I changed the Transformer and also the Transister recommended to change when the transformer went out. Now the tv powers on. I can feel the static in the screen when it comes on, but there is still no picture or sound. It stays on for about a minute with flashing red power light. Then turns off by itself making a static noise right before. Did I do something wrong when installing something? Or is there another part that might need to be replaced? Thanks in advance.

The problem is on the line transformer, this is a big transformer with a big cable going to your tube. what is happening is that, this transformer is over driving due to high power. Take your tv to be repaired by tech who is going to checking around the same transformer for a resistor or a capacitor ( electrolitic capacitors ) which has changed values. The change is causing high current to flow into your transforner. Thanks for asking fixya for held.
When the HVT goes out, it will take the HORZ output, in short, you will hear a high pitch noise for a sec, when pluged in. As to your question, Its not a hard repair, however its not what I would call a begainer repair. This is what make the high voltage (about 32,000 volts) for you set to work. If you DO try it, becareful. And don't forget to change Horz output p# 274762. After changing the parts, unit will not run for more then 10 seconds. You have to use a volt meter and set the G2 for 290v, with no signal and blue screen. + or - 5 volts will cause unit to shut off.
with your new flyback transformer ther should have had a resistor and cap in the kit.if you look at the fly back from the rear ,on the right side very close to the transformer.and on the other side 3 resistors one has changed value about 38k-ohm.
