If your Logitech G27 will not respond properly, even after calibrating, you may need to replace its optical encoder. The optical encoder is a small electronic device that turns the wheel's rotation into an electronic signal for the computer to understand. It isn't too hard to replace, you just need plenty of patience because you'll be taking out a lot of screws! Make sure your wheel is completely unplugged before starting this replacement.

Hello and thanks for the guide. I understand this might be off topic, but would you happen to know the pinout of the7-pin connector in step 5? There is no label on the pins. Thanks in advance for your time.
Are you sure about Step 19 alignment. Some other guy with G25 says it has to be dead centre alligned otherwise you get blinking lights.And that's exactly what happens to me.
hi! i reassembled mine positioning it all the way to the right, and i have blinking power light and my wheel do not calibrate. what do you mean by dead centre aligned? i have to assemble it back together in center position, is that it?
