Good morning, this TV came to me and the front LED flashes red, first 6 times, I checked LED strips and one A and another B were damaged, I put others that work well original. Then, when testing, he turns on the backligth for a few moments, does not get to give any image in that short time of ignition and turns off again, the red LED flashing 5 times. The source is external 19.5v. The owner told me that, from what he told me, it was progressive, he would turn off only sometimes and then more often until he was protected, because of the issue of the LED strips for what I saw. What is wrong with that code? I did not find a reference for that model, I would appreciate that data. Thank you.
