If you have what I think you have, you'll likely find a shorted horizontal output transistor, two shorted switching transistors in the power supply (these may actually be two transistors in the same package since this is a 2000 model), and an open low ohms fusible resistor in the power supply. It will probably be white in color and be located close to the heatsink that the shorted transistors will be attached to. The most likely reason for these parts failures is loose connections in the horizontal deflection circuit, especially the horizontal driver transformer. It's best just to resolder everything in the horizontal output and drive area. Unfortunately, other things, like a bad flyback, can also cause the parts to blow. The only way to check the flyback is with special test equipment. If you don't have access to such equipment, you'll have to take a chance with the parts and resoldering and hope it does the job. I had a 36" Sony from 2000 that smoked new parts despite my efforts to prevent that. I decided to junk the set rather than blow money on a flyback and the other new parts just to have the whole thing blow up in my face.

BTW, don't use cheap chinese knock off parts in this application. Many places sell a cheap parts kit for something like $9.99. I would not recommend going that route. It would be best to spend a little more on the original Sony parts. Many of those knock off parts will either instantly blow up or fail within a short period.
