Check your power supply board and resolder the pcb, check the switching diodes and zeners.

You need to check the horizontal drive transistor. This circuit provides the high voltage and other voltages needed for the television.

you should of recived a 0.01ohm resistor it is wite and sayes sony on it.
its a flame proof resistor that needs to be the very same
look for it on the pcb test it its probly open right.
ask them to send you the right part.

There should be circuit designations printed on the PC board. Without those, there are too many possibilities to give you anything useful. Can you provide those please?
Thanks,
Dan
