pincushion trouble]]
I paid Robert at Philips tech assist "900" tech about fifteen bucks to
tell me R818 is a 10 ohm 1watt,and to change C811 (1.5mfd)cap as
precaution.
I also changed the power transistor mentioned, Q803 (which tested good)
because R818 went to it's emitter.
Powered it up,about the same side -distortion (and a vert retrace at
top),with a hot smell.
R818 was very hot.
I am at a loss.
I need help.Philips are,aparently not "up" on this chassis.
