Armor Attack - Where should i start?

[supergwario]

ok I just picked up an Armor attack and im trying to troubleshoot it. When i power it on the coin door lights come on, I get neck glow on the monitor, the led on the pcb blinks once but that's it. I can't get it to play blind. Any tips would be great. thanks!

Check the power to the board. Check all connections to make sure they are seated properly. Check all socketed chips to ensure they are seated properly. Ensure all cables are there and connected in the correct locations.

The red light on the PCB blinking when you first power it on is a good thing. I steady red led indicated a board failure.

Do a google search on cinematronics repair.

All else fails have Mark fix it @ http://www.cinelabs.com/

Check the circuit breakers on the power supply.

I just got up to the shop and the bottom breaker was flipped I pushed it in a couple times and started it back up, it sounded like it wanted to fire up but then it flipped the breaker again.

it's probably the monitor causing it to blow. Scroll down to the paragraph that starts out " if you are tripping your breakers " and read carefully.

yup, that's it. I unplugged the molex and it didn't trip. Then I reconnected the molex and tried it again and it started up but no sound, I'm going to keep digging I'm just happy to make a little progress!

You need to work on the monitor. I would start with the bottle cap transistors on the black heat sinks and look for burned resistors on the main board.

thanks guys I'll be digging into the monitor next week and let you know how it goes.

I pulled the monitor and replaced R118, R119, R218, R219 with 47 Ohm - 5W resistors i also replaced all 4 transistors I'm still getting the same issue. It's no longer flipping the breakers at least... I have a video of what it's doing but it looks like I'm only getting vertical and not horizontal signals. http://www.youtube.com/watch?v=_5yfhnZh8PI any other ideas?
