Is shielding restore worth it?

[fisher]

Hi, I just got an old Atari 2600 V16 board fixed :-)

Although it plays fine, it has a lot of artifacts on screen.

I think it may be interference generated by it's circuits, since it has no shielding on the processor part.

Would be possible to rebuild the missing shielding?

How could it be done?

Would this make some big difference?

Thanks in advance.

How is your video connected? There isn't any artifacts usually caused by the circuits unless there is some missing filter capacitors, etc.

 

If it's RF, then it can be helped with ferrite beads and/or better cabling.

It's by RF.

I'll try to find a better cable for it.

I'll also look for some homebrew ferrite beads, any suggestion for a good and easy way to do it?

75Ω cable from antenna (RG6) don't seem to fit, but it's what I have laying around.

Maybe I should do a composite video mod to it, but I just don't want to do any holes on the case.

So the missing sielding should not be the responsivle for that, interesting.

I hope this helps here's a video I made not long ago. I'm new here anyways!

Thanks!!
The image is slightly better now.

I changed the cable, now it's a piece of a satellite receiver coax.

A little tight fit, but it's working fine.

I still have some wavy lines on TV, but the differences of before and after are just like comparing day and night!!

It is 2016. Get a Composite or S-video mod.
