Hello. I have a ghosts and goblins game in a Robotron cab with K 4900 monitor. After playing the game for about 15 minutes Blackwood start creeping in on the lower right portion of the screen. It never consume the whole screen but about an eighth of it. There was also a horizontal line in the middle of the game that's graphics for the store did a little bit. I replaced all the capacitors and found that eight of the 17 were bad and one of the other capacitors was rated at a 3.3 microfarad when the schematics of 2.2. The capacitor was see 308. I booted up the game and the screen is very dim with some horizontal stationary zig-zagging lines that seem to scrunch up more towards the bottom of the screen. See photos. The screen is also very dim.
