LG TV turns on and off continuously
Check the LED diode panel should have a short or open diodes Claro that first discard dry or inflated capacitors in the power line. I also recommend that before doing what I say, turn off the power of the panel, place an antenna and turn it on if it starts and has audio for sure the problem is in the LED strips.
If you have damaged LEDs, just change them, you must be very careful with the large panel and if you don't know how to handle it, you can break it ... regards.
Hi. I support what was said by colleague Francisco. More for what was said in your question.
to find diodes in the panel with problems, is it repaired? Thank you
Must have led tester. Measure consumption.
And know how to change them.
Have the tools for the job.
Ok, I am from the old school of TV tubes, I have not managed to integrate myself to this new technology, I am sure to check but perhaps it does not advance, on the other hand, here you do not get any spare parts of this, just by ML some full screen.
Thanks for the help.
Gentlemen, I put on and disarmed everything and reached the LEDs, I didn't have to do much to tell me, practically the affected LED strip is burned, he asks; does anyone know what led this LG 47LB 6500 TV has? I have the data that appears there, tomorrow I go out to buy but I do not know what voltage they are said on the strip: AG-D1-94v-0 1441 LG INNOTEX DRT 3.0 47 "_A Type Rev02_140218 thanks for the help.
I already gave him part of a tool so he deduces how many LEDs are if he has little experience. But he didn't care.
Now he doesn't know the characteristics of the LEDs.
Take annotated or burned strip to a store and they will sell it to you. See if you have the same characteristics.
Now how do you know if you have no more burned?
Luck in the repair
Mr. Luis, don't be offended. I understand that your tool gives me voltage to continuously turn on the LEDs, in this case my LED was melted and burned part of the plate, I measured the others and they were all good, take the led strip plate and they sold me a strip of 5 led, install it, assemble everything and came out running, after cleaning and lifting the short the source stopped protecting and started well. Thanks to all for the help.
All good. I'm glad it will repair.
To make it clearer. With that circuit you will not only turn on the LEDs. But you can also measure the consumption either individually or the strip.
If it measures 15v. It divides it into 5 LEDs and knows that the LEDs are 3v. I would just have to see how many watts they are.
