Hello friends of the forum, this time with an LCD TV that came to my workshop with the dim screen on one side and the other with normal brightness when uncovering it check source with normal voltages reaching the stable 12v and 5v meinboar card uncovering to verify the leds I find half of the leds reflecting the other half well zero, my question is; Do these LEDs change half? or all the strip, and how much is the value of the voltalje of the same and how the strips are changed because it is the first time that I have aunts like these who go in the bottom and are several side by side. I forgot the model of the LCD TV ADMIRAL model EF 3912 from now I thank your contribution

Hi Santiago, thank you for your input, my question is if these LED strips are achieved? And, how much volage do they work with? As I said is the first time I have an LCD TV with this LED strip, they stick with some special glue.

These LEDs are quite strong I imagine they must be 12v or 24v and if I know that they are in series one that does not cut the circuit of other LEDs, how do I test one by one? Do I test them with 12 o24v or less voltage?

Hi Santiago, I want to tell you to solve the fault when I take out the strip of LEDs that are 52 leds in the part that enters the signal not towards contact it was detached I guess it took off by the heat and likewise check the other side, the other 52 leds were at point of detachment, the strips are in good condition I thank you for your contribution you have solved, a hug
