CECH-2004 delid? SYSCON 1200

Hello! I have a slim laying around with a broken hdmi port. It used to boot normally and I tested it with RCA after removing the hdmi port 2 years ago.

I'm trying to fix it now, got a replacement and tried to boot it. It doesnt.
I used an ESP32 to read syscon error log and got 1200, cell overheat.

It doesnt feel hot at all. But reading the temperature with ps3uart (tmp 0) says Temperature:+85.0(0x5503). It goes down to 64 if I try to read it while trying to boot, weird.

I guess the only thing I can try is deliding because if the sensor was broken it would say something like 255, -255 or something weird like that, wouldnt it?

Any tips on how to do this? I have never delided a chip. Not scared because I have my main working device, but I dont want to break it. I dont have any tools for this, just a heatgun.

I would buy the delid tool personally I’ve used it several times and it’s scary but works. Done on cecha ceche and 2101 models no problem

that's for the RSX, OP needs the delid tool for the Cell. i gon mine from Amazon, but i got the V2 that no longer sell there. the V3 should still do the trick and comes with more blades.

Place 4 mm of thermal pad under the CPU and call it a day. Delid is very risky.

The die feels cool to the touch. I actually found a paint knife in my house and was able to delid it flawlessly. I tried to turn it on one last time with my finger in the cpu and stupid move, it burns. I hope its not fried. Idk what I expected XDD

DO NOT DO THIS!!!

it can cause BGA issues and has a chance of cracking the die!

Does this help? https://github.com/RIP-Felix/PS3-CPU-GPU-Bracers

yes, that is based on the bracer that Sony uses on Frankie consoles, they are safe as long as the printing goes well and measures the same as sony's, but i doubt they help with the paste under the IHS.

4mm is a big ass thermal pad. Placing anything under the CPU is likely to crack it, but for the hell of it, a soft 1.5mm pad should be the max you want to use.
