CECHM03 bad temps and GLOD like issue

Hello,

Recently i got my hands on slightly used PS3 model CECHM03, it is a late model FAT PS3 with VER-001 board. It had the Sony seal still on it and no dust at all. It has latest Evilnat CFW on it. I can say it had little use in its time.
The temps are really bad though. I mean it has 80C RSX temp at idle with SYSCON. With CFW fan curve at 33% it has around 60+. So i opened it and removed all IHS both from RSX and CELL. CELL IHS removal is very easy for me whereas RSX is not. Especially this one has almoast no room between the IHS and the ramchips of RSX. But i managed...
Two things happened:
1) I only had significant gain temps over the CPU whereas the original inside thermal paste was bad and all the other thermal paste (outside white ones and RSX inside thermal paste) were still good, therefore i had no significant heat reduction in RSX. But i got the CPU running like 10C lower than it used to be. So currently everything is repasted (Artic MX-5) but the machine is still running hot meaning that needs more than 40% fan to keep it under 65 (RSX) while gaming. Now i have it with the 75C profile so most of the times it runs at about 33% fan speed. It is really strange..i could say the the default cooling system is pure BS, which is..Sony released a product idling at 80C, note it is a late model FAT with 65nm RSX/CELL inside.
2) After the removal of the IHS of RSX i have this weird issue. When you open the machine it practically GLODs. It shows nothing on the screen. You can either close it by holding the power button or with the power switch at the back. What i noticed is this. If you wait like 3 minutes (to heat up a little) and then close it, next time (seconds later) it opens without any issue. If you let it cool it has to pass though the same procedure. You can open and close it normally while it is warmed up (like 60C) though. I have no further issues while gaming e.t.c. There is no visual damage on the board or the ICs.

So please let me know your thoughts, thank you.
 
That glod I assume is related to nec caps. To be sure go and inspect all last 30 errors in SW mode using small letters to auth. Just errlog.
Use uart adaptor.

Thanks so i have to connect this to SYSCON error/PC in order to check what is the error of the issue and then come back to you.
If it is NEC caps i can replace no problem, the thing is i am afraid i had damaged somehow the RSX, either the bals or the mems, i don't know...
I used the "sharp knife" method, so there was some horizontal force applied between the ramchips/package (2 of them not all) and the IHS. But then again i am thinking that if it was the balls underneath or the ram it would not work at all.
 
Hello @vyktormvmpay25 , these are the error logs from the machine taken with PS3 advanced toolset. It does not seem to me that this what we need due to the dates...but yet again what do i know. If this helps please let me know.

Small search this is the AV driver that is problematic or what? I have a dead SEM-01 board, i can source the chip from there, it should be good.

Yes it should be that, if not hdmi, but first thing that AV ic.

i will check both HDMI and AV and let you know, but the HDMI looks good, if the AV ic is the one IC i have in mind maybe i know what happened, maybe a reflow with my iron will fix it.

Why the dates are outdated and in the model it says COK-10D, i mean the errors are valid but all the other info are wrong?
It says the machine is up like 4 days which means around 100 hours of gameplay, is this valid too?
Thanks!
 
I assume using that software tool I never had time to test. No isn't correct about that. Clear errlog and set current data, you may get something like I get in webman sometimes running around 4xxx days.
Test battery to get good voltage on board.
 
I tried to reflow only the AV IC, just some flux and a pass through with the soldering iron, nothing fancy,all went OK in regards to the procedure.
The machine's behavior worsened. Now it opens randomly and not after 3 minutes. So i tested by pressing the metal cover on the back of the RSX side and it opened.
Then after a couple of minutes it showed artifacts and froze. I managed to start it again and loaded a PS1 game and it froze with artifacts again. I think my RSX did not liked the IHS removal...
I will check again when i will have the proper cable for UART to see the errors from SYSCON. At least i will gain the experience.
In any case i can't reball this, i don't have the equipment, only to "reflow" with a heatgun.

I have doubts about the syscon errors coming from the tool
 
Yes it seems as delid made some imperfect connection under rsx from artefacts related.
From here this is hard for repair on usual user without rework tools, I suggest leaving for someone with proper tools. This unit can be saved for someone that can really reball. Reflow is not my advice, usually it kills ic without proper tools.

Yes i know and thanks for the support. Only pitty it was a slightly used machine but that is history.
But that is ok, life goes on, no need for worrying about the PS3 ;)
