    Default NES (frontloader) video interference issues - not RF related

    Howdy folks,

    I just picked up a spare NES at a yard sale today. Just tested it out, and it works - took some doing to get it to actually boot a game, but I expected that as it probably needs a new 72 PIN.

    The issue i'm having is there is wavy interference in the picture - during both a/v and rf output, so it's not a case of it being a bad rf connection. Compared to the existing NES I had hooked up, which was crystal clear. I'm using an official NES adapter in both tests.

    Is there a fix for this or is the console fubared? I have a sinking feeling I know a possible cause - the dude was using some sketchy offbrand adapter to power it. It said the output is 10v but the NES clearly states 9v - although I've read the NES can tolerate between 7 to 12v. But I dunno.

    Anyone have any idea about this?

    Thanks!


    EDIT: Took the sucker apart and noticed a glob on the board underneath the shielding on the modulator unit (where the a/v and rf ports are) Is this evidence of a capacitor leaking or is it supposed to be there? I took a pic:
