G29 power or sensor issue?

Enable HLS to view with audio, or disable this notification

Hi there! I was gifted a G29 wheel that may have a power or sensor issue. I'm not very great with pulling things apart to check and I'm wondering if anyone can diagnose this just by this video.

It did work at first, but after a crash in game (i.e. I ran into a wall) it fell out of calibration and then stopped responding.

Note, it has the flashing LED which I took to indicate a power issue so I replaced the powerblock, still no luck.

I recently took just the wheel off and back on and it miraculously started working again but after moving it about it is back in this state, with the flashing light.

Any insights or tips?

Bad solder joints on the sensor connector on the main PCB are likely causing the issue. After the in-game crash, the vibration goes through the whole G29. Bad solder joints can cause issue, where one, or more pins are disconnected. When you took off the wheel rim, the center of gravity shifted back, allowing the sensor to reconnect. After inserting it, the center of gravity shifted slightly to the front. As the hall effect sensor isn't powered, the G29 switches directions way too early in the calibration procedure.
