Everything points to that this should work, it's just an old fasion NTSC monitor! But nooooooo.
As you know, the Zapper works by flashing the screen black with a white block for a target.
But this act on the C64 monitor makes it lose vertical hold for a little but, and thus makes it impossible to make a shoot.
So, any ideas?
adjust your v-hold knob. youre probably out of adjustment enough for it to keep sync while theres a bright image onscreen but to lose it when theres a dark one. i've seen this happen before.

V-Hold was adjusted in every possible position, it bounces no matter what.
Think about a capacitor replacement job on the monitor then? I've found the Commodore-branded monitors are terrible on the vertical hold past a certain age. I think you'll find the problem is unique to the monitor, as opposed to a problem with the NES; try a Master System or anything else that flashes the screen for light gun action and you'll probably get the same result. Not sure if a cap job will fix it, but it can't hurt.
