I’ve had my unit for 10 years and after 112 hours of use, it’s been rendered useless.  When I turn it on, all the lights come on and then the L747 message appears on the led board and the unit locks up.  I love this light and have really enjoyed having it as a part of my light show.  I’m a mobile DJ and would love to have there light back working again.   Please help!

Hi,
It is possible that this light may be set to Slave and/or Blackout Mode.
Can you verify that you have this unit set to Master?

  1. Press Menu until "SLNd" is displayed and press Enter.
  2. You will then see one of three options - "MStr", "SL 1", or "SL 2" - make sure "MStr" is selected. Press Enter to confirm.

Also, make sure that the Blackout mode is off by doing the following:

  1. Press Menu until you see “bLNd” being displayed and press Enter.
  2. You will then see one of three options - "Yes” or "No" - make sure "No" is selected. Press Enter to confirm.

Let me know what your results are after trying this.
