This is a project and money saver for my retired dad, so not likely. :)


Yes, my mistake.


Okay, the CRT doesn't appear to be low on coolant. I did look inside
through the lens with the set on. Knowing that the skew was on the left
side of the screen, I looked into the lens of the blue CRT and on the
right side and I could see the skew very well. (It looked as if a sheet
of clear (or blue) plastic was in there and it had an upward curve in
that area as if it had been heat warped. I realize there isn't a sheet of
plastic in there, that's just what it looked like.

I replace the front screen and tried the user convergence adjustment
again and the blue + that is usually over the white(red/green/blue) +, is
way over at the left edge so that I can only see the right tip when I
move it to the right as far as it will go. I can see that tip move
up/down/left/right, although if I move it left, the tip disappears.

So...anymore ideas or information you need to help diagnose this?

If the CRT is bad, what will a replacement cost me?

Thank you,
Tom

Oh I forgot to say, check the resistance of the good yokes and compare it to
the questionable one.

Or just swap the plugs with one of the other yokes and see if the
problem stays with the same color.

Wish I had thought of that...but that's one of the cool deals about
troubleshooting projos..redundant circuitry.

I'll get to this and report back.
