on the fat one that ic is not protected with a fuse, all other power lines are, a bad fuse would cause a normal ylod effect since the syscon ic remains power.
in your case all lights go off, i would say or there's a drop in the power line to that ic due to bad connections, and the ic sort of crashes afterwards because it's not properly reset.
the strange part is that pushing the power button brings the standby led back on.
this is just guessing...lol , this problem might be a pain in the ass.
, what is the history of the ps3, it just happened? or after a downgrade attempt.
Someone sent it to someone else, besides me (first mistake
) for a downgrade.
They got it back and did this.
Thinking it was a brick, because I have fixed some with the same symptoms, they sent it to me to fix.
But the ones that did this that were a brick, stayed green just a little longer before shutting down. And of course those would stay on with the tristate grounded. This one won't.
I can see, that the person who did the downgrade service, must have had the same problem. Because I see where they have soldered tristate to ground. They tried a bunch of different ground points.
I can also see, they must have tried to reflow it also. because I can see where all the flux was applied.
So, they must not of been able to fix it, and was like f it, and shipped it back how it was, acting like it was fine, and not answering the messages this user has sent.
I am curious if it is someone on this forum. Not sure, I will have to ask.
I have inspected the mobo, and can't see anything that might cause the short. I was thinking it would be some solder somewhere it shouldn't be. But just can't see it yet.
I will post some pics. Maybe another pair of eyes will see something I am missing.
