KDS XF-7e monitor
 

I have a monitor with a burned resistor, R509. Anyone have a schematic
of this model that can tell me the value of the resistor? Anyone know
a web site that has a schematic for this model?
Thanks.

Where does one get schematics for monitors nowadays? Is there anything
similar to the old Sams Photofacts?

I've gotten lucky here befo

[I didn't see your model listed.]

Bob, That resistor is 22 ohms at 1 watt. It is in series with C503
(0.047/400) and they are in parallel with the transformer nearby. I
think it is used as a snubber circuit. Hope this helps.

Thats it! Thanks a bunch - thought I'd have to trash it because of
..25c resistor. You da man!

Pete,
I noticed you had a post about this same circuit in another monitor.
Appears that the resistor shorted to the cap through the coatings. I
replaced both, paralleling two 47ohm 1w resistors, giving me a 2w
combo. So far it's working & not heating up. Thanks for the help.
