Ok I know this is an old one, but it is for a large arcade machine, and such must be fixed

I am looking for a schematic, or if anyone know what resistor goes on the board

Power Supply Board

Model: 935C31801 and it is R913 that I cannot read .

any help is much appreciated

It might be best to get a schematic for this!

I'm thinking your IC901 could be burnt out too.

Check diodes D903, D904, and D905 please! Also check C918.
