VCR Guts

About an hour ago I attempted to hook up a VCR but for some reason only the audio was playing out of it with no video, so I grabbed another one but this one wasn't taking the tapes in, it would spit them back out every time I tried to put one in. Sooo, being the mechanical tinkerer that I am I decided to check out the insides and see what I could do. I've built my own PC, opened up laptops, and even VCR's in the past, normally just to look around never to do any work, so I figured it was worth a shot.
The first one I tried to work on was the one that wouldn't take tapes in. I took it apart piece by piece, I wish I had taken pictures of the process but I was so engulfed in it I didn't even think to do so. After messing around with it for a while I got it to take tapes in but when I tried to play them they were all static-y. So I decided after almost an hour that this one was garbage and tossed it out. I opened up the next one and started fiddling around, and what do you know all I had to do was push in a little piece of metal attached to the RCA out jacks and the video started to work! Eureka! I felt like a VCR mechanic, if those even exist. So good times over all, got to play with the insides of two VCR's and finally got one working, check out the video to see how they work inside if you have never seen it.
