SEMP	48L2400	Turns on with logo and turns off backlight	LED lights up, but it's defective	I quickly tested all the LEDs and found only one open, all the others lit up. When I finished the replace, I turned it on and the defect still persisted, but I noticed that tsound was a light flickering (trembling), I placed cardboard covering the bars so that I left only one of the bars exposed, I tested them all and discovered the bar that was shaking the lights. I short-circuited it with a wire isolating the LED from the LED and I found an LED that caused the defect and the damn thing lit up, strange, but it lit up and with the direct test I hadn't noticed it because I only touched 6 volts, it lit up quickly and I went on to the next test. A tip to keep an eye on, you waste a lot of time researching these cocks. hug! alex nardi	Tecnardi
