First place to look is to follow the power cord inside the set to the main fuse---look at that first. If you are not able to do that get a shop or tech to look for you.

SOURCE: TV went out.

This is neither the power supply.
Replacing a transistor will not solve the problem either.

The smoke comes - most of the time - from a Y sustain buffer board; Betleano above tells you one small thing that's needed to be done on the Y sustain board, but it is MOST CERTAINLY not the only thing that will need to be done.

At the very least you will need to replace a buffer board or you risk burning another transistor and possibly more.

There are two sane approaches to this: have the Y sustain board repaired and replace the two buffers; or replace all three (the Y sustain board and the two buffers) together.

While theoretically possible that your problem might be elsewhere, 99% of all 42'' plasma Magnavoxes that come to our shop have that problem.
