Both LVDBs Fail When I Plug In A Row of Mods

Potential Symptoms

  • Mods all flashing 3's.
  • LVDB's making a "clicking noise".

Environment

  • VF-XXXX
  • LVDB

Cause

  • There is a bad module

Resolution

1. Unplug all mods from LVDP.

2. One at a time, plug each row of mods into the LVDB until you find the row causing the failure.

3.Plug all rows back in except for the failed row.

4.Unplug power from the back of all the mods in the failed row.

5.One at a time, plug power back into the back of each mod until you find the bad mod.

6.Replace bad mod.

Work Around

  1. If you do not have spare mods, move the mod to an area of the sign not being used and leave unplugged.
