Sanwa model 29E31S color video arcade monitor 29".
Symptom: Has raster, but no video or very dark video
Cause: Found several bad solder joints. Check soldering closely at electrolytic capacitor C409 (470 uf @ 16 volts) on main board and at the flyback transformer. Check solder on "SCREEN" wire connection on the neckboard.
Excercise caution around connector P913A on the main board as wires can be accidently be pulled out of the connector housing very easily.
