I got this free TP-Link Archer C9 v2 router.
It has 8 LED status lights. There seems to be 2 banks of them, and the right 4 of the 8 are working properly. None of the other ones work, but you can barely see a dim light coming from them. My theory is something has failed closed and thus is sucking the power out of the left bank. Another theory is there is something wrong with what is supplying the power to those LEDs. The router otherwise works properly. So I am wondering is there is any overheating/power loss possible in this case, or are these designs someone done to eliminate those problems?
Here is the V3 pcb. I can not find a photo for the V2 one.
