Magnavox 40ME313VF turns on then back off. Power light blinks 5 times
I have a 40 inch Magnavox 40ME313V/F7 tv. When I plug it in the red led light comes on. Then when I press the power button the led will blink 5 times and power on for a few seconds, It does show the Magnavox logo then I hear a static sounding noise from the speakers, and it turns off. with the led light still on solid. When I press the power button again the led will turn off, after pressing the power button a few more time (5-6 times) it will turn back on solid. Then I can hit the power button again and the led will blink 5 times and turn on for a few seconds and show the Mganavox logo again and I hear the same sound and it turns off again. This can be repeated many times over and over.
I have looked for anything obvious on the boards such as burn spots blown caps, ect. can not see anything wrong. I disconnected the t-con board and same thing happens with the exception of the logo of course, the back lights do turn on. Below are some pictures of the boards.
Right now I am thinking it is the main board, anyone have any other ideas on with it might be?
