ASUS X571 no power : battery issue?

[mkdj]

Hello everyone,

Mark and model: ASUS X571
Symptoms: not turning on. There is only the LED battery indicator working. The owner of the laptop told me this problem arrived one week after having changed the battery. He then managed to power on the laptop only once, and then it never powered on again.

Tests already made:
- Battery is charging when laptop is plugged in. The LED battery indicator turns white after a couple of hours of charge, indicating that battery is fully charged. However, laptop won't turn on anyway, with or without AC plug.
- I have removed...

Hello everyone.
I'm here to ask for help troubleshooting an issue with my Acer Nitro 5 An55-515. Board number fh51m LAJ871P .
The laptop turns on without any image, and after inspection, I noticed the 1.2V voltage was reading 8V spikes. The PQM1 MOSFET's gate was shorted to the source.
I replaced PQM1, PQM2, and PUM1. After turning on the machine, the 1.2V voltage appears correctly for about 1 minute, but after that, PQM1 shorted again. The MOSFET and controller assembly has already been replaced twice and continues to blow. I can't understand what's going on. I should also add...

Hi,
it's a PoE camera and it stopped working. Using thermal image I identified failing component U22 marked as 16AF which seems to be buck convertor TI https://www.alldatasheet.net/datashe...62569DBVR.html. I took it out and It is inteed shorted on the output. However, after I took it out, the resistance between the output pads (on the board) still shows 190ohm, is that bit low?
Another issue is, seems to me I must be missing one of the tiny resistors R810 that should make up the voltage devider for the buck convertor. Honestly I did this months ago, I cannot...

Dear forum

My Samsung fridge died from a fault on the mainline and the transformer (https://www.hqelektronika.hu/hu/halo...-w8-da2600009k) died.
No voltage on the secondary, measuring resistance shows open circuit. I concluded a blown fuse which is deep inside the transformer, I don't think I can disassemble it to replace the fuse.

The second problem is that I cannot find an original replacement part anywhere or even If I do it's pretty expensive.

My question is: Can I replace this transformer with a generic 230V to 17V one? The output has 4...
