Zenith SJ2063S5 power supply problem

Interesting problem. With no fuses blown there is only approx 18vac at the 153V supply that comes directly off the PS diode bridge, yet the 120vac is present at the bridge. No high or low supply voltages present. Clicking the on/off switch does nothing. No degauss action. There is a spark at the AC plug the first time it is plugged in. Plugging the AC plug in/out after that there is no spark. I suspect an electrolytic but not sure how this PS start up circuit works.
