Korg M3: Touch Screen and Battery Replacement Guide
Cautions:
1. Never open your M3 module with the mains still plugged in –there are live contacts inside.
2. Opening your M3 module will invalidate any remaining Korg warranty (although the warranty may not be much value if
Korg cannot supply the replacement part).
3.. I can’t accept any liability if you damage your M3. If you think that the steps below are beyond your technical skill, get the
module repaired by a professional. Taking the utmost care as you work, and a small amount of technical skill will help avoid
damage.
4. Tools and materials required:
- 1pt and 2pt Philips (not Pozidrive) screwdrivers.
- Sharp bladed knife (e.g. Stanley knife).
-Double-sided sticky tape.
-Something to protect the knobs on the module when you put it upside down on the table (e.g. foam, a pillow/cushion
-LCD screen cleaner and a lint free cloth.
-CR2032 Battery
An anti-static wrist-strap is strongly recommended if you have one. If not, make sure you're not wearing manmade fabrics (e.g.
nylon), and ground yourself to something earthed regularly when you are working on the M3 module.
5 Replacement of touch-screen:
5.1 Remove the M3 module from the keybed (M3 with keybed)
Disconnect the module from the mains
Disconnect all connections from the module (inputs, outputs, damper etc.)
Disconnect the module from the keybed (mini-din connector on bottom of module)
Unscrew and lift off the retaining bar above the keys (4 screws on M3-73, not sure about other models):
Detach the LH1 bracket(s) from the frame at the rear.
Lift the module clear of the keybed.
**There is no film on the touch screen to be removed!
