Famicom isn't working and all I get is a glitch screen, any help would be apprec

[77punk]

Below is a glitch screen from my broken Famicom and I am just wondering if this is a tell tale sign of anything in particular. I have about 60 games and spent many many hours trying to get this system working before I cracked and bought another one and all the games work flawlessly. Any information anyone has would be great to try to get this system up and running as I love tinkering with this kind of stuff but I am at a loss. Thank you peeps!
