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.
