Just fired up my parents' 1981 pfr100 and it runs better then I thaught. The source I am using is a DVD trought the video RCA jack. Just finished to adjusting it and still have two problems:

1 - picture has a shadow that leans to the left and jitters (looks like one of the two interlaced frames is ok but the second one just jitters to the left). When it warms up, the picture gradualy re aligns in an upward motion. Tends to stay a litle jiterry at the very top edge but not very noticable. How can I find the source and fix it? Is this going to get worst?

2 - Picture is off center by about 1 to 1.5 inches and the left portion of the image is out of frame. It has been like that from day one, remember noticing it many years ago and getting greef for for finding a defect on a new TV. Where can I adjust for it? it's not a mirror or screen problem, everything is well in line.

Allready tried the knobs on the large convergence board. Cant center image. Any one know what the following pots do? I've found 2 on the conv board labeled "keystone balance" and "voltage adj". Two more on the board at the back of each gun, and found a few more very hard to reach on either side of the board located under the front control panel, under the controls that have a secret cover on them Anyone knows what they can do... please jump in!

Thanx,
