I've considered opening a mail-in repair business run out of my place but that is one of the fears that is holding me back...roaches. I once lived in an apartment complex that acquired roaches and they never went away. I fear getting a package with live ones and winding up growing an infestation.
Roaches are a reality in the console repair business. Some claim if you put the console in a plastic bag along with a rag soaked with isopropyl alcohol and seal it up tightly, it will kill all the roaches inside overnight. Have not tried it.
In a few videos when you blow out the console with compressed air, I cant tell if the fan was still connected to the motherboard. I know that these things will generate a voltage when spun by the compressed air. Not sure how well the fan circuit could tolerate it. Perhaps you can explain if this would be an issue or not? Thanks.
A conventional DC motor will act as a generator if spun but this fan is not conventional. It is a pulse type motor with drive circuitry built into the fan. I don’t believe there is any chance to generate a current.
Does it work in safe mode while connected to the USB port? If It works in safe mode while connected but not normal mode, your Bluetooth/WIFI module is probably dying or dead.
