Hi User,

Yes we have seen this issue, It happens when proper power down procedure is not followed, Which risk the DMD lifetime.

If proper power down procedure follows as per the datasheet, it can reduce the risk of DMD lifetime.

See page 6, pin PARKZ and page 45 for power supply recommendation here : http://www.ti.com/lit/ds/symlink/dlpc3439.pdf

Thanks,

Navneet
