The above fix, listed by Tom saved us!! We did as instructed and took off the back of our 50 inch Magnavox plasma tv. We were not sure what we were looking for so we googled capacitator (image) & there was a photo of a fried capacitator! Sure enough we noticed ours were "fried", we took out the board and went to an electronic supply store, bought the 2 capacitators ($2.00 each!!) and then found someone who did tv repair to sauter the new capacitators onto the board. (It is important someone who know how to sauter and recognizes polarity do do this for you) All in all we fixed this following the above instructions for $34.00 and our time. For a month we were told to spend hundreds getting a new power board!
Kudos to you Tom & thanks so much!!

When you have the red light that blinks four times on the 50" Magnavox Plasma Model 50MF231D/37, you should look for the capacitors on the power board in the center of the of the TV. Look for two 3300uf, 10V, 105c capacitors that have a build up of pressure that has caused the top of the capacitor to look rounded instead of the flat top that will be on all of the other capacitors. Changing these two capacitors fixed the problem of the TV not coming on.
I had more trouble finding the capacitors than changing them. I could not find them locally so I went to an on-line electronics supply store where they were $1.65 each and $8.99 to ship.
