I recently bought a used DSi XL off Ebay, the system powers on and can play games fine, but someone removed the camera cable from it, causing a system crash when using the camera. I got a replacement cable and did the repairs myself, but after reconnecting everything, I power it on, and get a bottom screen flash before it turns off. After researching the problem, I realized the top screen's cable wasn't in all the way (I assume was the issue, because I did struggle to insert the cable through the hinge and was worried I damaged it). After inserting it properly, I go to power it on, but now the system doesn't power on at all ( I get a flashing orange light). I had noticed afterward that I might have crushed the power board's black-and-red wires, which I'm assuming is the problem, because everything else seems to be connected properly.

Edit: I tried to pop out the top screen's cable to see if that was a potential problem, and no, it still doesn't turn on.

Second Edit: Alright, I did my best to get pictures of what I believe the problem to be, but taking photos of these tiny cables is difficult to get clean images of. I hope these can help pinpoint the issue with the DSi.

Third edit: We discovered through testing that the F1 fuse on the power board was blown, and that applying tinfoil gives us power. However, the top screen still shows up blank. This time, however, the top screen can show jumbled pixels or wonky screen imagery, or rapidly flashing when applying pressure in specific spots (seemingly, on the ribbon cable attached to the screen). Can the system be salvaged in this case? There doesn't seem to be any noticeable damage on this specific part of the cable, but perhaps I damaged the strip that coils inside the hinge when fitting it through?

Hello! I found a dirty, roach infested, rust infested, ps4 model CUH-1215A underneath a trash heap. It boots up, works fine, and I started to clean it up. The only problem is these dark spots or burn spots on the ground of the motherboard.

I did research and talked to A.I. saying this could be a burn spot and I need to chip away at the surface and put epoxy? to make the surface even with the rest of the MoBo?

Scraping the MoBo seems unsafe, unsure what I should do here. Any suggestions? preferably from somebody very experienced.

I attached images to show what the spots look like.

The original cable has this printed on it:

SUMITOMO-G [RU] AWM 2896 80C VW-1 -F-

I cannot find a ribbon cable that is the exact same. Can I instead buy ++this one for example++.

There's definitely some corrosion on the board in the bottom left. I didn't want to scrub too much away yet though, since it looks like maybe the surface of the board is cracked? Is that cleanable?

One of the pins in the cartridge slot, all the way on the right when the back cover of the GBP is off, is higher than the others. Is this normal?

Any thoughts or insights are much appreciated!

Has anyone tried this method? If so, are there any specific pitfalls I should watch out for? Also, are there existing guides I can use as prerequisites for removing the motherboard or midframe to make the process smoother for users? I want to make sure the guide is as efficient as possible while still being safe.

I recently successfully replaced the M92T36 IC on a Nintendo Switch motherboard using a hot air station. The console now boots up and charges normally. However, I am now facing an issue with the Right Joy-Con.

When I slide the right Joy-Con into the rail, the console does not detect it as attached (it stays on wireless mode). I opened up the console again to inspect the area and noticed that the ribbon cable and the FPC connector look perfectly fine.

However, upon closer inspection of the small SMD component cluster right next to the FPC connectors, I noticed that one SMD component at the very bottom of the row is completely missing (likely blown away or knocked off accidentally during my hot air rework of the M92T36).

I have attached a micro photo of my board showing the missing component's empty pads, alongside some reference screenshots from the iFixit teardown guide for comparison.

My questions are:

1. Is this missing component a resistor (in-series) or a filter/bypass capacitor (to GND)?

2. What is the exact value/specification of this missing component (looks like a 0402 package)?

3. If it is a resistor on a data/detection line, can I safely bridge the pads with solder or a jumper wire to restore the detection functionality?

I have a multimeter, soldering iron, and hot air station ready to fix this. Any guidance or schematic insights would be greatly appreciated!

Thanks in advance for your help!
