Panasonic AG-1980P - Diagonal Lines in certain colors.

[ENunn]

i've been having this issue for a while with my 1980, where in certain colors (mostly skin tones, reds, and yellows) there's these diagonal lines and i don't know what's causing it. it used to be really bad, but swapping out my s-video cables with some good ones fixed a lot of it, but some are still there. i run my vcr through either a datavideo tbc-3000 or a panasonic dmr-es15 (depending on the tape). i can filter most of it out with some denoising in avisynth, but sometimes it'll still show up slightly. i have my vcr set to edit mode. i haven't tried norm or detail but i'm not a fan of those because of the ghosting so I avoid using them.


i had a similar issue with my now dead jvc hooked up to my es15, but that was much much worse. but i think that was caused by the cables i was using.


it doesn't show up all the time but it seems to only show up when the tape has hifi audio, and even then it doesn't show up on all hifi tapes either. is there a fix for this? could it be my caps? i don't see why, they've been recapped. i posted something about this on a discord server, and someone mentioned it looks like something called hifi leak. i don't know how to fix that.

What is your capture card / digitizer?
Electromagnetic interference? Mobile phone or similar near by?
Ground loop?
Is it in the luma (Y) or chroma (U,V) channels?
Do you get the same disturbance when connecting the 1980 straight to TV via S-Video or Composite?

nah, just my capture pc, my monitor, and my crt tv. i have nowhere else to put them.

Ground loop?

i'm not sure. i have everything hooked up to a ups.

Is it in the luma (Y) or chroma (U,V) channels?

how do i find that out?

i'm not sure. it's hard to tell with a 14" screen.
