NMG2 unresponsive switch buttons

Hi,

On my G2, 50% of the switches (like octave or variation selection) are very little responsive. I need to push them HARD to register the press.
Is it a common issue ? Any advice to give them their youth back ?

In my experience, every Nord synth I have had (and these are many) needed the love of some contact cleaner in the buttons eventually. Fortunately all the Nord synths are really easy to disassemble.

Thanks, I'll take care of my beloved G2, then !

Before using contact-cleaner, try pressed air to clean them. At least i did and all my buttons work again.

Help!
So I dismantled the control panel of my G2, but I'm not sure how to remove the switch caps without damage. Any tips ?

They do come off pretty easy. Just a squeeze and they will pop out.

One bit of advice: while you are in there, clean all of them, even though it is a daunting task. I opened mine to do the Store button, but missed another button that I forgot about. So I have to open it again, later.

Thanks @jamos.
I took the time to clean them all (isopropyl alcohol, then a touch of contact cleaner). Had to reopen 2 times though, to fix some switches that were still unresponsive, and also one switch that was mechanically stuck due to screwing the PCB too tight.
Also I couldn't unscrew the pitch stick as one of the screws was damaged, so the operation was a bit tricky.
All in all it's not that trivial, but it's now working perfectly !
