Power went out, tv won't come on
If you are lucky, it's only a blown fuse, but with a blinking light on the front, this is doubtful. I would pull the back cover anyway and check the fuse. If fuse is ok, then normally if you have no sound and no picture, you have a blown "horizontal output transistor". Look for the big wire (usually red) coming from the picture tube to the circuit board. The red wire goes to a large object on the circuit board called the "flyback" transformer". Usually very near this transformer you will find the h.o.t. (horizontal output transistor). It will normally be mounted on a silver piece of metal (a heat sink), about 2 or 3 inches square or possibly rectangular. The transistor has three pins coming out of it and is probably the largest transistor you will see that has only 3 pins. The upper portion of the transistor will be clamped (or screwed) into the metal heat sink. You have to desolder the h.o.t. and replace it with a new one. The h.o.t. usually costs only about $10.00. If the fuse and h.o.t. are good, then the "flyback" is probably bad and they run from $25 to $100. If the TV is worth only about $200, then replacing the flyback is not recommended, because there is no guarantee that this will solve the problem. Keever.
