Here it is please note that the rainbow is rolling very fast downward. And I adjusted T704 maybe a half turn both ways.

and the fine tuning does it do like in my video, gets dark and lose sync.

you are prob ok on T704 deal with it later.

If I turn the fine tuning all the way clockwise I lose the rolling rainbows. Turning it all the way ccw I lose sync.

[DaveWM]

are you sure you are on the right channel? that sounds backwards on the fine tune like you are off one channel. Try going up or down one channel from where you are and fine tune again. CW would cause you to lose sync.

Well I went one channel down and I dont lose sync at all but I lose the rolling color bars when I turn all the way ccw. The rolling color bars get a lot brighter when I turn the fine tuning all the way cw. Now on the upper channel when I turn the fine tuning cw I lose sync only after about less than a quarter turn note that I am starting from all the way ccw.

[DaveWM]

something is not right, you should be able to lose sync. I assume you are using the standard 3-4 channel output converter box?

Ok I just checked mine, the CTC-7 tuner is a bit different than the one in the video(video has tunable slugs for each channel, ctc-7 has a VC that effects tuning on all channels), so its possible that you may not lose sync (mine did but just barely).

but it was def fully CW for loss of sync and CCW I would lose color sync (rolling bars) on my CTC-7.

triple check what channel you are on and what channel the output is, but IMHO you need to be on the channel that has fully CW for loss of sync/dark pic.

You may have a problem with a converter tube in the tuner, OR your AGC may need to be adjusted.

confirm the channel and fine tuning operation 1st

then try a different converter tube in the tuner to see if that makes an difference.

lastly will adj the AGC, I did not want to go there since the CTC-7 has a different approach to that than later models, but its not a big deal and you can aways reset to the orig starting point.
