You might what to check the power supply module, for bulged electrolytic caps, on the power supply module.

I don't have a lot to go on. If this is an older rear projection, this usually means the face of the green picture tube is dark (the picture goes purple-red) or there is too much red tube(excessive drive). This is a technical adjustment as it is in an area containing hazardous voltages. Adjustments will be a stop gap as rear projection TVs are all past their usable life span (About 8 years + with moderate use)

I work as a Contractor for Vizio repairs, and I can tell you that the only solution is to replace the motherboard, or if under warranty REPLACE IT! I have had situations when I replace Motherboard and within 2-3 hours the TV is making either Green, Red, Or Blue pixels where dark areas are. If under warranty don't accept any thing but a full replacement.

This is not a simple question to answer without looking at it, my recommendation is to call a service center in your area. That's my professional opinion.

Go to Vizio website and buy the extending warranty, you need to have your TV replaced since the problem is with the screen itself.

Call Vizio tech support and start a case. i am having the same issues with mine and i have sent it back. they will be replacing it this time.
