I picked up a Space Invaders Deluxe upright the other day for $50. It appears to be in really good shape so far. Graphics and paint are all in excellent shape. Dinged upper front corner, needs bondo repair but nothing major. Only a couple (maybe) minor issues:
(I have the front glass and the tinted bezel removed for the pictures)
1. There are these horizontal lines on the screen that move up and down with the aliens:
![]()
2. Invisible first row of aliens? When I fire at the aliens, it's as though there is an invisible first row of them or something. And it seems like I have to hit each invisible alien twice before they "disappear" and then I can shoot what is behind them.

3. Aliens rush down to bottom way too soon. The aliens only move left and right about two rows before all the sudden they just ALL start coming down toward me pretty fast. The best I've been able to do is kill 10 of them before they kill me. Is this a game setting or something wrong with a rom chip?

4. The background is barely visible. The blacklight in the back is working fine, but the background behind the mirror is barely visible as you can see in the pictures. Also there is the semi-circle planet between the mirror and the background that I know has some cool graphics on it but its SUPER dark. Is that supposed to be lit up by anything? It's too dark to even see. I can't seem to find any other spots where a light is supposed to go.

5. Speaker has a load buzz/hum. Does it just need replaced?
6. On the power/transformer board, there are three potentiometers. I was trying to find the volume earlier and stupidly turned each one of those pots wondering if it was on the transformer board for some weird reason (it was hidden in plain sight on the rom board). I read in the instruction manual that an operator is not to change those pots. It didn't appear to mess anything up though... So if I wanted to change those pots to their original values, what should I change them to?
