Hello everyone. Currently picked up a free Radion xr15 pro gen 3 it was not taken care of well. Took it apart cleaned all encrusted dust from fans and cooling fins. Inside the electronics was clean. Removed sticky residue from outside edges. I put it together and tried to start it up and I only get a single red flash from the 3 buttons. I tried using another power supply and same results. Any feedback or guidance is greatly appreciated.
