I had a PS3 slim CECH-3001A with the blackout problem. It would power on, get the green light, then after about 6 seconds, it would power off completely (no red light). I opened her up and then checked for any power shorts on the mosfets and other places near the power connector, all looked good. I also checked the fuses and they were good. I recall some have said it could be an overheating problem. All of the paste was bone dry so I decided to delid. The CELL delid went fine, no damage. I heated up the RSX for a bit and then delid it. The last memory chip at the far corner came off with the IHS! I was very gentle with it. Upon closer inspection, the chip that came off had a lot more thermal glue than the other 3. I decided to hook everything back up and see what would happen. It didn't turn itself off after 6 seconds. I just got the green light indefinitely, so GLOD. Had I not killed the RSX, I think it would have come back to life. In the future, I will use a razor to cut all 4 corners under the RSX IHS to prevent this from happening again.
