I don’t think I can test the tv without the vcr working. I believe something in the vcr part is causing it to go into Safety turn off. I’ve tested most of the resistors. I’m waiting for a desolder tool to pull the capacitors off the board to test them. I was told I can’t test them while there on the board

I have nothing on model "WF319E". But I'll bet I've seen its ilk many times in other brands (Funai, Zenith, Magnavox). Anyway....
My ears immediately perked up when I saw your video of the deck trying to load a tape that wasn't there. So, that's why I asked you what would happen if there WAS a tape there.
Maybe from what you've told me it could be an tape-end sensor problem.
Funai did have a problem at some point (and I don't know if it involves this model, or not) where the tape end lamp LED (the transmitter) would need to be replaced. If I recall there was a modified part available to solve some problem in some model(s) involving that LED and what I think I'm seeing in your video could have been the symptom.
I don't know how to tell you how to check the lamp. It's IR (infrared) so you won't be able to see it. With very careful aim the camera in your phone may be able to detect a red spot coming from each side of the IR end lamp (one that comes, and goes away as you power, and unpower the unit). I might also expect, I don't know, 1.8 - 2.5 VDC as measured on the two pins of the LED on the circuit board.
Each of the two tape end sensors (the receivers) should be reacting to the light from the LED. I would think you should be able to see voltage change on the two pins of each tape end sensor as you effectively block, and unblock the IR light of the sensor.
I don't really know what else to tell you without being there to see it. It's been 30 years since I worked on this stuff. I hope I'm not leading you off in the wrong direction. Good luck.
