Entertainment Center: TVs, Stereos, VCRs and DVDs - toshiba TP48D50 convergence and pincusion problem

1995 toshiba projection screen with a bit of pincusion concave look and colors not alined..buttons on front panel don't respond on convergence line test,,nothing moves on grid ,,good voltage ,,guessing its the convergence IC's stk 392-020 on board ..
Does this sound like the culprit(the 2 convergence ic's)????

Good Morning, ff2002:

That would be my choice for the answer. When the convergence IC's fail, one of the first indicators is a pincushioning problem.

Do you need a manual for this set?
