THS7347: THS7347 +AFE1000+DDP4421,When VGA Input,stripes will appear when the blue background color is displayed.

Part Number: THS7347

DLP Using THS7347 +AFE1000+DDP4421,When VGA Input,stripes will appear when the blue background color is displayed. The digital 、analog power & GND  is not separated. When HDMI Input HDMI input does not appear.

In the previous version  Use  combination of multiple boards And Use the same schematics and software., there was no such stripes when  blue background color is displayed .

  • Hi Yue,

    To better understand the problem:
    1. Would it be possible for you to point out in the color image as to where exactly you see the stripes appearing when the blue background is displayed?
    2. Also, would it be possible for you to attach a clearer image of the schematic?

    It might also be good to know what video standard or picture quality that the customer is using the THS7347 for. An example of video standard would be 1080p60 or Full HD, and likewise.

    Best Regards,
    Rohit
