I'm sorry you're having trouble with this TV, I need bit more info to troubleshoot the problem.

- Can you please connect a video source in AV input (RCA jacks at rear of TV) as a test to see if TV gives same picture problem?

I have a VHS player installed, we still watch them. Let me see if that does the same thing.

Sorry to hear that, does the picture problem fix itself after some time?

Customer: replied 2 months ago.
No, it goes in and out, gets a little better, then goes back.

OK, there are few possible things that can be cause of these symptoms, either t-con board is bad or LVDS cable connecting t-con board to main board is misaligned or defective or the main board has got internal failure and generating purple and green color effect on picture while processing video signal. You can expect around $200 to $350 repair cost (parts + labor) from local TV repair shop.

I'm sorry there is no easy or quick fix for this problem and it is definitely hardware failure that needs defective board replacement to resolve the issue.
I trust my input will help you out to make decision about this TV repair or invest that money on new replacement TV.
