an Arcade Route op brought this in today- DOA
looking for a schematic as there are a pair of resistors in the SMPS burnt beyond recognition.
startup caps are bad as well. but, of course, can identify those .
no joy with any search engine .
anyone ??
TIA

These are found on Neo 29 cabinets. Might get you some more info.
I have an operator's manual which includes some troubleshooting flowcharts and other info, but no schematic. It's also in Japanese.
Would you like me to scan it in?
I can also get you pictures or measurements off known working units if necessary or if you have stuff burnt beyond recognition.

tnx
but, doubt that the chart will be of any use . even in Engrish
the startup caps were each several hundred ohms of ESR
the resistors in question are also in the primary side and part of a timing network.
should have posted ref#'s.
will try to so do in a couple of days

Crap, I just noticed you said 25FS2, not 29FS2.
I only have the 29". I have a friend with the 25" version, though, so I can probably get info, but it may take a while as he's super remote and generally uncomfortable with working on monitors.
Of course, if it's similar to the 29", what I have may be useful enough. Probably not the case for the timing section, though :\

the reference numbers to ID are
R905 and
R906
edit:
customer brought in a working unit.
of course, same resistors burnt. :badmood:
measured as
R905 4.7 ohm .5W
R906 15 ohm .5W
replaced both with a 1 Watt of same resistances, along with
C902 4.7uF/160 V replaced w/10uF/250V 105 degree
C906 2.2uF/160 V replaced w/2.2uF/200V 105 degree
works fine now ;D
