Samsung HP-S5053 distorted pixels. Bad Panel?

[Shane711]

So I got this Samsung HP-S5053 and I am guessing the screen/panel is bad. Everything else seems to be working perfect. Here are some pictures

Looks like a typical (X) z-sus board problem.

I agree Z-sus bad joints on inductors

I'm going to disagree and say problem on the Y sustain.

chrismurphy:

This is a Samsung with X-Main and Y-Main boards.

Are you accidentally thinking of the poor solder connection of large coils on an LG plasma instead of a Samsung plasma? This problem may not apply here.

Shane711:

This may be a similar problem to older LG plasma TVs with IPM (Integrated Power Module) under the large heatsinks. Sometimes the IPM can fail (not completely) and yield such image problems.

If the IPM modules are not failed, it could require a small adjustment to one of the 3 potentiometers on the Y-main board or 2 potentiometers (for Va and Vs) on the power supply.

Take photos or clearly mark the EXISTING position of EVERY POT.

On power supply: Take measurements of Va and Vs voltage to confirm these voltages match the label on the back of the panel itself. If they do not match, try to adjust to match panel specs. Do not go too high or you will risk damaging poser supply or other boards and force TV shutdown.

On Y-Main: Then try very small adjustments one at a time to see if there is any improvement to the picture quality.

Sometimes the panel requires small adjustment to these pots as a panel ages.

I've tweaked many older LG plasma panels to improve picture quality or remove sparklies from dark areas of image.

Adjustments should be done on warm TV after about 15 minutes of use.

Edit:
Also, double-check that the color settings in the user menu are ok (neither max or min) I have had Samsung TV and monitors that lost their settings and adopted crazy value outside of acceptable range limits... Adjusting and saving can fix menu value problems... I doubt that is the case here but cannot be ruled out.
