this unit sounds like the emerson model ewc1302 which should be in the
members download area its also a sc313c symphonic i've had a few of these
with that problem most of the time the optocoupler is bad (ic601) or pcb
cracks in that feedback area.also check d621 for leakage and r566 3.9 ohms
in series with r565 & r570  vcc supply to vertical ic (pin 2) hth
