on naturally its all snow but not shuting down.it also blinks twice on
front of set which means short in current protection cir.so sony code book

A Sony that shuts down when cable signal applied is almost always due
to the horizontal frequency (free-run) being too far off. Yes, this
will cause an overcurrent protect shutdown. Main B+ regulation being
too high or low will also cause the horizontal frequency to be off.

Double check the free-run horizontal frequency (no signal applied) to
see if it is within specification.
