PS3 Fault finding YLOD with the SYSCON - First steps and Error reporting

[iKon]

When I took out rsx on dia-001 I expected error 1802, but got 0xa0201b02. Is it something interesting? Because I couldn't find any info about that error

My experince with that error removing an RSX COK-001 == 0xa0202120 COK-002 == [SSM] PowSeq Fail : Detected ! & 0xA0201B02

On COK-002 it can be a bad RSX as well bad connection bad VRAM BAD VCORE bad circuit NET but confirm wise if you remove RSX you will get that error on COK-002

Here is the whole log.

Before unlocking the internal access, a red light flashed again, sometimes stopping blinking and could be started normally. Only once I managed to get a picture on the TV, which was after the internal access was unlocked.

I'm almost sure it's a BGA problem, because I was able to start once with a pressure test.
But I still wanted to know what the error means - 1214

Just ran into this replace IC3101 near SB if you have no shorts possibly power issue as well tied to net check Q6309 me i had no 3.3 volt on one of the legs of !C3101 do to short replaced IC now 3 legs have the 3.3v but like i was saying Q6309 also on wiki they filled this info in so that wiki note is what solved it but i checked here to as well thought i would update thread with result
