Hello! If you can set the voltage and current they need, they have to be electrically and physically similar so that there is no greater consumption of one over the other and physically so that it does not make light points on the screen. The LCD is exactly the same as the LEDs. The only difference is the shape of the back lighting, which in the case of the LCD is formed by fluorescent-like tubes, and the others are illuminated with LEDs. But both are LCD.
Well Carlos the TV I have has
Three LED strips on the sheet
I have to put three LED strips
Common in the same position
Friend Carlos who advise me
Les 12v or 24v
That depends on the source you have in the lcd, you should see if the brightness varies with the different tensions they handle.
In Mercadolibre they sell the 3 strips at a good price. The original strips are always better, the LEDs do not burn because yes, that always happens when the driver source of LEDs fails. So first, you have to repair the source of LEDs and then change the strip, if not history repeats itself again.
