Hello all,
I'm working on an Acer Nitro 5 (AN515-54) with motherboard EH5VF LA-501P with a short on the power rail.
I'm just learning board level diagnostic, but here is what I've found so far.
I injected 1.5v to one of the positive leads on the DC jack connector (PJP101) and read about 1.4a to ground.
I felt around for heat and found the MOSFET at PQB12 is rippin hot!
when i pulled the MOSFET from the board the short went away. In my mind it was a faulty MOSFET.
Ordered a replacement and got it installed only to find it gets very hot again and the short returns....Yesterday, 06:07 PM -
Good afternoon,
I'd appreciate help diagnosing my A2442 that's only taking 5v and 0a
This was my personal laptop and I had closed it at the end of a class and opened it in the next class when it just didn't wake up from sleep (The battery was charged). I connected a charger later that night and it booted right up but touch ID stopped working. The next day it did the same thing but never turned back on when I plugged in a charger.
I though the touch ID issue was weird but I'm not sure if that info helps.

Hi everyone!
Hope you're all having a great day, and thank you very much for stopping by and taking the time to read this post to help me with my parents' Samsung TV.
My issue: No backlight.
Model: QE82Q70RAT
Type No: QE82Q70RAT
The TV was already serviced by Samsung once under warranty for the exact same issue, but six months after the fix, the backlight went out again. Now, Samsung is asking for nearly the same price as a brand new TV to fix this with the same 6-month guarantee.
So hopefully, I can fix this cheaper.

Hi Folks
I've got a friend's LG OLED on the bench (well the dining table given the size of it!). It immediately powers off when turned on and sits in standby. PSU voltages are good and after disconnecting the TCON board there is stable 12V and 22V coming out of the PSU board.
Hunting around the TCON board there appears to be a shorted power rail (DVDD09_CORE) but I'm having issues identifying the component which is shorted. I've attached a picture. It's sitting before the coil so I'm assuming it's a MOSFET of some description, but the markings I can make out don't seem...Today, 06:27 AM -
[U]Hardware Details - Samsung LC24FG70FQWXXL (C24FG70) Monitor with the board model (BN91-18169A) perhaps aka (BN41-02548A)[/U]
While wall mounting, I mistakenly picked a screw 0.5cm too big than the clearance and damaged the trace and one of the part (a capacitor, I think) on the board. Images attached.
Is this repairable or will I just have to get the entire board replaced? Please guide about this.[U]Hardware Details - Samsung LC24FG70FQWXXL (C24FG70) Monitor with the board model (BN91-18169A) perhaps aka (BN41-02548A)[/U]

I am trying to downgrade my bios on my Alienware so I can undervolt & overclock my CPU, and overclock my ram. I need to get to bios 1.2.2 for this. Dell doesn't allow downgrades, and their bios file is an exe compiled in c++, so I can't decompile it easily. I am wondering if I can flash the bios manually using a usb flasher. I would like to know if this is possible, and if so, where the bios chip would be. I know flashers are pretty cheap and the bios chip is 8-pin. There are two of these chips only when I open the back panel of the laptop. I'm not sure if there are any on the other side of...05-17-2024, 03:34 PM

Hi,
I'm troubleshooting SN board of Panasonic plasma TV and I'm curious about a component that looks like an optocoupler, it has 5 legs though. I tried to check between legs 1-2, but no diode junction there, it's open. So either that is not a diode there or it's burnt.
For future searches, the part num is B3PBE0000060, the label on the component says 9157 and N219.
Any idea?

Hey, I'm repairing a board from liquid damaged laptop, managed to get 5V and 3.3V rails up, some passives were corroded away. Only problem right now is no reaction to power button, there is no PCH_PWR_EN signal, DPWROK_EC is 2.5V, +1.0VALW is missing. Replaced KBC with brand new one, reprogrammed. No change. Any ideas? Schematic and boardview are available, attached them at the bottom. Boardview file can be opened by "BoardViewer" software.
