Re: the gutless, bloated, and fried power supply hall of shame
CapXon and Ltec would fail anyway... note the unbulged Taicon, those actually seem like OK caps, haven't seen any fail YET. It's less ambient temperature and more ripple current that kills crap caps.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: the gutless, bloated, and fried power supply hall of shame
I removed the caps today, and I got a photo with some better light. Now you can really see how bad the heat discolouration is
EDIT: I also took the failed fan apart, and I think there was more to this than just bad sleeve bearings. It looks like there was lots of rust around the magnet on the blade housing and on the motorAttached FilesLast edited by c_hegge; 09-07-2012, 12:45 AM.I love putting bad caps and flat batteries in fire and watching them explode!!

Re: the gutless, bloated, and fried power supply hall of shame
Not nice, really. In some worse fans when sometimes the magnet tends to rub against motor I lubricate it with vaseline. Maybe if you will clean it you can as well use itfor conserving again corosion.Less jewellery, more gold into electrotech industry!

Re: the gutless, bloated, and fried power supply hall of shame
I probably won't worry. I have a few spare Yate Loon fans which are in much better condition, so I'll probably just replace it with one of them
EDIT: I probably should also add that the plastic washer which holds the blade housing to the motor crumbled when I took the fan apart.Last edited by c_hegge; 09-07-2012, 04:37 AM.I love putting bad caps and flat batteries in fire and watching them explode!!

Re: the gutless, bloated, and fried power supply hall of shame
I wonder if the rust is what jammed it?

Re: the gutless, bloated, and fried power supply hall of shame
If that power supply lacks protection circuitry of any sort, that may be why it still works with bloated capacitors.Comment

fried Apple power supply
There's me happily using my old Apple PowerBook 1400, then the next time I come to use it, nothing. So I open up the little brown brick (the official power supply) and was amazed to discover the destruction shown in the pik. I have no idea what caused it.Attached FilesComment

Re: the gutless, bloated, and fried power supply hall of shame
Wow! That really is the most toasty, well-done PSU PCB I've seen. I'm surprised the output choke didn't burn.
Not good.
Although likely salvageable if you cared enough to fix it. I would - extra spare junk fans for the random project never hurt. Sandpaper and a bit of oil is really all you need. When I find a fan that has started to get rust on the stator, I just lube it with machine oil.Last edited by momaka; 09-09-2012, 05:05 PM.Comment

Re: the gutless, bloated, and fried power supply hall of shame
As I stated, I use vaseline, it is better I think. Oil just vaporizes or dries out due to absorption in dust. Vaseline is more durable I think and lubricates even full of dust.Less jewellery, more gold into electrotech industry! Half of the computer problems is caused by bad contacts

Back in 2020 i bought a (2nd hand) compact ATX psu to replace my current one. My PC case only fits very short ATX power supplies so i didn't really have the choice of buying a decent 80Plus unit. The current unit is a modded YoungYear unit that i made a thread about a while ago:
A "nice" YoungYear unit? - Badcaps
The "new" unit is a KDM-M6480 480W psu, the 480W number is a typical KDM bullshit claim of course, but the 24A rating on the 12V rail seemed reasonable and the "Active PFC" claim gave me a bit of hope that this was going to be decent-ish.... -
Introducing... the POS-124Z which really is a POS:
Yep it's a POS allright.
I tried powering it up. It's a KILLER - not fried, but sure will fry things! I got 21V out of it unloaded according to my DMM!
I tried 21W load (car lamp) - got 16V, which is really pushing that lamp.
Then I tried a 50W load (car headlight) - got 13.2V. Not too bad but this is with the heavy load...except the circuit breaker kept tripping.
So I had to take a peek:
EIEW. Looks like a Darlington emitter follower + Zener device. Heatsinking?... -
Hi,
I'm learning electronics(already have some basics) by fixing a FH52M LA-J891P rev1B. It come from an acer nitro 5. The charger was defaulting upon pluging. The 19V rail resistance is 0ohm (I believe that caps screw my measurement). When i inject 5A, I get a rail tension of 1.3V, and 0.8V vcccore.
Except the cpu, I cant feel anything getting warmer.
I believe that it is normal, because the cpu is "eating" half the power I'm imputing.
I dont know if the cpu is fried, because I did not remove the big capacitor on vcccore.
I believe that if the cpu was fried,... -
While our PSU hall of shame thread is fun I thought It'd be fun to have a ripple hall of shame thread too
I'll go first out, it's an industrial PSU that offers +15v -15v -5v +5v rails.
However it has been mounted on a frame with DC/DC converters for producing +12v and -12v as well.
The caps for this have gone a bit high ESR
The measured ripple is around 1700mV, or 1.7v!
After recapping the ripple is gone, also note that the scale on the scope is 50mV/div instead of 500mV per div in this shot
-And that's how you know you have a qualifying... -
Hello!
Looks like I fried something when my EDP cable got squeezed on the hinge. I replaced the cable but still no display. Laptop works fine with external monitor connected through HDMI and Display Port-USB C port. I took it apart and I see a burnt component. Can anyone help me identify what this component is? I tried to use schematics for another G15 but it does not match on the amount of pins and size. I attached pictures. The component has a label on it - (21A29)
