Need advice on cleaning up RGB on NA Model 1 MS
Looking for some expert advice on how I should proceed on trying to remove the red vertical jail bars. I have a Model 1 NTSC Master System motherboard 171-5379 and RGC cables with the built in resistor and I’m getting red vertical jail bars. Information online says that this board runs RGB straight to the video out, and that it needs to be amplified through a special SCART cable that was only produced for French MS’s. I do get an otherwise clean RGB signal other than the jail bars and the mobo seems to be fully populated and not missing any components in the video processing chain, unlike the French counterpart. All capacitors seem fine, but the RF modulator seems to have capacitor juice underneath it. I am assuming there are caps inside the RF modulator. Would removing it possibly fix the jail bars?
