On the "Pin Mod Assy 31 inch" # APC026-A001 pin cushion board I found a
1W grey resistor R818 open.NEED VALUE. This resistor goes to emitter of
power transistor Q803 (421-6) on same module. Q801,2,3,
electrolytics,diodes, all check good.I assume R818 did not self
destruct.What else may have taken it out.Excess current thru Q803 had to
do it, but why.
