    I would try partsstore.com but they are very exspensive. probably be better off trying to find a used CRT.

    You have to use some insulated pliers then slide the rubber boot back then grab the wire and turn it 90 degrees and pull it out of the splitter. As soon as you remove the wire ground it to the metal chassis to discharge any stored voltages from the CRT. Do not remove the wire from the CRT itself as any replacement CRT has the wire already attached. I may have found a used green CRT for you I will know this afternoon for sure.

Re-insering the flyback wire is usually very easy. Push in and give a slght turn and check to see if grabbed. It sounds as if there is more issues than flyback wire. TV should turn on without one crt connected

Red CRT is doing short circuit in the neck. You can try to open the front panel and to hit easy the neck with wood or something and to decrease the red screen a bit. If doesn't work then replace the CRT.
