AX3000G Keylock/Tuner Problem

[Nightmist]

Hey guys. I have an AX3000G that I haven't been using for a while, a month at most. Today, I wanted to play some and plugged in, however I can't activate the keylock. I hold the "Exit/Tuner" button while the name display shows the current program but it just switches to the tuner. No matter what I do, I cannot keylock. Also, holding a pedal doesn't switch to tuner or mute. Any ideas?

I just repaired one AX3000 and among other things I replaced 6 microbuttons on its main board.
Someone had repairerd thos unit before me and had replaced 5 more buttons.
The ones I replaced did not work at all or worked very poorly.
Idea is here that these buttons go bad, especially ones that are under footswitches but not only.
Most probable reason is that Exit/tuner mirobutton below the visible one is bad, it does not conduct currents as it should.
In short perspective little harder pressing may help but if you want to use your board longer then replacing buttons is the way.

Hello, I have the same problem. But I don't think it is a wrong microbutton. It has to be some system problem, when holding a pedal doesn't switch to tuner or mute too. Tuning is very uncomfortable now and there is a big danger to touch some knob and change sound during live concert

The problem still persists. I don't know if it is due to the buttons or some other issue. I'm living in Turkey and not even in Istanbul. And there probably isn't any person around the place I live who is qualified enough to change those buttons or even find out what's the cause of the problem. Any possible solution or suggestion would be very welcome. Thanks for the answers, everyone.

Sounds like the tact switches have worn out, you need to replace them with some new ones.
