Thanks everyone for the tips. I've made a little progress on the Predicta... All of the electrolytic capacitors have been changed. This was quite a challenge since the originals were multi-section can type caps and the replacements are Sprague Atoms. Terminal strips were attached to the chassis to mount the individual capacitors:
Powered up the set, and it seems that I have a worse picture than before.
The image near the top of the screen is still squashed... even worse than before. It is concentrated into a band that is about 2" high near the top. Also, the picture will not quit rolling. If I adjust the controls to stop the rolling, it will be OK until the scene changes, or a commercial comes on, etc. and then will start rolling again.
Here are some pics:
All of the original paper caps have been changed by a previous owner. They look similar to orange drops except they are purple in color.
Any ideas of where to start checking?
Thanks!
