Been looking through this post for 3 weeks now.
Lets just say I made a mistake and only read the first couple pages and then referred to Youtube afterwards and stupidly removed a Tokin without reading further...
Even done the dumb thing of trying some electrolytic caps to replace it as I already had some from a PC motherboard repair many years ago.
Before that mistake I just opened the PS3 up and cleaned out all the dust. Was not to bad. The CPU and GPU paste was not the best though.
So now that I have got up to page 90 I am more educated but need to still read more. I have skimmed through some other pages.
Need to read more about this SYSCON dump, but I think I may have tried booting way to many times, plus disconnected the battery to see the original faults.
Anyhow.
I have a CECHC02 (Australian 240V Launch Unit bought new, we did not get A or B's here as our launch was late March 2007)
It was reballed for a YLOD back in January 2013. It was reflowed unbeknown to me twice before that by the same repairer in 2012, when I payed for a reball. As you could imagine I was very impressed, not, when he told me that upon taking it for the 3rd repair in 7 months after the 6 month's warranty.
I did always have GT6 crashing from the day the game came out.
It worked pretty much OK for all other games all the way until May this year.
My YLOD this time happened mid game in God of War Ascension. It had previously crashed in this game a few times, but I have heard of the game being buggy so I did not think much of it.
At power up I have my YLOD in 1-2 seconds.(before and after removing 1 RSX Tokin, with and without Electrolytic replacement)
The fan does turn on.
I have tested the Power supply and it seems fine. All 5V's are there and so is the 12V.
I have tried the pressure test with no result.
I do have 0.2Ohms between the + and ground on Tokins for both RSX and Cell!!! That sounds like a short to me, but both??? It does not look like I have shorted the rails with my initial solder job.
I do however get a O/P on the CRO in the very short boot time. Only from the RSX as that is easy to get the CRO on with the EMI shield affixed.
I have one with the Electrolytic connected which I did with extension wires and one with just the pads and and no cap.
I will aim to get them up later as I am learning this forum format.
Lets just say they look nothing like previous CRO O/P images posted up with a short. More like ones that have OKish caps.
So I am stumped so far.
So I don't have to read another 100 pages, can someone direct me to a link that explains SYSCON please. Really wpould like to do the dump to see what did break originally and if I have broken anything else since.
Also it includes written instructions.
Cheers
