LG 50UH5500

This is a repair of an 50 Inch led tv. The problem it was having it didn't have sound and the standby light was blinking 3 times. After opening the TV I checked the power supply and it looked ok After I checked the wires that go to the back of the TV. As you can see from the picture there are 3 white wires and 3 red wires. These wires are connected to 3 led strips at the back of the tv. 2 of the strips worked but the last one did not so I had to take the screen off and repair the back-light. You can view my other repair videos for more details on how to do that.
