EVAL-ADV7842-7511 Noise Interference lines

Hi, I have a EVAL-ADV7842-7511 Board which I'm using to decode CVBS signal from a Laserdisc player.

I have an issue where I'm seeing faint diagonal lines across the image. These are present on all of the input formats 10Bit, 24Bit and 36Bit and is also present on the s-video input. 

It it looks almost like interference. I've tried multiple cables and players and all produce the same results.

Any idea what is causing this?

many thanks

  • I'm still not having any luck running input scripts via AVES Blue. Still getting interference lines.

    Also if I wish to control the 3D comb registers through Terminal is this the correct way to input commands? For example, if I wish to run SDP_3D_COMB_EN, Addr 90 (SDP), Address 0x12[0]   do I type:

    wri2c 90 120 0    to disable 3D comb

    wri2c 90 120 1    to enable 3D comb

    Apologies but I'm a novice. I'm unsure if I include the number in the square brackets [ ] or not

    Thank you for your help
