Good afternoon LinYing Guo,

I see that you made another E2E post (https://e2e.ti.com/support/dlp-products-group/dlp/f/dlp-products-forum/1532643/dlp9500-dlp-products-forum) regarding the DLP9500 and seeing abnormal horizontal strips (bands) on the DMD. I do not know if there is a correlation between this bad pixel and the horizontal bands you are seeing on the DLP9500, but I would recommend following the recommended steps from that other E2E inquiry you have posted to see if those steps resolves this issue.

Thank you and Best Regards,

Tristan Bottone

Hello LinYing,

The DLP9500 data sheet shows the following specification on page 23:

The DLP9500 DMD can have up to 10 non-adjacent non-operating mirrors. This DMD is within specification.
