Stencil for Surface Pro 5, 6, 7 SSD KBG40ZPZ128G KBG40ZPZ256G KBG40ZPZ512G KBG40ZPZ1T02
Does anyone know where I can find a stencil for this chip please?

Splice DC jack from one Alienware model to another
I waited 5 days for this to arrive only to find it's not the right model! Rather than wait for a China order, I was wondering if anyone knew if it was possible to cut and splice/solder anywhere?
12 pins vs 10 pins, it's a for a Dell AlienWare x15 R2 (P111F003) and the one advertised on eBay was Dell Alienware 15 R1 R2 R3 AW15R1 AW15R2 DC IN Power Jack 0784VK DC30100TN00.
Also, there seem to be 4 wires soldered to the back of the jack on the X15 R2 and only 3 on the 15 R2. What would the 4th one be?

MAG274QRF-QD 27" gaming monitor half backlight shadow
A customer called me up and said that half the screen was like a shadow - presumably the backlight has partially gone. I've never done a repair like this on a monitor, only circuit board based repair on Macbooks etc - is it something that's doable or generally not?

So I fixed this in the end and thank you very much mon2 for staying with me on this. I greatly appreciate it.
It was a shorted cap as shown in the picture below. I replaced it from another board which was also not turning on so I will be troubleshooting that one too at some point. I have a couple of questions:
1) Is there any way to find out what rating etc this capacitor is? I'm assuming the neighbouring ones are going to be the same.
2) This seems to be a GPU or CPU cap. How would it have shown as a full short on the charging circuitry? I thought it would...

This is with the black probe on ground. If I put the red probe on ground the 5M changes to 1.2M1 Photo

Sorry, when I wrote mill I meant million, so everywhere that says mill means mega. Which is the drain and which is the source?

I did replace both of those at the same time before posting this. On the picture I drew on the right side of the mosfet on the right (farthest from the DCIN) is shorted on all pins that side.

54k ohms, however, I found a short on pin 1 ACN so checking the cause of that now.

Opinions on particular soldering iron tip maintenance product
Has anybody tested this product? Posting this question on a Facebook tech group I'm in got a few responses like "that kind of thing corrodes the tips" and "just using normal solder paste is much better" so I'm not looking for generic responses like that, but rather, does anybody know for certain whether this exact product is good or bad for soldering iron tips?

Thanks, found the BQ24780S chip. I had actually looked for it before but missed it because it had a sheen of tape residue on it so I thought it was an unusual laptop with a different type of charging circuitry that I hadn't come across before, hence me posting the whole board back and front.Last edited by kalemaroni; 04-12-2024, 03:47 AM.

Asus UX582L no power
I have 20v coming in but it stops after the first mosfet and I can't find any voltage anywhere on the board. I replaced both the mosfets and it made no difference. Anyone have any pointers as to where to go next? Many thanks in advance...
