Repair of 17" KDS XF-7P CRT Monitor

KDS (Korean Data Systems/Proview) CRT monitor
Model: XF-7P, Mfr Code: DFT Rev No: 00, Chassis No: C718, Mfr Date: July 2001

Could somebody please provide me with the component values of C503 (?nF / ?V)
and R509 (wire?, ?Ohm / 2?W)


Both components are located just below the left-hand corner of transformer
T501, which is on the right-hand side of the PCB about in the middle.

Due to failure in production they touched each other, which eventually led to
their thermal breakdown, rendering their values unrecognisable.
