Tilted picture? also, white outlines around images?
A while ago I got a 1985 Sears (electrical components made by Sanyo) console TV for free out of the classifieds. This TV is in immaculate condition; the cabinet is perfect, and the picture quality is phenominal. But there is one problem. The picture is slightly tilted. It's not noticeable when watching a show with a normal picture size, but when a widescreen show comes on, it's very obvious.
So are there any ways to fix the image? Because it's driving me nuts. Also, while I'm posting this here, I also have a 1983 13" RCA XL-100 TV that has a wierd shadow effect on the image. Everything seems to have a grayish white outline to it, and the picture is obscenely sharp. i tried adjusting the tuning, focus, etc. but that has no effect. What causes this? Is there a way to fix it or am I to put up with it? Even for being over 20 years old, these things are great otherwise. I'd like to see some POS plasma last that long.

The deflection yoke is probably out of position on the Sears. The yoke is the large copper wound device that's fitted on the CRT neck. To reposition the yoke, loosen the clampscrew that holds the yoke to the CRT neck and very carefully rotate the yoke left or right until the picture is straight. It should only take a very small amount of rotation. Do not move the yoke backward or forward, as this may mess up the purity and convergence. Also be aware that there is 25,000 volts on the CRT anode and there is some nasty voltage on the yoke terminals; so, use caution. Once the picture is straight, hold the yoke in place and tighten the clampscrew. Those old Sanyo built Sears sets generally hold up well and produce a good picture. I think you'll be pleased once everything is adjusted properly.

My aunt has a 1985 19" tabletop Sears (Sanyo) which looks absolutely great. Colors, focus, tuning are all excellent. They do hold up well. It worked 100% as found on the sidewalk. Cleaned it up and gave it away.
Hmm, seems like wilkes is banned. Maybe it was his drunk posting in the tube audio forum.

Well, I chickened out and decided that the picture isn't really that bad. LOL I didn't want to be screwing around in there especially since I have limited experience with this sort of thing.
But while I was in there, I adjusted the focus, and now the picture on this thing is razor sharp.

A while back I found a little 13" color made by Sanyo that also had a tilted picture. I wonder if it's a common flaw with sanyos.

If it's a common flaw, blame the crappy wedges and yoke screw they used.
