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, so 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.
