All the magic smoke escaped. Too bad.

[JoeNewberry]

Why plug it back in just to make it smoke some more?

I believe I know who this man is. He is one of us.

One of us, one of us, ONE OF US!


I think that's Dan (ctc17)

Figure what's done is done. If its on its way to failure obviously there's not much you're going to be able to do about it. If the fly internally shorts or arcs its near impossible to fix unless you're really good at unwinding transformers.

Did you watch the follow up video of replacing that with a packard bell flyback? That chassis has also had a full alignment and has an awesome picture.

Unwinding 'em isn't a big deal. Rewinding would be the challenge. Has anybody ever successfully rewound a color flyback? Or a B&W one for that matter.

[jpdylon]

yeah, I did. It really does look awesome.

Here's one with a cap in a set letting itself go. (same person)

I am *the* person. And I am not afraid of anything.

As far as the videos go, I always have the camera sitting near any set I am working on. I love smoke, arcing and fire. If the flyback is internally arcing, may as well let it finish off.
I try and go a bit deeper into the restoration of the old color sets. Alignments, substitutions of no longer available parts and other 'taboo' areas.

Im just getting started with the video thing too. Expect lots more smoke and detailed how to videos.

[Bill R]

I like the videos. There is a lot of good information in the service videos. If a part is dieing i'm ok with it, since it will have to be replaced anyway why not have some fun.

It's all fun and games, till that ailing flyback shorts B+ to ground and takes out the PTX as well...

But that's not likely to happen in an instant, it would take time, enough to pull the plug most likely.

I would be a little worried about the venting can capacitor though, it could go bang.

I think that'd be my concern. I'd worry about further damage being done by just letting it run its course. When something starts arcing, smoking, sizzling, or glowing with the power of many suns, my first instinct is to unplug it and not plug it back in till I fix the problem.

Still, I can see some benefit in showing those things. Deters the curious from trying something dangerous just to see what happens. As the Mythbusters say, "There, we've done it, now you don't have to try it at home."

like you Alignments videos very much. very unique and instructive. could you do a series step by step on of how to align ctc 16 if you have that type of tv?

I do have a 16 and will get to it after I get more practice. The 16 and 35 IF is basically identical.
Its amazing how everything falls into place when aligned. No buzz in the sound, the sound, color and video track right with the fine tuning. The tint control is centered and the color looks good.

There is no one to teach me how to align sets, I have to learn by reading and doing, trial and error. I bought the estate of a 'master aligner' and have tons of material to read from manuals to magazine articles he saved. I have lots of these late 60s particle board consoles and a few can get sacrificed so we all have a reference how to make them work their best.

On the power transformer thing. I know the older sets are much more fragile but these late 60s/early 70s power transformer are super robust.
First the damper would melt down then the choke would burn up the the circuit breaker in the houses fuse panel would blow. Thats assuming you bypassed the fuse or breaker in the set.
