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.
