan and the warrenty was out, so i directed him to Samsungs help line. They inturn directed him to a authorized repair center. Repairs were roughly $800. Thats a possibility but it may not be the same as your issue. Try leaving your TV running for a little while when it has the issue, and see if it eventually goes away. Some older plasma models have started to require a warm up time for the pixel cells. This has been a down fall of plasma that for the most part no longer exists on newer models.
I hope eveything works out.

Have a great day

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.
