Wii Remote Plus Accelerometer issue

[Blythe93]

Today I've noticed that one of my Wii Remotes has an issue with the slow vertical motion. IR sensor and pointer works totally fine, swinging it left and right works as well. Swinging it up and down, however, is really slow.

For example, I've been play Mario and Sonic Winter Olympic games and in curling event I can't set the strength of the swing at all. Other Wii Remotes work just fine, no issue at all. This one's just way too slow.

Is there any fix I can try? I've tried removing batteries and resyncing it to the console, leaving it on a flat surface, even slightly hitting it against my palm. Nothing fixed the issue. I'm guessing it's probably hardware related but I'm not sure where to look at, I wonder if its sensitivity can be tweaked or something? I haven't tried plugging in the Motion Adapter to see if that would fix it or just confuse it even more.

Any help is very appreciated! Thanks in advance!

At a glance I couldn't find any diagnostic homebrew you could run on a Wii, but have you tried connecting it to your PC and inspected sensor readouts in Dolphin? Just thinking it could narrow down the issue to a specific sensor (which can only be gyroscope or accelerometer in this case).

Will try that when I get home, thanks for the suggestion!

Sadly, I've swapped the batteries and tried a different game (Wii Sports Club, bowling) and yeah, issue persists. Will definitely check via Dolphin to see what's really happening and, if nothing else, I'll buy a replacement Wii Remote Plus and swap the internal PCB. Thankfully, I have a lot of spare ones, but it's sad to see a mint controller go bad.

Sadly I think that would end up being the case, given that you'd have to desolder and replace SMD components to fix just that faulty sensor.
