Did you adj the fine tuning per my video? Try it while doing what ever you are doing to get a BW pic

the idea here is to isolate the color issue to tuner bandpass or color circuits.

i did adjust the fine tuning. i have to push on the tuner though for the picture to come in clear. its working again, black and white but something is up with the tuner.

Rob,
If you're on channel 3 with the VCR, try switching it (or changing it in set-up menu) to channel 4. Then change the TV to 4 . Or vice-versa. its possible your Motorola's tuner may not have the fine tuning range on the channel you are using. If you have to push the tuning knob in for it to come in at all, wiggle the tuner tubes or the tuning knob to verify if you have a connection issue.

You're probably doing the TV a favor by letting it run. It needs to get warm to get the dampness out of the electronics.

You're getting there. It's got a picture!!

Well that piece isn't a magnet, it's the degauss thermister, and yea, if it is open or in this case falls apart, set will be dead. Maybe the tubes may light up, but no B+ to operate the set. If you like to try it out, just twist the loose wires together and see if the set powers up. Usually it's a 120 Ohm thermister (cold), and it drops in value as it heats up. Giving the set a slower warm up and also runs the automatic degaussing. Also check for a large black round varister with 2 leads in the degauss circuit, usually near the thermister. If it is fried, it needs to be replaced as well. Set will work with out it, just won't degauss the crt. I have a 120 ohm degauss thermister if you need one. I'll send you it free.

Sorry, only read first page of post, didn't realize you got the set going.

Here's an ad from Sep. 1964 when Motorola introduced these sets:

Love that ad link - but check out the Admiral "Copenhagen" ad on page 65!
