op-1 wont turn on ... leds flash

edited October 8 in OP-1
I was in the sound menu eith the low mid high and turned around the knobs until the bars were not miving and more.
then i was in the normal keyboard mode and the knobs did not do andthing anymore.
so i wanted to turn off and on the unit.
but its not turning on and more.
the screen is black and the charching lights are lighting up one after the other from bottom to top.
i tryed pluging it to the charger and turn it off and on again but it stays that way.

any help?


  • Can you access the TE BOOT menu (Hold COM while switching on)?
  • Thanks for the reply. No I already tryed that. It does not really turn off. No matter in what position the on/off switch is the leds always light up from bottom to top one after the other snd the screen stays dark.
  • How long did you let it charge? If the battery is drained, it takes some time until you see any lifesigns (battery charging LED animation). Let it charge at least a few hours, using a dedicated USB charger (PC USB port may not suffice).
  • After battery drained I can turn it on again. I did a full reset, but the charging lights are broken ...

    The flash sometimes. but not when op is turned off.
  • Try recalibrating the battery. The next time the OP-1 goes dark because the battery is empty, don’t switch it off, but charge it for about 6 hours with the power switch set to ON. Then the battery meter should work correctly again.
  • ah ok, perfect! i ll try
