Re: Samsung 40F5500 red light blinking

Coming with updates Moreno83......you were right it was blinking i did use a hair dryer and after 30 40 seconds it did turned on by itself and works so that means is a power board problem........it means that is an imperfection on the board or is there any component that is bad like a bad cap that you can not see.do i have to heatgun the board??? thank you

Re: Samsung 40F5500 red light blinking

But is not turning on the TV even if i press the power button red light still blinking.I was thinking that it is possible to be backlight only if is turning on and you hear a sound or something but mine is alway blinking.I i disconnect the board from icon you can see though the hole how is blinking the backlight
