Title: Stuck in boot
Post by: Delma on April 19, 2022, 10:42:46 AM

This machine was working fine. Now it's stuck trying to boot. I went over all the wires and everything still seems to be plugged in where it should. I get the AVP screen and sound. Then screen goes black and starts over.

Please see pics

Sounds like a bad, failing power supply unit.

Try swapping it out with a known good one.

Thanks. I'll give that a try.

Tried swapping with known working power supply. Same issue.  :Scratch-Head:

Ran diagnostics test on it and everything seems fine.

Did you try replace the power supply on the mpu, not just the main power supply?

replace the ribbon cable from the pci card to the backplane.

I don't know how good you are at taking the cpu board out of the case.  Remove it and remove heat sink on main processor.  Heat transfer grease drys up on these over time causing over heating and rebooting of these slots.  Also check if fan on main processor is working.

I good rule of thumb is to determine the extent of the reboot.

1.  If you do not hear the POST beep more than likely its a software issue or issue related to peripherals (including the IO card)
2.  If you hear the POST beep than it is usually related to the CPU side.  Check processor, power supply, connections, etc.

Copy that. I have a working MPU in a machine that's not in service. I can use that one for this machine. I'm just very unfamiliar with the diagnostics of this machine. I wouldn't know how to clear and set back up. I have ekey 7 and diagnostics key but that's just in case I've had to use it. I think I used the ekey to change the denom for both 25 cents and 1$. That's all I've ever had to do.

I spoke personally with Delma and she said the problem ended up being the MPU.
Her tech swapped it with an extra one they had, and the machine is working now.

I've marked this Topic as "Solved" :cool_thumb_up:
