    I will check for voltage. I dont understand this part: tried first to disconnect the supply connector going to the inverter board for back light just to ensure if their is no shorted component here. and then turn the power on again if the light stay . Please elaborate.

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!!

tried first to disconnect the supply connector going to the inverter board for back light just to ensure if their is no shorted component here. and then turn the power on again if the light stay then the inverter board was the cause why won't power on. by the way did you make a voltage checking at the power supply board does it have correct output voltages 5v,12-16v and the 24v.

I have a 50 inch Samsung Smart TV UN50EH5300 that went dead...so I replaced the voltage supply board and it came on sound but no picture.


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.
