Korg Electribe EMX-1 Booting fail After Powerreplace

Hello, I bought a Power Board KLM 2366 here on the website. Have it goods were newly manufactured by the manufacturer according to description.

After switching on and during the boot

Immediately a message appears: “F1System MsMath”

I can’t find any information about what it could be.

Does anyone have an idea?

I asked chatGPT for an answer!

The Electribe EMX-1 (Electribe MX) uses SmartMedia and has a few known boot / display / error failure modes, so here’s a short, practical troubleshooting checklist plus what those failure modes usually mean.

Quick checks to try now

  1. Press STOP / CANCEL to clear the message (the manual says most error messages clear this way). ManualsLib

  2. Remove any SmartMedia card and power the unit on again. Faulty or unreadable SmartMedia commonly produces strange errors. If it boots OK with the card removed, try reformatting the card with the EMX (or use another card). ManualsLib

  3. Power-cycle (turn off, wait 30s, turn on). If the display is garbled only sometimes, this can recover it temporarily.

  4. If you still get weird text during startup, try the factory preload (this reloads the factory data): hold Transpose (Solo) + Write while turning the EMX on; the display will say Preload and PLAY will blink — press PLAY to load. This takes ~30s and will overwrite user patterns (back up first if you can). ManualsLib+1

Possible causes (what that odd string likely points to)

  • Display / firmware corruption — garbled messages often mean the display or the firmware that drives it is struggling. cdn.korg.com

  • SmartMedia / Card read errors — bad media can interrupt the boot/data routines and show unusual errors. ManualsLib

  • Power / hardware faults (aged capacitors, blown protective chip/fuse, failing regulator) — EMX/EMX-1 units commonly show blank/garbled displays or fail to fully boot when a small power board/component fails. Users report symptoms like blank screens or “AllFl Ld” after replacing fuses or when power components age. If you see only the backlight or see odd characters, this is a suspect. forum.vintagesynth.com+1

  • Encoder / control issues — if the unit behaves oddly when you turn knobs or the wheel, the encoder can be dirty/failing and cause strange UI text/behavior. Cleaning or replacing the encoder often fixes it. Reddit

If the quick fixes don’t work

  • Try the Preload (factory restore) step above (back up first if possible). ManualsLib

  • Inspect power connector and internal fuse (do not open the unit unless you’re comfortable; if under warranty or unsure, contact service). There are known EMX-1 repair threads about blown fuse chips and blank screens. forum.vintagesynth.com+1

  • If you’re not comfortable opening it, contact Korg service/support or a local synth tech. Korg’s product/download/support page for the Electribe series is here.

  1. stop or cancel dosn‘t work

  2. I removed SMC, by power on it is the Same

  3. When the Massage Shows non of tip-combobation work

  4. Preload/ Factory→ Solo+ Write → dosnt work,

  5. Erase+ pattern → Working

    → Test of Encoder, Buttons, Display Test 100% functionality

  6. SM-Test Shows errors

Hello,

A shop tried for me to replace the KLM-2366. They get an error because my EMX was a Smart Media and the PCB was for SD version. The CPU is programmed for SD or SM version, if you mix the 2366 PCB it won’t work (need to flash the main CPU and KORG do not share the procedure to realize it). I don’t know if it’s your case, but it may help.

I’m looking for KLM-2366. If you know where I can find one … (but not at 400€ :’))

See you
