LG 60PZ550 color issue

[bgbarracus]

Hi there...hoping someone can help with the color issue im having on my 3 year old LG 60PZ550 plasma. Not sure if this is what is referred to as posterization or not. The problem primarily occurs on the top third and bottom third of the TV.

So far i have tried to reset the picture, no help. Ive checked the voltage settings on the power board and they were reading correctly based on the sticker. Ive also replaced the YSus board as well as both Y buffer boards and i still have the issue.

Following are some short videos i took of the issue: apologize for the reflection of the window in all

Thanks in advance for any assistance!

Could this be a zsus board issue because now there is a humming noise coming from the zsus board and the picture now has a layer of black splotches that slowly go away as it warms up. Would hate to replace that board as well but still be stuck with the original problem.

Think I would be more concerned with the two lines and strange image between them....

Prob mainboard fault if all the voltages are correct.
