by MisterAILHi everyone,
Brought a non functionnal PS5. Apparently only a bad PSU...
No beep, nothing.
After some tests i found this :
- PSU is fine (12 volts stable)
- 12 volts line is shorted
- DA9065 was fried, F7003 also => Replaced both of them, short is gone on 12 volts line, no dead short anywhere else.
- By the way, nothing change. No signal, no power, no beep.
Mesuring all rails with my workbench psu (12 volts input)
- 0.00 amp drawing
- 12 volts, 5 volts, 2 volts, 1,15 volts are presents (suppose new DA9065 do is...5 Photos -

(Had 3 problems, now just 1)
I have no experience or knowledge and usage of tools to repair devices besides the entire past 12-10 days of researching, watching YouTube repair videos and troubleshooting this laptop motherboard. ChatGPT was used as a guide to ask questions.
I used boardviews of mostly FX505GD-M, and some FX505DU, FX505DD. Used schematics of FX505DU.
I had originally intended to replace the BQ24780s first (due to previous battery removal while benchmarking) but I... -
by mr.DataI have a dead Asus ROG gaming laptop with liquid damage. When I measure the first mosfet, there is 19V. On the second mosfet there is nothing on the input and 4.3V on the output but it is not continuously. It is going up and down.
I have read this article:

Is it through that inductors can never be shorted?
I have 2 inductors near the GPU that are shorted. Does this mean that the GPU itself is shorted? How can I know for sure? -
by joshAUHi all.
This notebook was showing no signs of life.
I removed the FH52M LA-J891P mainboard and found that there was 19V at the DC jack.
However there was zero volts on the two PRB2 and PRB46 resistors immediately after the two polarity protection MOSFETs (PQB11 & PQB12).
If I remove the PQW1 MOSFET, the 19V rail starts working, and I can turn on the unit - at least I get the fans, and the power light comes on, when I simulate the power button being pressed. No display.
I tried replacing the MOSFET with a new one, but again no voltage on the... -
by YanlebHi every one. I just want to share the successful repair of my shorted Panasonic TNPA4782AB SC board.
I don't usually do it but so many parts were shorted that I decided to buy the ShopJimmy repair kit instead of sourcing each components individually. Here is the list of components the kit contained, with a remark indicating if I needed that part or not :
D608, good
D618 RF101L4S, good (See warning 1 below)
D619 RF101L4S, good (See warning 1 below)
D865 RF101L4S, shorted (See warning 1 below)
