Convergence on RCA P56940 chassis PTK195 can only be done by service center with RCA Chipper Check computer interface box. Sounds like possibly missing -15 volt or +15 volt supply to digital convergence circuit, bad i.c.'s U19503 or U19504. Supply voltages come from regulator supply transformer T19701 diodes CR19707 (-15 volts) and CR19709 (+15 volt)
