Hello everyone I am having a very frustrating issue on my roadshow. So everything was working fine when one day the machine just rebooted itself while in attract mode after being on for about 2 hours. This continued to happen ranging between 5 seconds to about 1 minute between resets. The DMD is showing random garbage as well.This was not caused by hitting both flippers together but rather just when the game is sitting as in the video... So far this is what I have done.
Checked the 5v on the board and it measures as it should.
Replaced BR1 & 2 as well as C5 and C4 caps.
Jumped the legs on the Thermistor. No help.
Checked and reflowed solder on all male pins on the Power driver board.
Switched the DMD with a newer one that I know is not gassing out. (remained garbled) I should mention that I bought the machine with a rottendog DMD board that the previous owner said was about 2 years old..
Disconnected all the connectors and ribbons from the CPU board except for J210 and tried watching the 3 leds... Everything boots then resets on the cpu so it seems as the problem is isolated to that board correct?

Anyhow I am really stumped and tried looking through the forum/internet for anything remotely close to this problem. Anyone have an idea? Thanks for any input you might have, anything is helpful!
Here is the video.

Also I forgot to mention that the game is a reimport if that might hold a clue.

Thanks for the advice. I did actually do this with the exception of the ASIC-89 chip. What seems even more odd to me is the strange almost surging towards the end of the video

Bump for some advice from the evening shift hopefully

Yea thanks you guys I have pressed the ASIC and checked the wall voltage... Everything tested good with the voltage and I have 4 games on 1 beefy power strip (all with 100% LEDs ). These were one of my first suspects. I should also mention that I have tried multiple other outlets and checked for shorts under the pf and close to the sides as I installed mirror blades on the game.... I thought something was shorting against the metal blades. Thanks for your responses but any other suggestions? I have basically been following the wpc reset guide online. I kinda feel like I need to send some boards out but at the same token I feel like tracking this issue down would be a major confidence booster

Thanks you guys. No sparks or anything but I will go ahead and repin all the male connectors and switch the female idcs to molex and report back. Still pretty concerned more about those flickering power surges towards the end of the video. Have you guys seen this before? I have seen resets obviously but not like this.

So update. No burnt pins or connectors. Reseated all the roms double checked all connections etc. still measuring a solid 5.05 v and 12v on the board and pin 32 of the game rom is getting 5.04v. Now when I turn of the game d19 and d21 stay lit and the CPU will not boot. When I disconnect everything but the power then I get a single bong but d19 and 21 still stay lit. Maybe a chip problem somewhere? I think it's time to send the board out to someone. Any suggestions?

Hey sorry for the slow response I ended sending the board to Clive and he worked some magic. Game has been pretty good over the last month with an occasional reset which I am now further looking into. I'll report back soon
