It LOOKS like you have the orange-drop safety caps (on side of flyback) and if so....you should NOT need to worry about failure. I am not saying they NEVER fail--but I KNOW they are far more reliable than the tubular AR caps.

And what about the under chassis? Isn't there supose to be safety caps under there also?

Need a better pix of the right side--to tell for sure. ALL of the right side, near the HV area.

Hey thanks! And you know what? It works! I decided to plug it and see what kind of results I might have. To my suprise, it wasn't too hard to set it to get an acceptable image. But, hey it wouldn't be fun if it was 100% good... so here goes : 2 problems I can see right away.
A part of the screen is darker. When I watch a movie its not THAT noticable, but its fairly evident in the THX setup. Secondly, when I want to set up the convergence , it's like all the color are too strong and even if they are perfectly aligned, some colors are too "fat" and they come on top no mater what (see picture). |

What did you hit for the image back to normal?

When you do convergence turn the brightness & contrast
down so its not to bright. Be sure the focus is as good as it can be. Use dots not cross hatch if you have dots. Start with JUST the center using the 4 magnets. When center done follow the instructions for the rest. You will go back & forth till its done & the edges will NEVER be perfect. BTW its easier to lean over the set than use a mirror IF your arms are long enough........ The black blob is probably in the blanking circuit. I have seen something like it a few times but dont remember the brand or anything else. 73 Zeno |

Hey there Denis,
All it took to get rid of the 3/4 inch gap at the bottom of the screen was to play with the two controls for : vertical linearity and vertical centering. They are located behind the right speaker. I thought at first that it might have been a bad cap, but nope, only misajusted controls. |

As for the blob, is it a dangerous problem? Could something blow and damage something else along with it? Edit : Also I would like to know if all the dynamic convergence pot are suppose to turn smoothly...some do and some need a little convincing to turn. Could dirty pots affect the convergence (much like dirty volume pot can create some scratching and distortion?) Got this to clean the pots do you think it will do the job ? : http://www.mgchemicals.com/products/...-cleaner-401b/ . I know its desing exacly for that but just wanted to get opinion on that stuff before using it. thanks! Last edited by Dreamsbeard; 04-12-2015 at 12:22 PM. |

they are wirewounds and not meant to be moved a lot, so yes they are a little hard to turn. if they are not rusted then they are prob as good as they are going to be. they prob have dug into the wire having not been moved for decades, so prob have a spot where they will feel different.

Make sure to turn color down to non-existent before converging the screen. Sometimes sharp contrast transitions can create IF/video ringing that is of the right frequency to trigger the chroma decoder to generate a false artificial fringe around the bar.
