Cause

  • Plastic gears in the module latch system have stripped or plastic latch system is broken. 

Resolution

  1. While putting pressure on the T-handle or 1/8th inch Allen wrench, turn the gear slowly to the left to see if the module will unlatch.
  2. Try wiggling the tool up and down while turning to the left to see if that will unlatch the module.
  3. If you are able to get a module out that is beside the stuck module, you can try to unlatch the stuck module from the rear. It will take a short T-handle or Allen wrench to access the gear from the back of the module.
  4. If the module cannot be removed or surrounding modules cannot be removed for rear access, contact Daktronics Customer Service for support.
