      Have you tried swapping out the hard drive and CD rom?...

      If this still doesnt work with new HDD - then you should also try to bench the board with nothing attached, except the RAM, CPU, Keyboard and Screen.

      You should also treat the keyboard as suspect incase it is faulty and sending some incorrect signals to the board, so remove it and try to boot the machine again...

      please report back with findings if at all possible...

          Maybe its overheating and downclocking the cpu ery low?

                  Sounds like a dead/dying hard drive to me. Swap out the SATA HD and try an OS re-install from scratch.

                      I agree.
                      A dud HDD is a definite possibility.

                      A dud drive and no drive can throw the same symptoms.
                      Try it on the desk with a known good drive.

                          by Woodsworth
                          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:
                          START
                          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...

                          Problem with LG Plasma 60PM6700 - Random power downs
                          by theone111
                          I have an LG Plasma TV 60PM6700 for the past ~12 years.

                          In the last ~3-4 months I have been having some issues.
                          1. Problem: It started with random picture disappearing (sound still worked).
                            Frequency: Happened about once a week.
                            Solution: Had to turn off TV wait a few seconds before turning it on again.
                          2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
                            Frequency: Happened about once a week.
                            Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.
                          3. Problem: TV shuts down

                          by Zeonalbasta
                          i have a problem with thinkpad X1 carbon gen 2 "LMQ-1MB 12298-2 48.4LY26.021"
                          The laptop was turned off because the MOSFET was not transmitting voltage. After checking it turned out that the gate pin on the MOSFET was the problem, because it was producing an inappropriate voltage. and it was discovered that the problem was with the Think engine, so I decided to reprint each pin, and finally the mosfet could work properly. However, there is another problem, even though the voltage has been supplied to the laptop, it still won't turn on, there isn't even an LED indicator. After double...
