First post ever... Dig this forum so far!
I recently acquired a Burgertime cab with a Big Event Golf conversion as my entry into arcade restoration.
Problem 1: The game had monitor issues when I first tested the unit. The screen showed mostly red and blue colors and not much else, so it was impossible to play though the screen looked centered and still. I started twisting and turning knobs on the monitor to see if I could adjust it, but quickly realized something had to be damaged or dead. The monitor looks as though it was found in an alley, but the rest of the cab looks great. I can tell someone put a cap kit on it not that long ago too. I discharged and removed the monitor, and repaired a sloppy info cable to the monitor (colors etc…). The colors are now mostly green and nothing else and extremely out of adjustment. I could barely get it to stay still in the middle of the screen without looking like an oscilloscope. It's a Wells 19k4500. Money is tight lately as there are threats of layoffs at work soon, so I'd like to repair it rather than drop a bunch of money on a new or used one. I downloaded the schematic, but nothing else seems to be available.
Problem 2: The switching power supply (Peter Chou) seems to come on when it pleases. It looks brand new, absolutely no sign of dust etc... It shows 115V across the two 115V terminals, and when it comes on it stays and works fine supplying power at the proper levels i.e. 5v, -5v, 12v and so on until I switch the unit off, then back on and it won't come on. It's hard to trouble shoot the monitor when this happens. Does it mean it's bad, or is there a fix? My first thought was that the PS may have an onboard breaker that resets when it cools down indicating a short, but I don't think this is the case when it will work sometimes and allow game play etc.
I'm thankful for any help you guys can provide!
