Most likely the flyback assembly, and or the horizontal output transistor failed. There is also a possiblity of some other faults that are putting the power supply in to the protect mode.

If there is a scan failure, it is possible that there is also some damage in the power supply.

The set will have to be serviced by a TV service tech.
