[TechAssist] Re: Toshiba PTV Mod P48E61, Chassis TAC9550 Convergence Prob.

This set uses STK392-110, one for RGB vertical and one for RGB horizontal
That is the most likely failure point, although I attempted several years
back to replace the op amps on the Digital convergence board on 1 or 2 units
(RARE repair!!). Whatta pain that was--multi layer connections.
 Eventually had to replace digital convergence board U701 -Board # PB5514.
Part # 23704186. (3 different boards for different models)

I don't expect you to have to replace this board, but you have the info,
just in case.
