On the large main signal board, replaced all the regulators on the
common heat sink: # on parts: SI3120C (12V), SI3090C (9V), SI3050C (5V).
The 12Volt reg was shorted dead. Replaced others as precaution. Now set
powers up with filaments and HV.Advance G2 , look down the CRT's and
see a slick raster with no OSD,Sound or video.
This has been a project in patience awaiting the parts orders. Running
out of time.
Anyone have a PDF of this unit? A manual for this older unit? I assume
it's a video problem at this point.Or a missing voltage at least.
I'm blind without a schemo- Customer needs to wrap up this insurance
claim soon.Thanks in advance,
Phil Bader
