AV-27220 Chassis # A67, dead, plug in, B+ comes up to 130 vdc, drops right back to 90 vdc. All the secondary standy voltages drop down to a lower value. Changed vertical IC, & caps, as it's very common, & the IC had low resistance on two pins. Found IC 651 had low resistance from ground, at pins # 24, 35, & 19. Replaced IC, same thing, now getting 10 ohms at pin one to ground. It's like someone possibly put a dc voltage to the rear audio/video inputs. Anyone have a schematic, or see this before. Rono.
