ITS 8 yrs old a 60" ,all of a sudden, it has " color like
rainbows" if you turn off the set [tv] and then turn it back on,
the picture is perfect, for several seconds, then, thecolor rainbows
reappear, { "rainbows" for a lack of a better
description}like blurred vision, heavy in colors, I'm guessing it
needs some adjustment, but i lost owners manual. THIS is the first
problem I've had since new, thanks,jiw

Adjustments don't fix defective\failing components.

The smps for the convergence amp board is shutting down. It could be
the smps itself, or it's detecting excessive current draw from a defect
on the amp board (which could be drawing too much current because of
bad inputs from the correction generator section.

Have it checked professionally.

Couldn't it also be loss of color sync? In the olden days (vacuum
tubes, etc) this was much more common.

Ah, loss of burst or a drifting oscillator.......... I wouldn't mind
spending a day working on that stuff again.

I guess it could be anything from the OP's description, but it still
sounds like a convergence shutdown, not uncommon for these chassis.

Hey, where the hell are my 6GH8s!!!!!
