No Power on Sony TV

Again, you must be sure to use an original Sony horizontal output transistor and you must resolder the pins of the horizontal DRIVE transformer, not the flyback transformer. The horizontal drive transformer is the little transformer that is connected to the BASE of the horizontal output transistor, with 4 working pins. The flyback is the large transformer connected to the COLLECTOR of the horizontal output transistor, with many pins arranged in a circle. The little drive transformer has one or more large resistors near it and the little drive transistor. Be sure to solder all pins of that little transformer and ALL parts near and around it, and all parts between the little transformer and the output transistor, as well as all damper diodes, safety caps and yoke connector pins. If you have resoldered all of those and used original Sony parts and the set still fails, it is time to take it to a qualified tech familiar with Sony sets.
