I was given two VCRs today

[vintagevcr]

Today, a woman (who has bad luck with VCRs apparently) gave me two VCRs to look at. One of them is an RCA VR-519. With the cover removed, I plugged it in. It quickly started making a loudish clicking sound. I noticed the main cam seemed to be making that noise, and it looks like its trying to move.

The other VCR is a Symphonic 6300. At first I thought it was dead, but it seems the display just won't light up. I tried putting my test tape in, and it loaded the tape around the drum, but I got no picture on the TV. I was about to give up, but then I realized it might be the tape. So I put a pre recorded tape in, and to my surprise, it started playing! The picture quality isn't that bad for a two head model either.

Would anyone be able to help me fix the clicky RCA, or get the display working on the Symphonic?
