good I have a daewood TV that turns on, it is heard but it is not seen, the image is very dark, since I was doing some tests to see and approaching with an external light and even the daylight I managed to see the image but very dark, as If it were problems of the led lamps, 4 months ago I sent it to repair for the same problem, and before doing so disassemble the TV and mark mostly components and cards and some screws in order to verify any theft or change of parts, all well since the marked and photographed pieces were there .. My question is what may be affecting? since at the time of removing it from the workshop after 5 days the same problem happened and I saw it take it and the next day I was delivered ready, today the same thing happens, turn on but do not see, reviewing everything I do not see that they have done I don't want to take it back again because I don't have to pay for the repair and well I want to find out what it can be, I'm not a technical technician but I have some notion of electronics, How can I try the famous led lamps and also put power to verify that they work well. and rule out those damaged LEDs. and well that part would be then go to the card that feeds them greetings from Venezuela

If as the colleague says you have to disassemble the TV and get to the LED strips to see what they did

not there I did not come to disassemble it so just remove the cover to verify if there was any diode, exploded condenser and verify the components that you mark before taking it to the workshop .... hahahaha

Listen friend, you have to take apart the TV and check those who walk and those who do not walk, always ask the same thing. I do not understand you. Value the answers. Greetings

And if I change the LEDs or some LED strips you will not see it since they are behind the panel. Maybe the repair is not well done. Greetings

And sometimes the same owners of the TV, with the remote. They carry 100% backlight and burn. There are many causes.

Well in my case, this is how it comes from the factory ... I don't move much parameters.

That is why the repair technician must take precautions so that the repair lasts. There are many secrets in these cases.

I only last 4 months ... that's why my doubt will be the LEDs or some component that does not reach the full voltage of the LEDs

Responder

how to test the LEDs to verify that they are good and do not tell me that they are all burned for example

You have to disassemble the TV and take out the panel, to reach the LEDs, if it is not technical it is not convenient to do so. The panel is broken very easily.

no I will not disassemble .. with the cable that goes into the screen can you test with continuity or some voltage?

There is a LED tester in the forum, if the weapon can prove it, but if there is one burned or else they will not light from the outside.

Responder

of the small card that is seen in the photo goes a cable I do not know if that is who feeds the LEDs. That's why I have the doubt. if the LEDs could be tested in any way without taking apart the TV

it is not convenient for him to reach out, take him to an experienced technician and guarantee him at work. I leave him, here is 1 in the morning.
