Previous thread: >>108962331I managed to remove the damaged parts of the board, wire some power to it and talk to the system controller.There seem to be no shorts, however the system can't boot. I'm seeing clock subsystem, AV encoder and HDMI converter-related error codes.# A0092124 FFFFFFFF# A0092114 FFFFFFFF# A0002024 FFFFFFFF# A0902024 FFFFFFFF# A0902024 FFFFFFFF# A0902024 FFFFFFFFBoot log:# [SSM] Bringup Start.# [PowSeq] Error:8302# [SSM] PS0 ng.# [SSM] Cond/Fatal received, msg=24D0.# [SSM] Fataldown Start.# [SSM] Fataldown ok.# (PowerOff State) (Fatal)I did probe the I2C lanes to all of the chips, they seem fine. Maybe it's a power issue, something failing to deliver power to all three of these chips? Or maybe it's just the clockgen power failure that causes failures downstream? I'll look into it later...
*almost ghetto'd me or else I wouldn't post
bruh
>>108974412oh, i forgot about this. so you think you will actually make it work? i saw the bent board in the first thread and thought it was over
>>108974412Godspeed, OP.
>>108974811not unless I can figure out what causing these three error codes to appear. I'm speculating it has something to do with the I2C bus or a missing power rail in this part of the board.
I managed to restore the severed HDMI_EN trace to the relevant Mitsumi voltage regulator and this got rid of the 2114 error.However 2024 and 2124 pesrist. God I wish someone with a known working PS3 could measure the impedance on +1.2v and +3.3v going to the HDMI encoder chip.
