All red picture now.

Question

I loved this TV until yesterday.I turned it on, and first I noticed very slight changes in color (like the drift you get when you try to display a dvd signal on a vcr), then it went to different colors, mostly pink and violet. Now it's all monochrome red and that gets brighter and darker whenever it likes. I tried turning it off for a while, but there was no improvement, except that it shows a good color picture when it first comes on and quickly becomes red monochrome.
