Question about Televison & Video
Check the freewheeling capacitor connected to the collector of this switching output transistor for open. Check the serial resistor too.

After replacing the shorted Line driver Transistor, carefully removing and replacing the same CRT base circuit, resulted with the problem going away. I cannot say what really was the cause, but I suspect that there could have been some form of acing on the neck of the tube.

Be sure to use an ORIGINAL Sony transistor and be sure to resolder the pins of the small horizontal driver transformer and all parts connected to and around it, and your set should be fine.

I have not worked on your particular model. But, I have serviced many TV sets over the years. My answer will ge generic.
Check all the capacitors in the horizontal output stage and power supply areas for high ESR. All the caps that are out of spec must be changed.
The high voltage multiplier & flyback can also cause the fault you are having.
You have to consider that the DC voltages are not the only important spec that has to be met. There are also many power drive signals that work with reactive devices. If there is any defect in the critical areas there will be failures.

Once the power supply is restored the voltage feed to the processor and sub sections must be checked, for failure of any regulator or fusible resistors
