So not long ago i bought this Logitech G25 from a person. It worked really great. Then suddenly steering wheel stopped working and power light just flashing. I didnt thinked of it alot and put it aside. Then I took it to play and it worked again. Then few weeks or so later it happend againt wheel deosnt calibrate and almost same thing exept power light dont flash but is very very visible. I guess i can say DIM. Please help i want it and now it deosnt fix like last time itself. I have power supply "power cord" its fine on and i tried do unplugg everything power cord usb etc. Then put it again, use different channels for power cord and usb other usb ports. Nothing worked still same and i dont have other power cord i have one but ending deosnt seem to fit on the wheel with loptop's power cord. Thanks.

I had similar problem, lights on shifter were blinking and wheel couldn't calibrate itself.
Wheel worked again after changing power adapter (found similar one in my workplace)
