[TechAssist] Sony KV-27EXR20, Chassis SCC-D50E, Shuts off

This set plays for variable lengths of time, then seems to "pulse" in=20
from the sides, finally shutting off. I say shut off because you can =
hear
the relay click off, and then you can turn it back on.  One of our crew
replaced the regulator with the correct part, and the power board ("G?") =
has
been completely resoldered (there were some bad connections) as has a =
large
part of the main board in the power and horizontal sections.

The last time I saw it go off with my own eyes, it seemed as though I =
could
see the horizontal deflection collapse just before the shut off.

I do have the schematic, I wonder is anyone else has solved one like =
this?

Thanks,
