Sadly, this repair attempt did not succeed.
The console is serial 02-27430367-2452398-CECHG02.
At the time I was trying the sort of YLOD repair approaches that were circulating widely, but the failed attempt does not establish what was actually wrong with this PS3.
YLOD is a general failure symptom.
Without the console’s SYSCON error history, I do not have enough surviving diagnostic information to identify the underlying fault now.
Modern SYSCON-based diagnosis can distinguish many very different failure modes that all end with a similar shutdown symptom.
So this remains what it was:
an unsuccessful repair attempt.
Stay tuned, though.
We have some mighty successes coming up!
