Techs,
Push the "ON" button and only a relay clicking, on then off immediately,
pushing again does nothing, pushing again does the same relay clicking
thing. Found shorted C553 (.33uf/200V) in horizontal circuit (replaced). HOT
is OK. Found Q606 (C-E shorted) in +B regulator circuit, replaced. Found
baked E-Cap C502 near vertical output heatsink, replaced.
Any thoughts? I'm going to seperate and load down (light bulb) the +B to
confirm regulation, if OK I'm tempted to bypass the relay and slowly crank
up the AC while monitoring the current (+B inline with light bulb). Should I
do this? Any suggestions would greatly be appreciated.
Thank-you.
