Hello and merry Christmas, I got a lg 32lc5dc screen that bought it in a hotel and came in hotel mode obviously, I already deleted in module that is between the cable entry and the tuner and so the auto programming icon appeared in the menu , I did the self-programmed channels and everything was going well until I disconnect the TV from the network and to my surprise the channels are preserved but it changes the signal and it is still heard well, the channel indicators vol. menu etc if they look and the screen completely black ,,, someone can give me a tip to do, PD I have the service control Thanks in advance for your input. greetings from Mexico
