Thanks Ken for the schematic and to all providing tips. Fixes follows; Sanyo DS19390 Symptom: No OSD or Menu, otherwise set ok FIX: Replace shorted vert sync transistor Q881 off pin 20 of IC801 upc. Used NTE85. Sanyo DS19390 Symptom: No signal has raster, injected IF ok. FIX: Replace R412 33k~ off pin 6 of IC101 which supplied 7.6v source. S/M resistor had been wiped off by previous tech replacing IC101.
