HELLO

We're having some problems：

1.Operating current is 0.165a on 12v power supply, but no image is displayed.

2,When I switch the source, the optical module flashes, no light comes out,

3. When selecting the DLP Logo as the display source, DMD does have the image although it is not projected.

I hope to get your help on how to solve these problems！

    Hello Ross -

    When switching the display source, the optical module flashes but never casts any light.

    After the module flashes, the error history is read as follows：

    Of course, we can also find the results of ADC Measurements.

    So why doesn't the optical module display the image?

    Thanks，

    Hello Xia Yang -

    I am worried that your module may be damaged. You may need to submit a "EVM Return" form so you can return the EVM to TI and we can send a replacement. Are you okay with this approach. I will reach out via email to send you instructions.

    Regards,

    Ross
