Maybe I should obtain a manual before attempting a repair, Or ask what could be causing this. I was thinking about gutting it and putting an HD lcd screen inside it. But if anyone here wants to help repair it. I'll keep it around. Possibly sell it.

Brightness also seems to be dull...even though i turn it up all the way and make various adjustments. There is a light sensor on the front to help minimize glare...but even with a bright flash light right on it. The picture is not very bright. And the whites over power the other colors.

Various issues with red tint. front panel adjustments do not correct this. It's like a shadow on people and text. Text is un readable, because of fuzzy white with red shadowing. completely blurs it out unless it's huge or in the center of the screen...

Sounds just plain worn out to me. Repairs would probably not be cost effective.

Symptoms seem to describe a gassy crt. See post above for appropriate action...
