Re: Dead 7603
Thanks, everybody, for your help. Here's where I am now: Primary nottoggle quoted messageShow quoted text
open; it measures about 3 ohms with the on/off switch on (obviously open
with it off!). Poked around P1171 and measured DC voltages. -50V,
-15V, +15V, +50V, and +130V all within spec. +5V measured 4.46 V, when
it's supposed to be 4.85V minimum. Hey, the power light is lit now!
Must have been a bad connection that I reconnected when moving the power
supply section back into place. Checking ripple and looking for shorted
tantalum capacitor(s) on the +5V rail next.
