I am getting black and white output even after enabling 75% color bar test pattern in ADV7391. (PAL Video). Please find attached Color_test.bmp file.
Can you take a quick look at the video signal and see if the color burst is present. It should be a small 19 cycle 4.57MHz signal riding on the video signal right after the hsync pulse. Also check to see if the video has the color carrier on it.
Thank you for your reply. Please find attached video waveform screenshot.
This has the color burst present and the amplitudes look correct.
What sink are you using?
Can you try a different sync?
I tried with different sync but still I am not getting color bar. This issue is with PAL only. For NTSC I am getting Color bar.
What sink (monitor) are you using?
- I am using Sensoray to capture video
- display is dell monitor
Which specific monitor and video capture equipment? Make sure they can work with NTSC inputs.
Video capture equipment is working with NTSC inputs but its giving me black and white test pattern output for PAL inputs. For ADV7393 its giving me color bar output for PAL but for ADV7391 its giving me black and white test bar pattern.
