Thanks everybody! Hope you read my reply, because I do write long. Good luck!
This group is great. I'm always here reading every day, even though I don't post every day. Always great help.
Just to give an update. I just replaced every filter cap in the set, and three resistors in the vertical section. These TV's are annoying to work on. I've worked on a few B/W Tv's and its relativly easy to remove the chassis. This 66 Zenith requires removal of the VHF tuner, UHF tuner, disconnection of convergance cables and cables to the yoke. There is however, plenty of room under the chassis for new electrolytics(since I do not stuff the old cans)
After replacing the electro's and vert caps I was just about ready to install the chassis. Two power resistors on the top of the chassis looked a bit odd. I touched one of them, and it basically crumbled. I was quite upset! I had the TV in the middle of our bedroom, chassis out behind it and parts and stuff all over the floor. My girlfriend wasn't home yet to see the unexpected surprise awaiting. She was OK with it . . . . . man was I lucky!
I bought two new resistors to install this next morning. Got those in and fired up the TV using the lightbulbs in series trick to make sure my electrolytic replacments were ok and no accidental shorts happened. I've got three bulbs that I can turn on and off in paralell. a 60 watt, 100, and 200 watt bulbs. Tried lowest to highest and no short. Yay! Plugged it in direct and she was Ok.
Used my HV meter for the first time. Brightness and contrast to min, and I was 3 or 4 thousand volts short of 25Kv. Adjusted Ok. Next was my convergance. . . . . . . . .
I have a DVD of test patterns that I used for convergance. I spent quite awhile going over and over the alignements. Not quite perfect. Some of the adjustments are on the full range just to get it "ok". I know in the future I will have to replace the rectifier and capacitors that are on the convergance board itself. But better than it ever was before.
My degaussing system is cooked. Something on top of the CRT looks like a ceramic cap broke in two, and something that looks like a super big ceriamic cap right next to it looks a little special . . . . I figure its the thermister and resitor. Am I correct? Where the heck do I find these thinggys to replace?
My old filter caps were ok. I didn't need to have them replaced. Keep in mind this is a 66 Zenith 24NC31Z that has been used daily for 3 years. But now that they are replaced I have a weight thats removed from my chest. You just never know when it will or would have failed. Or what would have happened if it did! I was super paranoid of installing the electrolyics for shorts and improper installation. I did a very thourough check of my work before firing up the set. Always double check your work.
I'll take some photos of the set in operation. I know everyone always enjoys photos. My avatar photo is of LOTR's 2 years ago. Its in 16:9 so thats why there are black bars top and bottom.
Happy Holidays everyone!
