There seems to be an overheating issue with your plasma. If the plasma has internal cooling fans, I would suggest to check them for proper operation.
If the fans appear to be working properly, there could be a power supply that is startting to fail due to heat and it will need to be service.
Let me know if you need further assisntance.

Plz check if the internal cooling fan are in good working condition. avoid keeping magnetic elements..eg.speakers, very nearby.

Hi Mikshanks,

I had the same problem with my TV. It was a horizontal problem with different shades of color, and black spots. I replaced my Upper & Lower Y-buffer boards. Your Y-sus board should be okay since it still powers on the screen. You should replace the Y-buffers Upper & Lower, and it should work. I hope this helps.

best regards,
Tyler

Colorful "speckles" on screen


Could be the screen burn from watching T.V. on a show and the thing burnt in (in this case the colors, yes it can burn colors.) and there's nothing you can do. The insides of the T.V.'s have plasma gases which can flow out of control.
