Yamaha MT8XII Transport won't work- button presses do not register

[RuminantBoy]

Hi all,

My Yamaha MT8XII Transport section won't work- button presses do not register.

Last year, button presses worked intermittently, but playback would eventually slow down.

Is this a case of bad belt AND bad motor? Or just bad belt?

All inputs and outputs of audio, besides recording and playback, work normally and produce sound.

Thanks!
