Damaged motherboard on a scratched Nintendo Switch.
Damaged motherboard on a scratched Nintendo Switch.
Beyond the Left and Right JoyCons differing in their control buttons, the main distinction in the Right JoyCon lies in the inclusion of an IR camera module and NFC reader/writer. The sole additional component visible in the upper right corner beneath the display is the battery compartment. (Further investigation reveals details about the charging IC chip.) These devices are quite compact, but they offer a lot of insight. I gained a great deal from this experience. Some quick findings: These units tend to overheat, though it doesn’t appear to affect the screen directly. Examining thermal pads or tape suggests they’re not used on the CPU cooler’s top surface—just thermal paste. Concern remains about the heat sink area, possibly using a small plate with paste only. I’m inclined to assume the thermal pad/tape is unnecessary based on online sources. Lastly, I suspect the charging IC chip is positioned on the back side of the PCB near the battery area. It would be worth checking if overheating is also a concern there. These parts are generally replaceable, and it seems to be a common problem. Since I can’t take apart one here without personal access, my help is limited in this regard.
