Exercise Bike LED Display Faults – Driver and Backlight Issues

Are parts of your exercise bike's LED display missing or dim? This guide explains issues with LED driver chips and bad solder joints that cause these faults.

How LED Segment Displays Work

An overview of how a driver chip controls individual LED segments to form numbers and letters.

Symptom: Missing or Dim Segments

The classic sign of a display fault, where numbers are unreadable because some LEDs are not lighting up.

Cause: Failed LED Driver IC

The integrated circuit (IC) that controls the LEDs can fail, causing whole sections of the display to go dark.

Cause: Bad Solder Joints

Vibration can cause cracks in the solder connecting the display to the board. A technician can often fix this by re-soldering the connections.
