wifi模块故障导致Switch卡logo和橙屏故障的维修

The previous video repaired a switch motherboard of a friend from Hong Kong that caused the logo of the card because the coupling capacitor on the side of the cpu fell off. Friends who have not seen it can take a look at the link below.    • Switch拆机，开cpu屏蔽罩导致电容脱落，开机卡logo的维修(来自香港的Swi...   Today I repaired another Switch motherboard sent by this friend. The fault is manifested as unstable WiFi at the beginning, sometimes an orange screen. Later, the card logo did not turn on. After maintenance by the owner, the fault stuck in the second logo and became stuck in the first logo. After replacing the CPU power supply chip, the problem of the first logo of the card was fixed. However, the orange screen and card logo still occur after replacing the new wifi chip. Until the original wifi chip of the switch is installed back, the fault is resolved. So I guess whether the switch is also bound to the wifi chip. If the wifi chip needs to be replaced, it will not work without modifying the underlying data. Please answer me if you are in the know, thank you!
