Good night here in Venezuela. The TV is heard but not seen, check the voltages on the connector that led to the LED strips and indicates approximately 58 V. Check the THREE LED STRIPS you use (OF 8 LEDS EACH ONE) and the one in the center has 4 damaged LEDs. The strips indicate that the LEDs are 3.4 to 3.6 volts. It can be used with the 2 LED strips that are good. Here in Venezuela it is difficult to get both the strips and the LEDs. I appreciate your collaboration in advance

NEGATIVE, the voltage is for all the exact LEDs, and if you bridge by the time you burn the others. Where in Venezuela are you from?

Hello Friend. You can not use with those 2 LED strips that have good because the image would come out with shadows, therefore you have to place that 4 LED, which has burned. Cheers

Hi. I support what was said by colleagues. but answering your question to my knowledge if you can use only two strips. I know it sounds contradictory. Think a little bit . If you remove the strip you will have less lighting as a result it will look dark. In the area that is missing the strip. Assuming you use two strips You will have to modify the supply voltage to the LEDs. Otherwise you will burn more led. because if the LEDs are 3v and multiply by 24 LEDs, it will give you an approximate estimate of 72v. And if you use 2 strips or 16 LEDs they will be powered by 72v. That is 72v ÷ 16 = 4.5v. 1.5 v of more. And that's why they are going to burn. You must notify the customer of the citation as you say they are not achieved. As a technician I suppose that maybe you have another TV to get LEDs of the same characteristics. And put the tv. And of course also communicate to the client the citations. And you should also reduce the voltage that the LEDs feed a little. So last longer. If you don't have a colleague there, he asks you where you are from. Maybe it tells you where to get. Or he makes it easy for you.
