after recapping check to see if the raster is filling out the screen. You have to be careful with all the whack formats that are out there now. You need to make sure you have a good 4:3 format. If the raster is filling out the screen, and then you get bars on the blanking bars on the top and bottom or sides, then its prob the video format. Post of some pics or better video of your progress.

Went ahead and recorded a video addressing my current issue with the set. https://www.youtube.com/watch?v=SSkjb6RyOfs

Looks like it's losing horz sync.. I would check to see what the current is at that cathode of the horz output tube.. Should be around 200ma range... Something I should have done before smoking the fly in my Magnavox set..

Checked everything. All readings normal and I am pretty sure I fixed it. Now the question is how do I get the colors right? And the purity and convergence the best I can WITHOUT a pattern generator.

Purity you can do without a pattern generator.. Lower both green and blue drives on a station that is not coming in (Just Fuzz), and then once you have the yoke adjusted, you'll have to switch to a TV program to level all three drives.. If you can find a station that is letter box, you can go by the color of the bars on the top/bottom to level the grey scale.. I think there is a place to where you can download a DVD of the patterns... Convergence you'll need the patterns and using the cross hatch pattern is the best for that, or at least for me it is..

To perform purity on a set, you'll need to start with red and also degauss the tube before you start... Pull the yoke back and adjust the purity rings until you get the red blotch in the middle of the screen then push the yoke forward again and see if red fills the screen without any fading...
Shango has videos that are helpful https://www.youtube.com/watch?v=QNtsTKVPO7I https://www.youtube.com/watch?v=1AWG61TAIHg

at about 7:00 it talks about setting up purity. Before doing anything else I recommend you look on ebay for an RCA color service manual by carl babcoke. http://www.ebay.ca/itm/RCA-COLOR-TV-...3D311360906136 oh and start looking for a degaussing coil. |

there are height and lin adjustments as well as a vert centering adj. All of those are used in setting up the correct sweep.
The book I mentioned covers this. There is a correct process in setting up a set, needs to be done in order. a quick summary goes like this set height and lin using test pattern. degauss crt purity setup center converge with dots from test pattern dynamic converge with grid from test pattern |
