Images were not coming through as an attachment to these emails. I'm hoping when it's embedded in the body these pics will come through. If no pics come through and somebody knows how to do this is let me know.

Found some oozing caps after all. I ordered some new ones and will report back after a little soldering.
I'm optimistic that this is the problem.

Some further information...
The last code on the display befoire te B181F22A was C1802000
After the box hangs, I got the codes off the front panel.
11:
A1003043
14:
H -80P4848 522A
And later I got this scrolling:
H787A.001.DPM0941-P1
9406-520 7450
0000000100000001
43:
A1003043
This one seems to indicate "service processor dump" according to
https://www.ibm.com/docs/en/power11/9856-22H?topic=functions-function-43-service-processor-dump
I video'd the SRC codes as it was booting up.
The last code was
C18020FF - termination complete
And in reverse chronological order:
C1802000 - starting termination
Prior was C1C3C218 - service processor polling spcn
C1C3C210,11,12,13,14,15,16,17,18,200, a bunch of these that all smell like SPCN stuff.
C100911B - normal ipl performed
C1C3C213
C1C3C212
C1C3C211
C1C3C210
C1C3C20F
C1C3C20E
C1C3C20D
C1C3C20C
C1C3C20B
C1C3C20A
C1C3C209
C1C3C208
C1C3C207
So all this stuff seems to be SPCN related before it croaks.
What / where is the SPCN in this box? Model 520 7450 running v7r1. Could this be a power supply problem, or is there a different component?
From this:
https://www.ibm.com/docs/en/power5?topic=locations-models-515-52x-285
I see 'connectors' for other SPCN, but I don't see a reference to "the spcn" on this box / mobo.
There's this:
[cid:image001.png@01DC5623.38205780]
P1-C17 is a 'voltage regulator'. Could this be fried? Is this part of spcn?

I have a small 520 that I bought from IBM maybe 20-ish years ago. It's a P05 processor group - a processor 7450 IIRC. It was turned off for 5 or 6 months, had been running fine prior.
Now it fails during power up with code B181 F22A. I don't think it even got to the point of spinning the drives.
I connected a terminal and tried a manual IPL from the front panel. The twinax card never even talks to the terminal... the cursor stays in the upper left corner.
There is one thread on this list for this. I tried those suggestions. I cleaned and reseated all the drives; cards; power supply; service processor card. One person suggested replacing the service processor battery. No joy. Replaced the service processor module. No joy. Pulled 2 of the 4 dimms (not sure if this will run on only 2). No joy. Swapped in the other 2 dimms. No joy. Put them all back. No joy.
Not sure what else to try. This box is set up for twinax as the console. I've never tried HMC. If there's a quick tutorial as to how to do that, I'm interested. Maybe HMC wakes up before twinax?
The only other replaceable items would be the FSIOP card, the Ethernet card, and the twinax / comm controller.
I'll try booting off a DVD, and a SAVSYS backup tape, but it doesn't appear that the scsi bus is even awake yet.
I don't see any swelled capacitors. Nothing burnt or charred that I can see.
The power supply LEDs are all happy.
The three main fans are all happy. The power supply fan is happy. The LEDs below the three fans show "system attention", otherwise all dark.
If it's the motherboard, my understanding is that the serial number lives on the motherboard, so I'd be screwed since my LPPs won't be licensed.
Looking for a miracle...
