Resolved Question:

Hi ***** 50'' plasma (TX-P50G10B) has been having screen issues for a month or so. There is a circular rainbow effect which distorts the colours on the screen and renders skin tones to an artificial level. I bought the TV in Nov 2009. I have read that plasmas tend to have a limited shelf life but i expected close to 8 to 10 years not 6. Can this be repaired?

Thanks for the picture which helped a lot.Its either incorrect Vsus volts that should be adjusted or power supply board has got failing capacitors that causing incorrect volts output OR A board is suspected that provide video data to plasma panel to make an image. Please check Vsus volts on power supply board that should be as per label pasted on plasma panel rear side and if Vsus volts are fine then A board swapping is required.I trust my input will help you out.

Hi
How do I go about checking Vsus volts and how would I adjust it? If swapping a board is needed, how is it done? I'm a complete novice with electronics.

I'm afraid a novice should not attempt it because you would be dealing with high volts in TV and electric shock risk is involve, for your won safety it would be better to call local TV tech to do this job.Thanks.
