Chosen Solution
Hi guys, I just installed my whole old “NES” set yesterday on a CRT screen i got free from some folks.I wanted to play Duckhunt with my Zapper gun (which i used some years ago) and i couldn’t hit any Duck on screen.The Zapper gun clicks and the screen flashes, so my shots are registered (i guess). I tried to clean the gun from the inside (lens and laser with a dry cotton stick), but that didn’t do the trick. Is there any other solution i can try besides cleaning?Or do i need to buy a new Zapper/replacement laser?EDIT:Posted a few pictures for @oldturkey03
Joeke let’s assume for now that it is not your TV and that the CRT does exactly what it is supposed to do. In that case I would think it is the light sensor in the “Zapper” Post some really good pictures of all the internals with your QUESTION so we can see what you see. You want to check the switch with a multimeter and make sure that it works. Hopefully we can find something to help you out. Adding images to an existing question
I remember years ago there used to be some sort of calibration in the games.
