The customer said when the set was last on, she turned it off and heard
a loud crack or popping noise. Then when she turned it on, it was dead.
When the power button is pressed the HV comes up for a half second, then
drops down as a relay is heard clicking off and on. I replaced 3 caps
in the vertical, horizontal and P/S as well as the vertical deflection
IC with no difference. I checked the convergence board, audio outputs
and P/S--no shorts. I also pulled each yoke separately and each CRT PCB
separately with no difference.
Finally in desperation I pulled the RW plug on the signal board and now
the set comes on and stays on with HV and the heaters lighting up. Does
anyone have the SM so they could tell me what plug RW is and where it
goes? I am guessing it is the power for the signal board. I haven't
found any shorts on the signal board yet. The customer was hoping to
get his set fixed for the hockey playoffs which are on right now (of
course). TIA
