DLPC2607: Noise Issue.

Part Number: DLPC2607

Dear TI Team,

We are developing products using DLPC2607 and PAD1000.

I have an issue such as the one below.

1. Noise will appear on the screen when displaying a certain pattern.

2. It does not occur in all PCBAs, but occurs in certain PCBAs.

    About 15 out of 400 occur.

3. If you replace the PCBA, the noise symptoms disappear.

4. We have confirmed that there is no unusual result as a result of checking the voltage and driver.

5. Please note that I attach a picture with noise.

*Can you check the cause and the debugging point?

Thanks.
