EDM 0-10 - Beep no Power. F7001 Blown + Short F7502 area

EDM 010 beep, no power
F7001 blown + short on the right side
F7502 area: 2 shorted caps

Does 5V pass through there? I injected 1V but I don’t see any hotspots. I’d like to increase the voltage, but I’m not sure.
Fuse F7502 OK

Sorry for the quality of the photo, I took it with my phone.

Your 5V_ACPI_SOC line is shorted. This the right side of fuse F7001 and the both marked caps on your image.

There are ten chips connected to this line i would check. Orange markings.

Yes, it does. I have shorted capacitors along that entire line marked in orange. Do you recommend injecting up to 5V and checking for hotspots?

I wouldn’t recommend injecting more than 1V in this line. I would increase the amps to 3A.

But I guess, if one of the 0.75V or 1.8V bug converter is broken and passed the 5V input to the output, the damage would be already done to the SoC.

I was lucky.
1V - 2.5A, this guy popped up.
Removed it, short gone.
I’ll replace the F7001 fuse and update you.

Similar case. F7001 blown
Right side short.
I injected 1V - 2A on the fuse pad right side and with a thermal camera found a cracked capacitor that I removed (PHOTO) and haven’t replaced yet. (CERAMIC CHIP (22MF)
Short gone.
I replaced the fuse, but nothing, beep no light

I measured 0.5V/0.8V on both ends of the fuse.
What could be causing it?
The UART still gives 8087003 and 8091002, but there are no shorts anywhere in the area.
Does the capacitor that I didn’t replace have any effect?
Boot sequence: 0.055 and after 10 second 0.009

Upper pad 5V
Lower pad 0.4V as at the ends of the fuse

For testing the missing cap shouldn’t be an issue. But for propper working I would put a new one back in place. (0805 47µF 6.3V X5R)

Different reading on both end of the fuse = bad/blown fuse.

This explains the both UART error codes, which are pointing towards power issues at the SSD controller.

SOLVED.

The fuse pad was partially damaged, perhaps from the previous repair attempt (the console came from a lab).

fixed the pad, fuse OK, and finally booted.
Stuck in safe mode with CE-120640-3.
Reflashed the BIOS from a working dump, and finally everything was resolved.

F7502 right side short (fuse blown), found a guy heating it.
Are they still 0805 47µF 6.3V X5R as the value?
I can’t find the reference.

Those are 22uF_6.3v_0603
