Television and Home Theater

Hello. Iv been having some trouble with my HD samsung 42' tv. I had problems about a yr ago. THE ic convergence went out. Got them replaced and it fixed the problem. Well sunday it happened again. Looked like the same problem. Mirror images. So i replaced them again. It looks the same though. still mirrored. I go to the Config screen and try and line up the colors. I see Red, Blue fine. I can move the bars but the green looks very fuzzy and blurry. Red and blue are crisp and clean but just the green is blurry.

Can any one tell me the set up code for a Symphonic model LCD B20B6 - I've been trying to programme a TOTAL CONTROL remote but there's no code listed and the quick set up method isn't working. If the remote I'm using doesn't support this TV does anyone know one that does or where I can purchase a new Symphonic remote?

i hav model#hcn4727w and the screen is purple i took the back panel off and noticed that the green light is off what part should i buy 2 fix this? or is there something else i can do 2 fix this problem? i hav no manuals so i really dont no wats wrong with my tv
