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.

At this point, I would think of replacing the IR Sensor. We have found that most of the time that is the cause, of your TV turning on the shuts off--Go into the back of your TV and carefully clean the IR Sensor flex cable-- and see if that will get your TV to come on---If not just replace it--Also check Power Board for bulged caps, but I don't think you will find any--

Update (03/07/2019)

All right I just spent the better part of the day digging and searching for you and bugging people i know that know people to get this info straight from one of the lead Magnovox techs in Japan..

here is what he told me..

Although Magnavox has no error codes-5 red blinks is related to the power board-Pop is related to the Power board-

Getting to screen logo is related to Main Board, but can be caused by a voltage supply problem, to the Main Board coming from the Power Board itself-

We have been fixing 5 red blinks with a Power Board replacement-

he also said in rare cases that after the power board is replaced that the Magnavox 40ME313V/F7 A3AP1UH Main Board IC3006 EEPROM  might also need to be replaced..

I hope this helps..

p.s. your model number was not in the correct format ans very difficult to locate any info at first because of this..

40me313v/f7 and then there are some variations to this with a number or letters following behind the model number..

There are no bulged caps anywhere, I will be getting back with the customer and seeing about ordering the IR Sensor.
