TV had a smell and then went out. When we turn it on it flashes green on the power button. What can be wrong? It is a Philips Magnavox 42MF521D/37 Please help.
Thanks
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.

Hi,
replace a transistor in the power supply and a diode that has shorted out near this transistor,this transistor is located near other in the same heat sink,and check the tall caps for swollen top,thanks everyone!!!
U have a dead power supply board,burn componnents parts on the power supply board.Replaced the power supply board,u will get ur power back as normal function as before.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.
