yoke as in the yoke board on the back of the CRT?
i'll reach in there and see if it's loose. what is strange though is
that moving the unit or tapping the body of the CRT has no effect on
the picture which i would assume it would if it were loose.

question... i mess around with arcade machines and monitors so i have a
little experience with discharging monitors and staying clear of the
annode cap and wire, etc... but on this monster... what exactly am I
watching out for? i guess i could just trace the wires from the flyback
and steer clear from there.

also.. i located the 2 "stk" IC's on the heatsinks. they're held in
with 2 screws so i'm assuming they're socketed unless that's what holds
the heatsink to them.

1. where would I get replacements for these.
2. doesn't each gun have individual convergence circuitry?
3. where (if anywhere) can i find the service manual for this tv?

thanks for all the help so far. i'm confident i'll get this fixed.
