ES1 A2 Namco PC not powering on fully.

[Opelspyder]

I have a Tank! Tank! Tank! That the PCs have been cleaned and working great for over a year. I did have some issues with this one side, but reconnecting component cables seemed to correct it. That was until the other day when that one side wasn’t sending signal. Upon further investigation I found the fans of the PC were not running, so I pulled it and figured I had a bad power supply. Got another PSU and same thing, so I tested both PSUs and they are good. When I plug it it up, the fans flicker, as if they for a split second received power. So reading up, it’s like the computer board isn’t turning in and there is not a manual power switch, but I feel this is the issue. I’ve read in posts that the Motherboard header you disconnect it and just the bottom two pins to manually power it on. But this isn’t working. I see it has some jumpers, so I removed and whilepowered up, I tried with no results. Am I not looking in the right place?

I removed the lower jumper and tried it manually, but maybe I’m not following the exact procedure. Green light on the board and the output board. I feel it is that simple, but maybe I’m not doing the procedure correctly. I take out the jumper, power on the unit, jump with a screwdriver the two terminals, and nothing. Plugged the jumper back in with no power, and then tried and the same

from this thread

unplug the header that also has the power switch on the board and manually start it with a screwdriver, it's the lowest 2 pins on the header.

From your first picture, you're just showing the dip switches and no headers? shouldn't it be the one with the grey/blue/purple/green/black wires from your 2nd pic?

Check RAM and CPU. A PC won't power on if they're faulty.

I originally thought that that was the header in my second picture. It has a bracket to hold it into place, and I did the same procedure on that as well, even looking online for what is generally the power button connections and cut an old connector and wires out of another PC. But still nothing. I reseated the RAM, but haven’t messed with the processor. What can I do with it but just try to reseat it? Clean and put more thermal paste on it? I’ll try that, I probably have some Ram I can swap out. I just don’t want to start robbing stuff from my other unit (I have two being a (Tank! X2) and then have both units out in me

I would replace the ram from the working unit. Then if needed, do the same for the CPU.

You need to rule things out.

Okay, so I pulled my other PC, swapped the RAM, no change. Put into other machine and it starts up just fine, swapped the PSUs and still nothing, put into other machine….other PC still working. I don’t see any swollen capacitors on the MB, do you think I just have a dead Motherboard? Anything else I might be able to check? I see some MBs on eBay, but all coming from China

whatever you do, DO NOT SWAP the hard drives or connect them in a windows machine!!

Yeah, I know the hard drives are encrypted and such, I once tried to copy them on a SSD, I read about a guy figuring out how to do it, but again, not my issue. I guess I’m looking at a Motherboard?

It does sound like a faulty motherboard.

Why can't you swap the hard drives?

Connecting a ES1 hard drive to a Windows machine will result in the Disk Signature field being overwritten with random numbers. It should be blank. You can fix this in Linux (a live USB installation works just fine). You just need to write zeroes in place with a dd command.

so I had similar issue and those 2pins to make it power on is in here ( red circle there) rather than your first picture ( I try use my picture to show ):

This fixed it! Thank you for pointing out the correct plug. Now I’m hoping it will fully boot
