[TechAssist] zenith RA50M84D1 convergence prob

RA50M84D1 ZENITH bigscreen GM chassis A-line.  Bowed convergence all
colors. Can adjust with customer convergence and service adjustments.
R4163 1 ohm resistor getting hot stks also running  hot.  +26vdc
-26vdc  + 16vdc coming to the convergence module (9-1690)  checked
filters on the supplies on the 9-1978 sweep board. Changed the stks on
the convergence module with no change.  Vert seems short cannot get a
full screen with the height control when the convergence is disabled.
Any suggestions?
