I'm trying to repair this old (but well built and heavy :) ) nv-250
vcr for a friend. Power supply was dead; changed open r1103 now unit
operational but display is off. Power supply lines seem Ok, have
subsituted another identical supply and symptoms persisted, so I
suspect something on the mainboard is bad in the AC line to the
display.A schematic would really help!

regards
Ben
