Overview

Issue
Dots that don't change or move, also known as dead or stuck pixels, appear in the projected image. Changing the video input source on the projector doesn't resolve the issue.

Symptoms
Cause
Solution
Check the connection to the input source signal.
  • If the connection is good and the dead or stuck pixels remain in place, please contact SMART Technologies to process an RMA to repair or replace the projector.
  • If the dead or stuck pixels move rapidly, resembling "snow," check the input source signal and cable connection quality.
Disconnect all inputs from the projector and check if the dead or stuck pixels appear on the blue screen with the white SMART logo on it. If the dead or stuck pixels appear on the SMART logo screen and if the projector is under warranty, please contact SMART Technologies to process an RMA to repair or replace the projector.

Background
A small percentage of all projectors, including projectors from manufacturers other than SMART Technologies, can experience this dead or stuck pixels issue. As part of SMART's commitment to quality, we're always improving our projectors to significantly reduce the risk of this issue occurring. Consequently, this issue is more likely to occur with older projector models. SMART promptly repairs or replaces any projector that experiences this issue within the warranty period.
