Just picked up a Panasonic PV-1730 Hi-Fi VCR

Do you have a dummy test tape to put in it? A tape shell minus the tape and innards? So you can run it through its paces without ruining a tape.You're finding out about the complexity of those machines.

With all of this in mind what might be wrong with this VCR and can it be repaired easily?

Without a service manual to check voltages and signals it will be difficult. Could be a reel drive IC. First thing needed is to check all power supply output voltages.

I have some photos I'll upload as soon as my google photos account starts to cooperate again, because right now its not loading correctly for some weird reason.

Why bother with Google? Just upload the images to the Videokarma website.

Well the problem is the pictures were taken with my phone, and using Google photos is the only way I can get the pictures from my phone to my computer without having to mess with my phone's microSD card.

As far as sacrificial tapes go, I have some old blank tapes that were NOS that someone gave me that I can use for that purpose, and the VCR seems to be in a "lockout" mode as it won't let me load a tape into the VCR and without the VCR being able to power on it won't allow me to load a tape into the VCR.

I never do it that way so can't help there. I use either my Canon or Nikon cameras for my pictures.

You MIGHT be able to trick it by turning the TU reel by hand when you power it on, which should send a PG signal to the microprocessor.

Other than that, without a service manual and putting it on a bench to check things with an o'scope and DVM, don't know what to tell you.

Ok. Let me try posting the pictures onto here from my phone.

Well unfortunately when I was trying to remove the take-up reel assembly I ended up having one screw that happened to be torqued down too tight at the factory (which seems to be the case on every single VCR I work on) and when I was trying to unscrew the screw I ended up stripping the head out (because they used brass for the screw rather than stainless steel or some other harder material) so now I have one screw that's stuck in the take-up reel assembly and I'm able to get it out without having to resort to the possibility of having to drill it out.

What have you guys done in situations like this?
