RCA Trans Vista CTC44A

[Sean730]

Hi all!

Been a bit of a fly on the wall member for a little while. Just recently acquired this RCA CTC44A "Trans Vista" 25" model. Got it for $40 delivered. The guy who sold it to me said it belonged to his aunt who purchased it new and he inherited it upon her passing. The cabinet is immaculate on the outside, and after a bit of air dusting the inside, its remarkably clean. I went ahead and plugged it right in, gave it a few minutes to "warm up" (it's an instant-on set). Flipped the On/Off bar and voila! Came right on. Fed it a signal from a Comcast "converter" box and got a picture! And not a bad one for what its worth. But when flipping through channels, I noticed that the picture had a slant to it. From the top left of the screen the picture slants down to the right. You can't really tell when the picture fills the whole screen, but letterbox format made it all too obvious. I have attached pictures to show what I'm describing. Any suggestions? I'm fairly new to the TV collecting scene so to be frank, I'm not entirely sure what I'm doing...

Thanks to all in advance!

Here are a couple pics of the set....

easy fix.the yoke is crooked.loosen it up and straighten it

1. Take the back off the TV and carefully clean it, a vacuum cleaner and a paint brush to loosen up the dust works nicely

2. The "yoke" could be crooked.. on this kind of TV it's probably held to the neck of the cathode ray tube with a metal strap and a set screw... if you loosen the set screw, you can rotate the "yoke" a little, and then tighten the set screw... don't tighten it too much though, it's clamped to glass. Do this with the TV off.

3. Nice TV... welcome to VK

4. "instant on" means unplug it when you're not using it, or defeat this feature.

It might have that yoke clamp, that rusted and cracked. I think it was a reaction with the rubber coating. Or was that the purity, blue lateral assy.
IIRC, the CTC44, was less common, than the CTC40.
Great find!

Thanks for the info everyone, I will take a look at it this afternoon. And yes Max, I intend to kill the power to it entirely when not in use. I presume a Comcast cable box with a switched AC outlet is acceptable, as I was planning to have it hooked up to one and just power the box on first and then manually flip the on switch on the set. I will post my findings later on!

Man, that's a beautiful set. Back in '80 when I was selling used TV sets out of my college apartment, this would have easily been a $250 unit, and would have sold almost instantly. Great score!

[Sean730]

Thanks again everyone! I adjusted the yoke ever so slightly and that did the trick. Got the picture level in two tries. So I suppose my next question is, if I am planning to use this set on occasion, should I go forward and replace any caps or electrolytics or leave it alone since it seems to be working fine?

[maxhifi]

"On occasion" I personally would leave it alone until something actually needs to be fixed, maybe buy a Manual for the tv and study it and buy a book about how tvs work and read it before jumping in. I use an older tube chassis CTC-38 with all original electrolytic capacitors daily without any issues. I am going to change them eventually, but for now it works just fine.

That's what I pretty much figured. I only plan to watch it for an hour or two every couple nights or so. Thanks to all again for the help!

Where is your sense of adventure? I've been adjusting them with the set on, on tube sets where there is higher voltage, and using a mirror to get it perfect for years....I even got a good shock once from not watching what I was grabbing and it has not perturbed me in the least.

What I tell someone to do, and how I do it myself don't always intersect... I think it's a bad idea to advise someone new to the field to poke around inside a tv that is turned on, when they aren't fully aware of the risks.

[Sean730]

Believe me, I understand there is a lot of voltage surging around in those various components and I will not be prodding around with it live, at least until I'm a little more comfortable. I've messed around with other electrics and electronics, audio amplifiers and such but not a TV. I'm going to do my homework first. And I think I'll be on here a lot more in the future....

I have the same set--in my house garage. It was a "shopping find" in 2009 in Monroe.

It worked the last time I tried, has a good tube but not a SPECK of color !! I have not messed with it in a few years.

up here right now in Hilliard. my ctc-7 is in the auction for the morning. THIS year--I WILL be there, and not in the hospital down the road!! (Lord willing !!) , on my laptop in the motel, getting ready for bed.
