Hi everyone, I hope someone can help me. I'm gaining experience in the repair of PlayStation, especially in the PS3 with YLOD. I have already fixed for hobby 2 fat (CECHG04, CECHL04 and a slim). Now I have 2 fat CECHC04 in my hands, very interesting because they are backwards compatible with PS1 and PS2 games. With both I am at the same point with the Syscon diagnosis and consol in YLOD (within 4 seconds).
First reading of Syscon was:

RIP-Felix (very nice person and video and incredible knowledge of PS3 repair) alredy told me (as answer to my comment into his video) that RSX reflow could not be 100% succesfully.

A big THANKS to RIP-Felix!!

So now I need to fix only A0801701
If not succesfully can someone explain why A0403034 and A0404412 are disappear and the console is booted (state 80)? or it means that, yes it is booted but as soon as BE start to comunicate with RSX for advanced steps, the RSX status discovered is "not possible" (sorry for my english)?
Anyhow I'm open to additionak feedback on how to go ahead (complete reball?)

I'm having the exact same problem, on a CECHG02 board. I read syscon, got A0801002 consistently and replaced one NEC/Tokin cap with 4 470uf tantalums. This has worked on other boards in the past for me. RSX voltage is a steady 1.3v. CELL voltage is a steady 1.2v.

One thing to note, in the process of removing the NEC/tokin cap, I did accidentally knock off a small capacitor just to the top-right of it, from the perspective of the power button being at the bottom right. I soldered that back on in the correct orientation, though.

If anyone's seen A0801701 and fixed it, would love to hear how.

Cheers,
 
Actually I solved it! In my case, the NEC/Tokins and the cap I knocked off were all red herrings. This console always had this issue, it just wasn't able to get to boot state 80 because of the NEC/Tokins, so when I fixed that, this error appeared.

Reading through this page (https://www.psdevwiki.com/ps3/Syscon_Error_Codes) I found a line on this error, and it was saying the solder bumps under the CPU's die itself, between the die and the chip, could be cracking while the console is on. To test this theory, I got some rubber washers and stacked them under the heatsink tensioner. When I powered it on after doing that, boom it worked.

Obviously this isn't a fix, it's just a diagnosis that was successful. So pretty much this console needs a new CELL if I want to sell it on (ha!), otherwise it's good for spares.

Having a pretty similar errorlog with a CECHK-04. What do you mean with "To test this theory, I got some rubber washers and stacked them under the heatsink tensioner". I can't figure out how to do it why should works. Thanks!

Absolutely. So I got a 2mm thick rubber washer and a 2mm thick nylon washer, stacked them so the rubber was touching the back of the board behind the CELL (not the CELL itself, but surrounding it) and the nylon washer was stacked on top. I then put the RF shield over the top, and tightened the heatsink down with the clamp. Similar to the fix Sony did on repaired consoles for early model CELLs.


If you're looking at it side on with the console lying flat, it would look like this:

Heat sink clamp
RF shield
Nylon washer
Rubber washer
Motherboard
CELL
Heat sink

Perfect explanation, thanks. The fact is that I can't figure out why it should works. Is something "electrical" (like a short) or physical (pressure at which the chip layers are exposed). It's a pretty bizarre fix!
