It is a pal signal I should have clarified that. the signal integrity is seemingly fine. all the TVs and converters display some picture but very dim. Unfortunately I don't have access to a better scope. | |
| Mar 9, 2023 at 16:46 | comment | added | Justme | I don't think the scope has enough bandwidth for properly seeing the composite signal. I assume that is PAL? The sync pulse seems to have correct amplitude, but the front and back porch of black signal is somehow just noisy. But it might be that the scope just can't handle that fast signals, so it might be OK after all. In practice with a better scope it might be possible to debug better. | |

I am also certain the blue has nothing to do with the optical part it was sort of a reference point. | |
