I had a TV that I got about 5 years ago. It was a Magnovox probably a 30". One day I noticed a green area in the upper left corner. No biggy. A few days later it had grown to a patch across the top. A month later the whole TV reminded me of what it's like to wear 3-D glasses. So I bit the bullet and bought another TV this time a flat screen but still a Magnavox. I don't care, I think they make good TV's and that was just a fluke. The other night I noticed Miss Marple's hair was an unsightly green on the left side of her head. I thought OH NO not again! Then I remembered someone in the program telling me my old TV wasn't probably broken but it was because I had my stereo speakers on each side of it. I jumped up and moved the speakers and Miss Marple's hair was immediately a nice uniform grey. It stayed that way through the whole show. She caught the bad guys, don't you know. So looks like I didn't have to get rid of the old tv but I really do like the new one. So don't put you speakers beside your tv even if it already has speakers built in. It's really not enough shielding.
