That's likely a technical certificate through a community/junior college, yeah. I can't imagine anyone offering an associates specifically in TV/VCR repair, and if they did, it was one college's hairbrained idea that held little weight outside of their immediate market.
I know a couple of guys who run a VCR repair shop in Wisconsin. They mostly just sit around and talk about movies instead of repairing VCR players. In fact, I don't think they've repaired a VCR player since the 80s. Not sure how they're still in business.
I have zero training in that stuff, but I'm occasionally called upon to do it for my library's digitization service. It's kinda fun! Anyway, if you DO have some kinda certification in that, your local public library needs you.
95% of VCR repair is changing belts and cleaning heads/pinch rollers. I should hit up my local library. Those are the causes I like donating my time to.
