Potential Symptoms

Cause

  • LED failure on the digit or segment.

Resolution

  • Replace digit or segment that has LED outage.
    • LED displays have a current expected lifetime of 100,000 hours (about 10 years), after which they will be half as bright as when the display shipped. This is not a failure of the display but rather the natural properties of an LED.
    • Replacement of multiple digits or segments within the same display may be desired, as the brightness level of one or two replacement digits may give the display an uneven look.
