It seems to be a pre convergence issue. It needs tech to get the convergence issue fixed
If you know basic electronics and have little experience of solder work then you can fix this TV as your TV has cold solder joints in convergence out board.
You need to resold these joints / pins of IC
Thank you.
That is one of the convergence ICs starting to fail.
I will give you more information.
There is a convergence problem, the convergence ICs on the convergence board are starting to fail.
You need to have the convergence IC tested, either replace the ICs or the board.
The best thing is always calling for repair.
If you want to do it yourself buy the service manual.
Perform a service setup procedure first, then test the convergence ICs.
You can replace the board , that is expensive, or the ICs that are about $8 each.
You can find parts and service manual at Vance Baldwin Electronics or partstore
give them a call.
See here explained how to replace the ICs

Usually consumer described bowing is bad solder connects
on pins of convergence IC's. If the effort is made to pull the center PC board out,then replace both Stk392-570 IC's for
durability.
Note: V-Pin amp and pin out relates to left/right side bowed-in
issues,a problem not usually found on your model.

I understand and can resolder these joints as recommended. I have the back of the TV off and am not sure what I am looking for. Each of the 3 tubes has a board attached, are these the conversion boards? The only pins I can see to resolder are two pins that directly attach to the tube comming from these boards. Is this the location you recommend for the repair?
