A Mitshibishi Problem

[jstout66]

I was hoping maybe someone would have advice on a TV problem. I will also post better info when I have it. (model number etc...) But here's what I know so far. A coworker of mine called tonight and wants me to look at their tv, as they assume since I collect and attempt to work on old sets I must be able to work on anything. Anyway...... They have a circa 1995 Mitshibishi 36" console. They said within the past 2 weeks that on occasion they might see a flash of green or distorted color. They said they turned it on tonight and the picture looked like a picture negative. No onscreen adjusting seems to work. I'm assuming it's a cap. I guess what I'm asking is, if any of you repaired these are you aware of common problems. I know NOTHING on newer sets, especially a Mitshibish product. Your comments and input will be greatly appreciated. Thank You.
