Hello friends of this forum, I am writing to ask for your help I am repairing this 32 led tv has only audio but the dark screen with a flashlight I focus on the screen and you can barely see the images. The tests I am doing are medi voltages which They go to the main card are correct but those that feed the LEDs have a non-stable voltage measures 194, 200, 210, 220 and it returns to 194V and so it has no stability, well I do not have to be more tests to rule out if the led are fine but I have doubts with the source .... I hope your advice and sorry for the inconvenience God bless me

I understand there is a problem when I turn the TV around I hear some noises like they roll something inside the screen it's like if they were loose speakers

the diffusers of led are loose that happens in some occasions by heat in the led

Hello Jesus, I have read your problem and everything indicates that you have to make a discard of LEDs on the strips, there must be several LEDs burned, in addition some of the diffuser buttons that bring each LED must have been detached and that is why it sounds because it they have fallen, that sticks with a suitable glue that indicates to you, if you have never removed panels you can see some video tutorial on YouTube, the only thing I tell you do not remove it if you are not sure you can do it because you can break it, Good thing about your TV is that the screen is not very large and is quite maneuverable.
