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.
