Need your help once again group - set turns on, high voltage comes up,
get raster, and about 4 seconds later shuts down, but green power LED
on front stays lit. Can power off and back on, and the sequence
repeats. I've checked almost every cap, diode, resistor, and found
nothing wrong yet. Tried freeze spray also, but it doesn't seem to be
temp related. I suspect a shut down circuit, but I don't have the
schematic to troubleshoot. The B+ drops about 7V after power up,
otherwise is pretty stable. Anyone have experience or knowledge on
this particular model or problem? Thanks for any help.
