I bought a taito cabinet with Mr. Do board installed last fall. When I plugged after I got it just buzzed so I put it away for the winter. I was messing with it and reseated some cables and it doesn't buzz any more. When I went around to the front I just get a blue vertical line. I dropped a quarter in the slot and was now able to play blind. I'm very new to arcade collecting I have built a few mame cabinets but this is one of the first dedicated cabinets I have. I looked all over the monitor chassis and I was unable to find a model number. I attached a few pics hopefully someone can help identify the monitor and point me towards a solution.

Thanks,
Brad

Wiggle the daughtercard with the 3 pots on it. See if the picture comes up fully. If so, go to step 3.

Well, start with the basics:

1) Make sure the green and yellow wires are connected to the yoke.

2) measure the yoke tabs where the green and yellow wires connect (two middle tabs) and see what reading you get.

3) Recap, reflow, etc the entire monitor. Very common for the pins to the daughtercards to have bad solder.

4) Try testing again...
