Westinghouse LTV-32w1 Color problems - HELP

For the past few months I've been having problems with my 32w1. I've had it for years and it's been great to me but recently it will change its colors settings randomly. I can go in and fiddle with them but it's not guaranteed that it won't change colors on me again. I want to keep this TV going since it's a great TV for my bedroom but i'm not sure if I can fix this. Does anyone have an idea of what we can do? Thanks a lot!
