Hello! Long story short.. I purchased a 2nd hand 30xxA and it was slow and was shutting down randomly.. upon opening it up.. I saw that the thermal paste was expired (had to be replaced).. and the two metal plates that are above the gpu and cpu were tightened upside down such that the cpu/gpu were not making proper contact and had no weight upon them (this was, I believe the reason of random shut downs) now after placing it properly and changing the thermal paste.. the ps3 is showing no sign of life ... it turns on with a green light, no hdd light.. no controllers connecting and the fan is working.. it turns itself off after a minute or so with a click sound.. Now what are my options ? I don't personally think that it's dead completely because I believe these models were redesigned to last longer anyway.. every help is appreciated. Thank you!

It’s hard to tell what exactly you’ve missed, but by the sounds of it the tension on the mounting screws might be too low. The CPU and GPU in the PS3 are pressure sensitive and will refuse to complete the boot sequence if they detect that the heat spreader is loose. You can counteract that by applying some washers under the mounting screws, but usually that’s not necessary and good old elbow grease can do the job. In addition, if the console was pretty old (which it is at this point), the connectors might be a bit dusty and contact might be spotty unless you reinsert them a couple of times to get past the oxide layer. I say try tightening the screws around the chips, and if that fails, disassemble and reassemble - there’s no reason why it wouldn’t boot just from disassembly unless you damaged the board while you were at it. Trace your steps back, see if you missed something.

Okay after reopening it and adding some previously missed screws.. the ps3 does turn on and won't turn off until I myself hold the power button for about 5 seconds or so but there's nothing on the screen. The hdd light does light up and blink during start up but controllers still don't connect

Sounds for all the world to me like you’re in Safe Mode and not outputting to the correct display out (HDMI or composite?). Check if a controller will connect if you hook it up by USB. If yes, you’re probably in Safe Mode, check the other display.

I was wondering the same but as I mentioned, the controllers do not connect. I haven't connected the BD drive, does it make a difference and what about wlan/bt cables, do they make a difference as well because I suspect I have mixed them and connected the wrong cables.

Okay, let’s start with the basics. Hook everything up, correctly. If you have any clean spirit available to you (like isopropyl alcohol, or vodka in a pinch, anything without flavourings and colourless with low water content) you can clean up the connectors with a damp q-tip. Reassemble the console correctly, disc drive et all. Follow the iFixit guide backwards, if you’re ending up with spares, you didn’t do it right:

https://www.ifixit.com/Teardown/PlayStation+3+Slim+Teardown/1121

Try to boot the console in Safe Mode using the appropriate key combination (for Slims it should be just holding the power button until you hear the second beep) and connect with the last display method you used - if HDMI doesn’t work, check composite. Be sure that the heatsink is tightened on correctly and you have fresh paste covering both the CPU and GPU heatspreaders. If you feel the pressure is insufficient (shouldn’t be), use washers or gently press the heatsink down just for a test boot and report back. This sounds like an assembly issue or bad contact, you’re not getting an YLOD and the console is trying to boot, just unsuccessfully. It’s hard for me to diagnose which step is messed up because I can’t see it. :P

You may well of pulled the Heatsink off with too much force and pulled the bga connections off partially,very easy to do on cech 3000 onwards models

anyway to confirm this is indeed the case ?
This is a PS3, the cores are protected by the heat spreaders (which were apparently attached wrong on your first inspection?), the chances that you chipped them are next to nothing unless the system was poorly delidded and damaged in the first place. Any chips should be visible to the naked eye once the cores are cleaned, remember that you need thermal interface not just between the heat spreaders and the heatsink, but also between the IHS and the cores.

    assembly is actually great, gets you to run everything about 80% faster than C massaged code
    Gift
  • Coto @ Coto:
    assembler syntax is dead easy, but "how to put pieces together" logic requires to have in mind the original idea, and the CPU layout, and that's like double the work of C stuff. It's best to write C first, add some unit tests, then go assembly, then run the unit tests

  • The Real Jdbye @ The Real Jdbye:
    it can run faster than compiled code, but modern compilers are really good at optimization and you need to be even better at assembly to do a better job

    with that all your assembler base will actually work

  • The Real Jdbye @ The Real Jdbye:
    syntax is easy but the code is hard to read, you can't look at a piece of code and expect to understand it without looking at all the code around it to see how it all works together so it takes much longer to read the code, it takes longer to write it too because what might be 1 line of code in C might be 20 lines of assembly
