Sergio thanks for answering, I was reading quite a bit on the link but I did not find someone who has this fault, most of them are reset, samsung logo appears but it is not my case I think, mine only flashes the LED for a few seconds, then stop and start again and so on and wanting to turn on with the control does not respond (I clarify the control works well), greetings
Hello Sergio!! After so many months with the TV standing there without touching, I decided to repair it, I bought a tv with a broken screen, a Samsung Smart 49 mod UN49K5300 is of Mexican origin, a colleague gave me a video where they make a plate change on these TVs I put the main and the source of the Smart from 49 to the UN40d5500 and it came out of luxury, the t-com is the original of 5500 and you just have to modify the backligth connection. The two positive ones to a cable and the two lands to the other one of the entrance to the back and ready, it is not necessary to modify anything, greetings
