I forgot to update the post, but it was indeed one of the fuses on the mainboard that was blown. Thank you for your help! -
iPhone 13 mini not booting, shorted test pads
Hello everyone,
I am trying to diagnose an iPhone 13 Mini that does not boot. (Amp meter shows a couple milli amps then goes to zero, looping).
Here are some measurements I took :
Is it worth trying to repair this?
Thank you... -
Thanks for the reply. Hopefully removing the tray is not too difficult.

Sony DVD player stuck tray (DVP-SR310P)
Hello,
I have a Sony DVD player with a stuck tray. It seems that moving or pressing on the tray makes it work.
Anyone knows why?
Thank you.... -

A1398 15” 2013 short when screen plugged in
Hello,
I have a MacBook Pro 15” A1398 2013 that has no backlight, but I see an image when putting light through the logo. I noticed that when the screen is plugged in, I get a 300 ohms short (see image).
When unplugged, the short is gone.
Any idea? -
Thank you for confirming. Could it be that the MAIN motherboard should be supplying another voltage, other than the 12v? I checked everywhere else on the disk drive board and all I can find is the same 12v at its source...Leave a comment:

Sorry for the double post, but I’d like to add that the shorted component that I removed was there (see photo). Could it be the reason it is not working? I thought it was only a capacitor and that it could work without replacing it. Can anyone confirm the component that was in this location?Leave a comment:

The tension at the point you mention is 12.09vLeave a comment:

It does look like A8=XXX, hard to tell
I am only getting the 12V
Here are the diode readings.Leave a comment:

Thank you. Based on the data sheet you provided, it implies that there's 12v on the EN pin only. This seems strange. Also, the ground doesn't seem to be at the same place on the board vs the data sheet. I'll have to investigate further
edit: ground is at the right placeLast edited by bogosort; 01-22-2024, 12:11 PM.Leave a comment:

Is it possible that the component (the one with 5 pins) is bad? If so, anyone can identify it? It says A8-P1P on top of it....Leave a comment:

PS5 disk drive not working
Hello,
I am trying to diagnose a PS5’s disk drive that is not working. At first, I found a shorted capacitor. However, after removing it, I cannot find any other short but it still is non working. I measured the voltage at this place (see photo) but there’s only 12.11v at one pin. Other pins all show varying voltage between 0 and 50mV. (Constantly changing)
Any idea? -
I managed to find out that it is probably a step- down DC/DC regulator by comparing the ground pins and voltage pins. Would it be worth it to try and fix this motherboard since this looks very close to the gpu?

There are 16 pins. We can see what you’re asking on the first photo (the darker one with the chip removed, we can see 16 pads and 3 burnt one)Leave a comment:

Lenovo Slim 7 Pro X - Burned mosfet identification
Hello,
I have a Slim 7 Pro with a burned mosfet. I tried searching online but cannot find anything. (I ended up on the Non-X schematics)
Please see attached photos.
It looks like it is written S2EGD on it.
Thank you!... -
Thank you! Is there a way to find this kind of information or is this your knowledge?Leave a comment:

What is this component marked G75LL on it? (U15) from a KW-M56BT audio system
Hello,
This audio system does not turn on and I managed to see that this component heats up when powered.
Anyone knows what this component is?
Thanks...
