Thanks, I tried what he in the video the same night I said I was taking it apart. The original power supply to the ps3 does not have a variable to adjust the power regulator and the power overload limiter variable.
Since I do have another console the same model I bought a new powersupply for that console, I instead used it on the one I am working on and it does have the variable for both and adjusted it to the "specification" as the one from the video. I still get random shut off
I took today the console apart, cleaned the case and looked over the board. I notice on the very ends where the power supply meets the motherboard there are 6 small tap points on each side on the two very end on either side were bridge. I went and desolder the bridge as well as removed the old thermal paste which was more like thermal rubber from both GPU and CPU and used ultra thermal grease since the product works very well on my gamer desktop holds well to endurance I change it once every 6 months anyways I tried it out once more get the random shut down only this time the console remains on for longer than 6 seconds but less than one whole minute.
I believe next I might take the whole thing apart again and reflow the CPU. GPU... since I do not own a reballing machine I will try to do this using a heat gun and see if that solves the dilemma.
The second console is same model (cech 2501a) but it is from a client of mine, the console fell and broke the shell and power supply but as well as the hard drive and I would have thought the motherboard was ok but trying out the hard drive and both power supply from the other console and the one i bought to replace the one that broke it still shut down after 5 second. So I might as well do the reflow on the clients PS3 motherboard. If all is well and it actually "works" then I will do the same to my console.
I have been doing a lot of research on the subject and why it happens as well as what does the LED code means
I found this
http://www.ps3devwiki.com/ps3/Boot_modiunder the "LED Diag Mode"
I found that I get the same error code as that as the 2501b
GRGR- RRRR-RRRR-RRRR
First section of error GRGR means 1010 or bad startup due to a hardware issue or bad software/firmware update.
including under the "error on boot"
NLOD
NLOD - No Led of Death
Failure in the hardware_init stage. Suspects: Power disconnected, switch off, Power Supply, 12V fuses
Since I used a new power supply I notice the same problem persist. I will have to swap the power switch board next to see if that might be the problem and if last the fuse might be blown I might have to swap it out. I do have a xbox 360 slim with the same 12v fuse so I might be able to swap it out and then test it out. Last option is to do a reflow...
the factor of a bad BD might not be the reason why the PS3 power up and shut down because it does not have a controller board, that is to say the control for the BD like that on the PS2 slim it is part of the motherboard. Therefore if the BD is bad it will still power up the PS3 I actually run this test myself and still got the same GRGR error.
