I have a post on psx-place for this but thought I'd try here as well in case anyone has experience or the schematics or any kind of help. Here's the original post from psx-place:

Hi, so I bought a YLOD Fat PS3 as I wanted a repair project and thought it would be a good way to get experience. I was able to solder to the RX, TX and Diag pads on the COK-002 motherboard and was able to get external access and retrieved the codes. I haven't powered it on beforehand so these should be the last ones. I did try to get internal access immediately after but kept getting scopen response invalid and auth invalid even though the wires hadn't changed. I will try that again though. In the meantime, these are the codes I have from SYSCON:

My thinking is that 2110 is the issue and causing the 1001 error. I don't know if 1004 is anything to worry about with it just appearing once and I'm not certain 1002 is a major issue, again due to its infrequency. Does anyone have any other thoughts and maybe some ideas on what to check next? Any help would be greatly appreciated. END
I have since added this extra information from last nights crack at it:
To add to this, I tried to get internal access again but still received the message of ‘scopen response invalid' and ‘AUTH invalid'. I tried reconnecting the Diag and TX but no luck. I've since desoldered them so I'll try soldering them again later. I have replaced the thermal paste and assembled enough to test. I get fan spin then it immediately turns off and I'm left with a red blinking light. It seems to be about 3 seconds before the yellow light flashes and the beeps appear. I'm stuck at this point on what to check next. I have followed @RIP-Felix guide and had success up until trying internal access.
Based on what I could find about 2110, I could do with the schematics to locate the 5V_MISC and other components mentioned plus some guidance. If there's something else you can think would be worth checking then I'm all ears. Thanks in advance. I can provide photos and videos if required.
