some notes on ITC008
Unsolder and scrape off the glue on the circuit board; CV006 CV007
RV001 These are located from pin# 17 of IV001 This usually takes care
of horizontal sync problems. There are times you have to replace all
three to be sure.
Lift one end of diode DL062 (the pincushion shutdown diode) on
the main board near the flyback to see if it then continues to
shutdown. If it does not shutdown anymore, then that would indicate
the small pincushion board on the side was causing it.
ITC008FCS Push pwr button, relay clicks on 3 - 5 sec then clicks off
Check Master AV board. If MAV board is defective, unit will not pwr
up.
