Good morning I have a 47-inch LG mid LED. ML7600 screen

MODEL LG 47 inches.mod.ML 7600 the screen turns black at times but the audio is heard. I disassemble it and it has two LED bars next to each other. I turn it on and they all work correctly and after half an hour they turn off. What could be the problem? I understand that if all the LEDs turn on the problem is elsewhere?

In Mercadolibre they sell them, also the loose LEDs, but that should be done by a professional. If not, they burn again.

Well I will find out. I wanted to make sure if the fault was in the led bar. When I saw that everyone turned on I thought it was another problem. But comments say that the problem is in the bar beyond that they all turn on

The problem is in some or some LEDs with low performance .... they walk for a while .... it is common in those rectangular LEDs .... it is best to change the complete strips .... greetings.

It happened to me with some lg that have come to me with that fault ... with those LED strips ... they walk for a while and the lighting is cut off ... they are doing well for a while and the LEDs fail ... or the TV detects the low performance and cuts the voltage of the LEDs .... it is solved by changing the strips.

You must measure voltage on each LED, with all the strips on. You must measure all the same, any voltage difference, that LED is bad. greetings
