Re: Ps3 shutting down
Could use a little more details, like full model number of the PS3.
If it's a "phat" one, issue could be the GPU, the PSU (particularly if it has a Nichicon-made PSU), or those NEC-Tokin caps (which many of the "phat" PS3's do.)
Sometimes, those "phat" PS3's also like to blow a fuse on the board, but I've only seen that once. Most other times, it would be one of the failures listed above.
By the way, does the fan turn? If I remember correctly, a dead fan can also cause a boot issue too. -
Re: Ps3 shutting down
A dead fan will probably just trigger the "PS3 overheated, turn off and let it cool down" message and then power off shortly after.
To OP - as momaka said, post the model number. I may be able to help too. (have fixed and modded 6 PS3s so far, including 90nm phats)Main rig:
Gigabyte B75M-D3H
Core i5-3470 3.60GHz
Gigabyte Geforce GTX650 1GB GDDR5
16GB DDR3-1600
Samsung SH-224AB DVD-RW
FSP Bluestorm II 500W (recapped)
120GB ADATA + 2x Seagate Barracuda ES.2 ST31000340NS 1TB
Delux MG760 case

Re: Ps3 shutting down
They usually overheat and burnout. Sometimes it's the secondary-side synchronous rectifiers, other times the primary-side switch transistors. And sometimes, it's neither of these and the SMD ICs and driver transistors on the bottom have huge scorch marks around them.
I have a box of 5 or 6 of these faulty Nichicon PSUs. Came from a batch of 30 or so PS3s with Nichicon PSUs. The PS3s with the Sony PSUs, I've never seen one go bad, or have scorch marks on its PCB. The Nichicon PSUs, on the other hand - even the working ones tend to have those scorch marks. I think Nichicon just didn't do that great of a thermal design on them. Efficiency-wise, I think (or rather hope) that the Sony and Nichi PSUs should be equivalent. But I never had the means to measure them, so I can't say if that's true or not.Comment

Laptop : Lenovo Y520 i5-7300HQ 16GB RAM GTX1050Ti 240GB NVME SSD 1TB HDD.
I bought my laptop in 2018, the guarantee ended in May of this year, it's been working(mainly gaming) fine for all this time except a minor issue with Windows warning me about power surge on USb port all the time when gaming, and it wasn't my mouse, I tried another mouse and the same issue, so I thought it's a driver problem and just ignored it.
My real issue:
My laptop appeared to be shutting down randomly at first, and when I try to restart it, the keyboard lights turn on, the... -
Hey guys!
This is the third laptop here with this exact same issue and the forum threads and YouTube comments are also filled with this problem so I would like to figure out once and for all what's causing it and how to fix it because this model will keep coming to me to repair.
Symptom: The laptop turns on and works fine UNTIL the Windows starts loading, then it shuts down. I can start it again but the same thing happens over and over again so I can't get into Windows. BUT I can enter the BIOS and it stays there forever without shutting down. The same applies if I remove... -
I have a Carvin PA620 powered mixer with a weird problem: channel one shuts down the entire speaker output when plugged in. Its not a short because it still outputs sound through the line outs.
1. voltages are somewhat correct (-42/+42, -26, -17/+17, when it should be +-43, -24, +-18).
2. Channel 2 if plugged works normally, no issues, any volume.
3. Channel 1 if plugged very low volume, works normally. if goes a little louder, it shuts down everything (both speaker channels)
4. line out works normally in any situation, even after shutting down the speakers.

I bought this NAS as "turns on then straight back off again". When I received it it had no trouble staying on, just the RAM stick was in the wrong slot so it wouldn't POST. I was hoping that was all that was wrong with it, but it's now started randomly shutting off once a week. When I find it off it will fire straight back up again if I hit power, no need to power cycle. Nothing ever in the logs aside from "the last shutdown was unsafe".
It's got an internal PSU, an FSP250-50LC (which is wildly overkill for the hardware really). The electrolytic caps in the PSU... -
