It does. The only components that are common to all three indicator lights are the power connector and the reverse polarity FET.
You should be able to smell the problem if the FET is the root cause. This part can be replaced by someone with moderate soldering experience and a nice hot iron.
I'd be surprised if it is the power connector - you would be able to see damage there.
There could be a short across the VBATT rail, but you would hear the PD breakers clicking.
