RCA Victor portable TV from the 1950s

Just install the yoke dirty side up...even if you cleaned it there are probably still some nooks and crannies with dust to indicate which end was up...

Well the way the yoke is wired in there's only one direction it can go but for some reason I can't seem to get the yoke oriented correctly so that the picture isn't slightly tilted to right or left or completely sideways.

If you are getting close, you should be able to zero in with tiny adjustments to the rotation. (?)

Well I think I got the rotation fairly close to where it should be for right now.

But the TV is still doing some funky stuff, I have a video I have made of what the TV is doing that I will post below.

The TV is flickering, bouncing up and down and the screen's height is still not right (and its not letterboxing either) and the top of the screen is stretched much more compared too the bottom of the screen.

Any ideas as to what could be wrong with the set?

Yup...put some kitchen grade rubber gloves on and rotate the yoke with the set on while watching the screen. That is the only way to get it exact without taking forever.

If you know where on the yoke it is and isn't safe to touch and have as much brass as I do you could do it bare handed...granted the yoke can bite more painfully than HV (ask me how I know) so gloves are the safer way to do it.

OK So I think I may need to either source a new picture tube for this TV or else get ahold of some paint to repaint the back of my picture tube because my picture tube's 'dag coating has failed on me, several large chunks of the 'dag coating on the back of my 17DSP4 has flaked off which is causing my picture tube's flickering problem you see in the video I uploaded onto youtube and posted a link to on here.

So does anyone on here have a 17DSP4 picture tube they would be willing to part with? I would hate to have to ditch the original picture tube from this TV as it still performs nicely (it still has lots of life in it and is still nice and bright).

But the only way I could save this picture tube is if I could source some of that paint some of you guys on here use to repaint the back of these picture tubes with, but I don't know what its called or where to get it from, or how to go about applying it without messing it up, as I've never used it before.

Help!
