I don't remember the numbers at the moment. The horizontal output transistor (HOT) will be a fairly large, black transistor w/ three terminals attached to a heatsink close to the flyback transformer. The flyback is the large device with the large red wire coming out of the top that connects to the top of the CRT via a suction cup.
The other transistors in the power supply will be on a heatsink on the smaller power supply board. Since your set is a 2000 model, I'm thinking that instead of two seperate transistors; there will be an IC with six terminals mounted on a heatsink. This IC is actually 2 transistors in one. The small white fusible resistor will be close to that heatsink on the power supply board.
I think I had around $30 in the parts that I had the displeasure of watching fry as soon as I hit the power button. The flyback would have been another $50 + $30 more dollars for new transistors, etc. I would have had over $100 in a set that might not have worked. And, I'm really not a fan of newer Sony's; so, making the decision to junk that TV was fairly easy.
Find out how the picture was before it went out. I've seen plenty of Sony's of this age with weak CRT's. The symptoms are poor color, color bleeding, poor focus, and a picture that flashes on and off. Sony's from this era have an AKB circuit to automatically adjust the bias for the CRT. When the CRT becomes too weak, the circuit can't compensate for the defective tube and the picture flashes. If you find out that the picture was poor before it went out, just go ahead and dump it.
