Good, I'm Patrick, my first question on the page, I always read interesting things about failures in general. I have a samsung un32f4000 led tv what happens is that it turns on it shows the samsung logo and after 2 seconds it makes a blink and it is as if the screen brightness went up. The screen does not remain black, but the graphic does not appear, nothing remains on the TV, when I press a button on the remote control the red LED on the TV flashes only. Disassemble the screen and the LED strips light all. I hope you can help me, thanks!

You must change the main, the same thing happened to me with a TV similar to yours, change the main and ready, the fault I had was that the logo appeared, then it was removed and did not show anything else lit the LED lamps but did not graph more. regards
