Control 24, one fighting fader.. shall I replace it?

[Trey Songz]

Hello,
So I have bought a used but in great condition Control 24, I plan to use along with V-Control Pro.

One issue is that, i have channel 12 fader not responding to my touch.
So, TEST mode, there is no T at all.

At first, channel 6 fader was similar but I made it work by just cleaning with tissues.

Channel 12 fader, very firm and just does not recognize at all.


Cap off, no 'T' sign at all.

Other faders are all good and T test all passed.

um, could this be 'circuit' issue?

Shall I replace this one fader.. would there be any other troubleshooting check-up methods..?

I did 'reset' twice. Cycled for 10 minutes.. channel 12 fader still acting all ok 'except' it cannot recognize touch <--- I cannot bypass touch fader mode right?


What would be my best bet..?


Thanks.
