M-Touch Parameter sliders not working

My M Touch seems to suffer from an issue where the 4 right hand sliders used for paramter setting don’t respond to touch. Curiously the bank of rubber buttons don’t work either, nor the Highlight button, but everything else is fine. I vaguely recall seeing a fix for something like this in a software update, but I’m running 1271 with the M-Touch and it’s still doing it. I had this about a year ago, but it suddenly started workin again. Is this likely to be a hardware issue, or a software issue?

Hello,

Sounds like an hardware issue, my M-Touch died after 6/7 years (starting with belt encoders malfunction, and ending up to main playback fader always on (value not changing, but blocking NX1/NXP controls).
