First, about me: First post--enough electronics experience to know the basics but before now, little monitor experience.
Have a WG 25K7193. Recapped when I got it and it worked good for a couple years, then died. Blank screen. Then the flyback went. Got a cap kit, flyback and hot from Bob Roberts. Installed all and back to just shutdown.
Started reading here and got Randy Fromms flow chart. I have neck glow. I have sync. Turning up the screen control I get horizontal scan lines so following the chart, I checked b+ = 129v & 155v
OK, so further reading I've pulled r84-86 and they checked out fine. R103 good, R301 good. Pulled C55-good. Found R89 loose and resoldered. Reflowed everything. R101 seemed loose so i got that down too.
I haven't pulled D10, should I? What else? I'm really getting frustrated... Thanks for any guidance and don't be shy about details on how to "check" things 'cause other than some obvious stuff (diodes, resistors and the like), I don't know a lot.
Thanks again, David
