Paperboy Restoration - Any Ideas?

--- Quote from: RayB on July 27, 2008, 02:20:38 pm ---We need photos. This: "the screen is jumbled and the the speakers hum." could be interpreted many ways:
1. The monitor is fine, but the game board is outputting "garbage" graphics.
2. The monitor sync is off until it warms up (game board could be fine).
3. Both are wonky. This is not likely though, since the monitor is powered from the AC isolation block, while the game boards are powered from the regulator board and big blue, etc...

4. Ground fault anywhere in either loop.
5. Dead power supply filter caps -> AC ripple.
6. (most likely) Badly corroded or broken connectors, both on the boards and the harnesses, because nearly every Atari cabinet I've ever worked on had to have these refurbed or completely replaced before being anything close to reliable. Note that this can directly cause 1, 2, 3, and 4 or any combination of them.

Okay. Here is a pic of the screen at power up. Sorry it took so long. I need a new camera. BTW, it never "warms up" as the seller said. It pretty much stays like this, Although the screen eventually stops the ripple effect that you see.
Any ideas?

Board issue of some kind. Start by verifying voltages on the PCB. If they're off, you need to get that working first. If there are other things going on, you won't know until this is satisfied at the very least.
deathbot:
Okay,
I am sure someone posted somewhere in here, but I can't find it. What is the best way to clean the connections? Alcohol and q-tip? Compressed air? Also, as far as re-capping the monitor goes, I don't see a name on it, but there is a serial number that begins with WG. I assume that is Wells Gardner. Would that mean I could just order a WG recap kit? Does anyone know if it comes with instructions?
Thanks again for the feedback guys,
deathbot

you can start with a pencil eraser... then move to alcohol if needed.
Getting a pic of the chassis on the monitor would solve the monitor id problem..
