Good afternoon people . I want to ask you a question to see if someone gives me a hand. I have a 32 inch lg tv. It began to lose brightness from the right to lose the image completely (it has sound and everything goes except there is no brightness, it is more I do well it looks dark image) I read a lot and I know that it can be the led strips (I have 3 inside from the tv) or the source board. The problem is that I am very fair and I really have bad experiences with technicians who want to charge me fortunes and I really don't know how to test or know if it is the source or the strips. Can you give me some information or recommend someone in Buenos Aires, who doesn't kill me? Jaaj do not know how ugly it is to have my 2 children on vacation and without TV .. a data . I was about to buy the source plate in ml and change it but the question I have is that it makes noise one of the coils (I think they are yellow squares coils) and when I unplug the cable that feed the LEDs it stops making noise .. someone knows which will it be the problem? I do not want to buy something that is not .. I give myself tomorrow with electronics since I did 3 years of technical but more than a tester I do not have to test. I appreciate the help .. Hugs. Nico

It can be both. The best thing to say is that they are the LEDs, in order to test them you need to disassemble the entire lcd panel, with how delicate it is. Like your cables, patience. To test the LEDs use the tester in the diode position and look one by one in the absence of another tool that is good and valid. The bad look one by one. if you take off the reflectors do not worry you hit them again in the same position. once ruled out that they are not the LEDs you can already say that it is the source and focus on testing this to repair it or buy one but not before. As I said before, the safest thing is that they are the LEDs. They usually have several in poor condition or even short.

Hi Nicolás, I think you have to take a trained technician in LED and LCD, do not spend on plates, sure it is an open or short LED, and if it did not turn on one is because it must be 6v and 10k ohm analog tester turns on just .... and if you do not work to repair led you have to invest in specific tools to repair led. I had to train and burn several LEDs to learn and a lot, a lot of reading.
