NES (frontloader) video interference issues - not RF related

[ApolloBoy]

That glob you see is just hot glue that was applied over the coils in the RF box to hold them in place. However, I would definitely suggest changing out the big 2200 uF filter cap in the RF box, it usually causes problems like that when it's on its way out.

I have had this issue before in two different NES'es. The 2200UF electrolytic cap was the problem both times. Replaced them and they're back in business.

Ah okay. I'll try replacing the capacitor then.

Thanks guys!

Wait, the video output isn't supposed to be wavy like that? And all you need to do to fix it is replace the 2.2 mF capacitor on the video output? I've got to do that!

All if not most nes consoles i worked on i had to replace the caps.
in the rf box not a easy job but would make life easier with hot air tool.

but would make life easier with hot air tool.

That's a sure fire way to lift some traces.
