Re: HP Laptop not detecting internal screen (HP 15-cs0906nz)
Thank you, really proud of myself for managing it, especially after a repair shop held the laptop for 2-3 weeks and didnt even try to diagnose by the look of things.

Re: HP Laptop not detecting internal screen (HP 15-cs0906nz)
Update: i fixed the problem.
So if anyone from the future sees this, it was the 5 pin L2A4 mosfet. It shouldnt be shorted to ground on any pins other than the middle one of the 3. I didnt have an exact one, but used one from a 2010 macbook air motherboard. The thing that gave me confidence was the fact that it was right next to the lcd connector- so it served the same purpose as mine. And im really bad at understanding datasheets for the various chips.Leave a comment:

HP Laptop not detecting internal screen (HP 15-cs0906nz)
So this is a continuation of this tread: [url]https://www.badcaps.net/forum/showthread.php?t=106465[/url], since it went cold i cant expect any help there.
TLDR: The laptop model from the title works on external display, doesnt display to an internal one, i found new clues.
The white thing i thought was the backlight fuse isnt that 100%, tested on another similar laptop which has a working screen and it measures the same behaviour. Its to do with one of the ports.
Other thing i...Last edited by honestmstk; 06-23-2022, 06:41 PM.Leave a comment:

Its kind of blocked by the ram slot so i dont see which track it is, but i measured all of them
4 or 5 are measuring 1ohm
2 are measuring 46 ohms (not next to each other)
rest are open line...Leave a comment:

Re: HP Laptop not detecting internal screen (HP 15-cs0906nz)
I tried going from the right pad of the fuse (the side which is disconnected from everything and not a ground) to the pins of the lcd connector, and not a single beep. I thought the voltage pins would be connected to that, guess not....Leave a comment:

Around two ohms on the fuse. Can you tell me which pin is the 19 volt on the connector? Ill try my best to find it in the meantime. Thank youLeave a comment:

HP Laptop not detecting internal screen (HP 15-cs0906nz)
Hello everyone, as mentioned in the title im having problems with the screen circuitry. When i got the laptop it had a burnt hole in its screen cable and a few broken wires. It displayed on an external monitor without issue, still does. I ordered a replacement cable and popped it in today but still nothing.
I then looked around on the board to see if theres a fuse that couldve blown and found one. Not entirely sure if its a fuse, i mean its white ( ill be attacing pictures), but it doesnt have continuity. I looked to see where the connection went and from the left side of the fuse...Last edited by honestmstk; 05-16-2022, 01:35 PM. -

Need close-up image of ASUS X442U Motherboard
Hi guys, i bought a broken asus x442u laptop to try and fix. The power light would blink once and the chipset (die next to the i7 processor) would get hot momentarily, if i kept disconnecting and reconnecting the charger it would get reeeally hot.
Anyways, i narrowed it down to two mosfets that had shorts. Because i didnt have the same ones to replace, i used some similar looking ones. After those were installed, it didnt give any signs. I then realised it had the exact same two mosfets feeding the GPU. I probablyy should have tried those first, but again no signs of life. ... -
