Ronnie,
I posted the same problem last week. My convergence is really bowed and way too
wide..if you find a
solution, let me know.
After two days on location, I decided to make arrangements for the set to come
in the shop.
I did get fairly close by starting our at level 2 adjustments, but eventually,
I would lose video for some
reason and have to press "clear" twice, then power off and start all over.
The calibration setting seems to affect your adjustments, if it was tried when
the convergence was way
off.
Get it as close as you can, then try the calibration, then go back into level 3
and try adjusting it
again.
BTW, the set came to be with a bad CRT and another shop had cut the focus and
HV wires from the FBT. I
didn't notice it until I powered the set up and found the focus lead arcing to
a heat sink...sounds like
we may have the same problem.
I expect the set Tues so I can work on it in more detail.
If I find the problem, I'll post the fix.
Jeff

Set had a bad focus/screen assy and my apprentice installed it and reversed
the focus input wire with one of the focus output wires "grrrrr".
Afterwards, that somehow fed back and knocked the convergence
adjustments way off and also now the last 4 convergence menu adjustments
will not adjust at all!! Picture is bowed particulary on the left side of
the top and bottom. I do still have all my B+ voltages to the conv. panel.
Any ideas would be very much appreciated!!
