I have a service manual for the Sylvania/Funai model 6427TD/SST4273,
not C6427TD. Will that do?


Maybe, maybe not.

The information I need is easy to locate, maybe you can check it for me: I
need to confirm the voltage output from the supply that power the
flyback. The TV set is working, but since the picture sizes are too large, I
wish to make sure the supply output is not too high too. And second, I need
to know if they have hidden menu to adjust picture sizes (vert & horz) and
how to access them.

The original problem of the TV set was the vertical output IC that was blow
up, it as been replace, the TV work, but the picture is quite large. So I
suspect that the supply may be a bit high causing the IC to fail and the
picture been too large. I may be wrong, the picture may have always been
that way too, I did not saw it before it came for repair.
