EDM 033 – Beep, no electrical energy, standby boot sequence bit very low | GBAtemp.internet

This board has been a bit of little bit of a nightmare however, I’ve modified the southbridge on it primarily as a result of 3.3v from the dialog IC was small, and I modified a PMIC round F5702 just because it was brief, now the EDM 030 is pulling 300ma latest in the middle of standby boot sequence (shut to strange), I assume a daily boot sequence for 1 of those boards is nearer to 350/360ma. It will dangle on 300ma for in all probability 10 seconds or so earlier than dropping to 14ma, at which situation it’ll give me a beep.

I’ve checked all everywhere in the board and I are unable to uncover shorts, I changed the WIFI IC since I’ve heard it ends in equal behaviour with unquestionably no alterations. I additionally taken off the wifi ic from another 030 to examine if it triggers similar behaviour and it does result in the hanging nevertheless it doesn’t goto 300ma, alternatively throughout 330ma, I can say the wifi IC is probably going dominated out.

I’ve injected voltage about F5702 with the fuse taken out, it was pulling like 10ma and I injected voltage across the PMIC that supplies the SSD and virtually nothing out of the traditional there.

Afaik FFFF0042 is early on within the boot sequence as one other individual identified to me so it may be not prone to be related to the APU rail.

Is there one factor else I can examination/study for? Are there different websites I ought to actually check out inject voltage? My best suspect is the SSD controller however there will not look like any shorted caps round it and it receives warmth after I try and capability it on (seemingly regular)
