Hi all,

New to forum so please bear with me.
I'm attempting to repair a monitor from a Silent Scope game. The monitor is a Ducksan CGM2907 - the main PCB indicates DS-2907M.

Monitor has no picture - I have already determined that the horizontal output transistor is blown - fortunately, the part number on the transistor is still identifiable.
But R659 is burnt and the color codes are unreadable. I am hoping that someone can tell me its resistance value. Even better, a copy of the schematic would be really appreciated so I can look at the circuitry associated with that resistor to see likely causes of the burnt resistor.

Thanks in advance,
Mike DB
