I need a manual
Philips has the FAQs and manuals for the 42MF52D/37 here: http://www.m4c.magnavox.com/cgi-bin/cpindex.pl?ctn=42MF521D/37&mid=Link_FAQs&scy=US&slg=AEN . The direct link to the User's guide is http://download.m4c.magnavox.com/files/4/42mf521d_37/42mf521d_37_dfu_aen.pdf . You will need Adobe Reader of a similar program to read the manual.
Is there a specific problem you are having with your set? (OTA or cable setup or another issue) Please add a comment if you would like additional support. Note: digital OTA signals are subject to a "cliff effect" if your tuner doesn't get enough data from the antenna. This will be determined by the tuner, the antenna location (indoor, outdoor, elevation), distance from the transmitter, and any splitters or other wiring problems. I've seen failed amplified splitters turn into filters that block the incoming signal from reaching the TV.

It is the low voltage power supply. I just had my set repaired and it had the same symptoms. My set is out of warranty. The repair cost is around $200.00.

The solution is the same I used for srjohnnichol, June 4, 2009. I promise you, this will correct your problem. Stop waiting an getter done!

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.

Is the TV's name Damien??
I think it's the main power supply. This happens far too often on new sets.
