Probable Cause
Poor cable connection
Corrective Action
- Check the cable connection between the display electronics and the lower control board.
- Inspect the cable for any nicks, cuts, or pinches.
- Ensure the pins are not bent or broken and are making a good connection. If necessary, using a fine-pointed object close the female pins so that the two sides are touching one another.
- Using an ohmmeter, verify continuity through the cable. Replace cable if necessary.
- Reset connections and retest unit.
