Start with the obvious. Is your TV plugged in? If it is on a power strip, does the strip need reset? If all is normal there, then unplug the set and take the back off. Check your fuse to see if it is blown.
SOURCE: Magnavox 50" plasma Won't Power on/Shut's off/Blinking red LED
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!!

I had the Same issue. on a 50PF9431D/37 set. Many Plasma Set's use a LJ44-00118A PS-505-PH Power supply from Samsung. Known to have this common problem. If you can, or have a friend that can Solder components?. Unplug your set remove the back panel & locate your power supply. It will be the PCB in the center of the set just above the Video/Audio connections. http://www.shopjimmy.com/power-supply-unit-lj44-00118a-from-philips-50mf231d-40.htm. Is a Link to a photo of the PCB. Make a note of the locations of all cable connections then unplug them all. Un-install PCB, Check all Fuse first. I believe their is 5 or 6 of them on the PCB. Then replace the two 3300uf 10v 105C Radial capacitors at C8060 & C8059. Look to see if the Caps are deformed and or split at the top. The location of the caps are in the Lower bottom edge of the PCB. A local shop may Carrie them if not, digi-key has them. Part # http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=493-1754-ND. Total cost was $7 with S/H.

Unplug and replug it...it should work eventually.
I have the same problem with my 32".
But it eventually goes on when i try it a couple of times (the number of times is completely random...sometimes none, and sometimes like, 3).

PLEASE NOTE IF YOU HAVE NO EXPERIENCE IN TV REPAIR SEEK OUT LOCAL TECHNITION OTHER WISE CHACK THESE THINGS BELOW.
