Thank you for using JustAnswer.
Your TV has a convergence board problem which is very common with these types of TV's even on other brands. The fix for this is replacing two identical components (IC's) with part# XXXXX But before replacing these IC's technicians check small components called resistors and pico fuses which are located around these IC's. They also check for loose or cold solder connections. The repair has to be done by a qualified technician because there are parts inside your TV that still hold dangerous amount of voltage even if it's unplugged from the wall outlet. It would cost around $300 to fix your TV and would advise you to just put the money on a new flatscreen TV.
I hope this answers your question and if you have more please feel free to ask.
