I have an NES that I'd like to try and repair if possible. This is my tried and true NES since I was a kid. About a year ago I bought a new 72-pin cartridge connector. Everything thing was working fine and then I was met with a loud buzzing sound with no audio or video when I turned it on. The cartridges weren't staying down so I had to go in and tinker with it bit. When I opened the console up a second time I was removing a screw (circled in red) and my screwdriver got stuck to the side of the metal. It was brief but I felt a tug on the screwdriver. I immediately removed the screw driver but since then I've had the buzzing sound issue and no video. Since I've gotten a bit better with repairing older consoles I wanted to take the time and see if I could bring this wonderful relic back to life.
1. Went in to replace the 72 pin connector.
2. Screw driver briefly got caught on to the metal piece circled in image #1.
3. No more audio/video
4. Buzzing has been significantly reduced but still no video/audio.
