Title: Space Invaders WG 19V1001 monitor help
Post by: P-feif on June 25, 2020, 08:37:47 pm
I tried to rebuild this monitor myself. It's the second monitor I've tried to tackle. The first was a WG 4900 in my Ms Pacman and other than the red tones are a little week (tube is just shot) it came out great and works well. So this time was my Space Invaders black and white monitor WG 19V1001. It was having a little trouble with the image fading and it was starting to get some screen curl. Here's what I did...….

I replaced the caps on the deflection board, and the large cap can on the chassis (4 caps in the large can). The monitor ran for about 5 to 10 minutes with a scrambled rolling image. I started to do the set up to adjust all the pots on the deflection board, first up was the B+. Measured at 66 volts, it's supposed to be 73. I tweaked the voltage pot the smallest amount I could and one of the replacements for the can capacitor (it was either cap B or cap C) exploded. I took it back apart and found that the top of the cap was blown open and one of the resistors under the chassis was black in color. Yep I did it good. So here's the question. I really don't want to give up on my Space Invaders game and this has obviously gone beyond my ability. Does anyone know someone who knows how to work on a WG 19v1001 black and white monitor and who would be willing to tackle my mistake? So far the few arcade repair shops near me have said that it's too old and they no longer work on them. Seriously I need help.

Well, I never said how I got it fixed. I found a local guy that knows how to work on this thing. As a matter of fact he does arcade games, security cameras, and hydraulic repair (hey ohms law works for hydraulics too). He fixed my monitor and then my church had a man lift that needed repair. I asked him to work on it with me and between the two of us we fixed it. He donated his time and only charged the church for the parts. I got to be friends with him and I do my best to learn from him.

On to the next game.
