A lot has gone on since my last post. I kind of wish I chronicled it a little better.
My iIF Board problems ended up being a bad solder joint. I could only find 5% carbon composition resistors through Radio Days and it took them a week to ship. So I got impatient and put the board back together. While I was at it I went through the board and reflowed every single solder joint just to see what would happen. I put it back together and all the voltages were dead on.
I set the TV up and my horizontal was going crazy. I asked advice from someone and he told me to adjust the horizontal coil and the horizontal wave form coil. Doing this got me a decent picture, but the top of the screen was twitchy. He told me that's probably the TV having trouble syncing. So I recapped the sync separator board, and at the same time I had lost audio completely so I recapped the audio board. I actually had open caps in both boards. I have to go through my notes to tell you guys which ones but it was very interesting.
At that point I turn the TV on and the horizontal was off again so I readjusted the whole horizontal. And had a pretty decent picture. I went to bed last night, the next morning I turned the TV on and had a complete loss of horizontal adjustment again, this time I could adjust it with the knob on the Tv, I added a picture of this down below. The picture is what the TV looks like every time you turn it on after it's sat overnight. If you turn it on and off while it's warm the picture comes back like nothing's wrong, and it doesn't lose horizontal sync the whole time the TV is on. But I have to set the horizontal everytime I turn the TV on.
The next thing is I tried to set vertical linearity for about 2 hours. Using the B&K 1077 slide I cannot get that circle around no matter what I do. The only way is to shrink the vertical so that there's an inch missing on top and bottom, otherwise it looks like an egg. I can't make the circle round is there a trick to this?
The last thing is the picture isn't very sharp and I'm getting these lines going left to right on the screen they almost look like the digital fake scan lines they add on YouTube videos and things like that to try to make them look old. Is there a way to fix that?
I made 3 youtube clips of the TV playing a DVD, and doing crosshatch. I also took some pictures.
Here's the B&K doing cross Hatch

Here's the same movie and I'm trying to make the picture sharper playing with fine tuning and a few things
