Hey all [Ken, Dave aka Dokert]
My 4901 odyssey continues. To date I have replaced the fly, and hot. I'm using Fromm's flowchart and have hit a dead end.
Pull out your flow chart and follow me if you will:
Start here: Blank screen -> yes
Blow Fuse F501 -> yes -> replace HOT Q352 -> retest
Start here: Blank screen -> yes
Blow Fuse F501 -> no
Check the regulated power supply at resistor R503 ( that's the 150 ohm, 15 watt ceramic resistor) The terminal closest to the fuse should be measure +130VDC -> low
Check the voltage at the other end of R503. It should be around +145 VDC -> 0 VDC
R601 may be open ... R601??? Where the @#!% is R601???
Hey thanks guys...
