I have suspicions that a repro cartridge damaged my Nintendo 64

I have blown into the cartridge slot and the cartridge many times, and I have also made sure it wasn’t the jumper pak. It never did anything like this until I put that cartridge in. Just by looking at it I had a gut-feeling it wasn’t a legit cartridge but I tried playing it anyway because I thought it would be fine so long as it worked well enough. Unfortunately it didn’t work and I just assumed the cartridge itself didn’t work, until I put one of my other games in, which as far as I know are second-hand copies I found in resale shops and they all have worked fine in the past. The Nintendo 64 shows that it’s turned on but no picture or audio goes into my TV. I guess my mistake here was that I just bought this cartridge online. I was hoping if there was anything I could do to fix this issue, because I really don’t want to have to buy a new console. I know I could just emulate these games or play them on Nintendo Switch Online, but to be honest I like playing on original hardware because it’s more authentic.
