This set turns on and off in split of sec.. you can see the logo Emerson in the screen in a sec then goes off...when I it power it blinks first and then turn on on the second and goes off.....I saw other post and said that caps were bad at c1006 c1007 I change them and no luck...I got my 3.3v in power supply....

I suspect a faulty LED backlight issue
To check you will have to dismantle the LCD screen -

But disconnecting the led from the power supply it should be on with out the led connected. At least should be audio on the main board, with a flash light I try if there's something of video but theres none.....I think it might be main board problem..the power supply what I know is that if you have your standby voltage at 3.3v or 5v your power is good....and the problem is mainboard. Well that's what I know.....any opinions out there, am I right????Comment

Re: Emerson--lf320em4f turn on & off in split sec
The problem was the leds inside they were short-burn at the look they didn't seem like it,but what I did is to make a rail of 18 ligth led. Why I did this??? to test the power supply if it working good and for that reason to be sure was the led or not...in this set of tv it only has a one rail of led strip which consist of 18 led ligths. So what I did from other scrap sets I took the strips to add up to 18 leds. I used rails of leds of 4 leds on each and of 5led and try to make it fit. But basically that's your problem on this set..Comment
