PiZero Powered through CRT Components?

Greetings all! Long time lurker and love to read everyone's projects, discussions, and debates.

I finally picked up a PiZero (camera edition) because I want to recreate the CRT Raspberry Pi project featured here at Element14 with my son (5 year old). This was his idea as I started going around browsing and he hasn't stopped talking about this since . Ideally, I'd like to use the circuitry from the CRT to power the Pi so I only have one power cord. I'm using a Sylvania SSC192 which has a VHS player on it. From what I see on the schematics, it looks like there is a 5V point available. Is it safe to solder onto this point and not damage the Pi? I will have an additional switch in place so the Pi doesn't have power running to it 24/7.

I appreciate the help here, thank you!

Officially there is a fuse between the power input of the pi and the rest of the pi. By connecting something to an internal 5V point you are circumventing that fuse.
IMHO that is not that bad. If the power going into the pi is limited the options for big mishaps are similarly limited.

I would personally not solder directly to the pi except to mount the 40 pin header. I would then put a connector of sorts on the header.

There is a poly fuse for Pi3 and co, but I thought there wasn't any for the Pi Zero?

You could be very right!..... In that case, the foundation is accepting my view on the issue: there is not much trouble that this fuse would be preventing. :-)
