Damaged motherboard on a scratched Nintendo Switch.
Damaged motherboard on a scratched Nintendo Switch.
Since I've experienced fewer issues before and the scratch appears to remain separate from the rest of the PCB, it seems to be well contained.
Screen overheating? That means the display is getting too warm.
Is the power source positioned where I expect it on the board? It might be overheating during charging or use, which could explain the issue. I’d need more photos to understand better. I haven’t seen any internal components before either. Also, did you accidentally insert the screwdriver more than once?
it only gets hot when the lcd display is active, even during charging, while docked mode keeps it cool. No other issues have appeared after inspection. I suspect the LCD is receiving too much current, possibly due to damaged conductors affecting its regulation. Turning it on didn’t trigger overheating, suggesting the problem lies with the screen itself. The battery drain is also noticeable.
This large tracing appears to be a standard reference point. When magnified, the image becomes unclear. Touching another area above it might affect the result, but without a clear view I can't confirm. I don't believe a minor scratch is significant unless stated otherwise. Also, it seems unlikely that a single screen corner would heat up from power alone; the whole screen would probably warm up. Right now I'm reviewing a hardware breakdown to better understand orientation. Let me know if you have any further input. I'll share my thoughts shortly.
It could be a part of the LCD that’s getting too much current and overheating, but the motherboard seems to be the main issue. The same problem shows up with different LCD screens, except this one does not. I’ve checked a different motherboard and it works fine. Here’s a broader view of the situation. Don’t worry about anything disconnected—I reconnected everything during testing, so no need to question that.
This appears to be a ground plane. Scratching it has no effect. You haven't unplugged anything and didn't touch any of the smaller traces. To avoid short circuits when assembling everything, consider using a bit of nail polish. My guess is the issue lies with either the screen or a damaged part.
