Yup a Sanyo. These usually had Sylvania CRT's EIA 312
VERY good sets as a rule.
If it uses any IC sockets watch for very int problems.
Sounds like you have HV but no raster. Look first
at the G-2 on the FBT then resistors on the CRT brd in the G-2
if any.
BTW the big white tag with the long number starting
564. ####### is the real model. 4 digit sears numbers
are near useless.
