Hello Cristian. Thanks for your comment, it happens that the TV has already expired its 60-day warranty on the display change.
The TV was repaired far from where I live, so I wanted to know how to enter the service mode, so solve it myself, I clarify that I dedicate myself to the electronic wing, but I do not have that information to do it, thanks for collaborating, a hug.
Hi Goegrow. I appreciate your cooperation, I commented that I tried your suggestion, but I can not enter with that command, search on the Internet about that brand and model, but find nothing about it, with commands from other brands and nothing. The truth is that for time, distance and the warranty has expired, I do not take it where the display change was made, if there is any other method, I would appreciate letting you know, regards.
Hi everyone. I want to tell you that I have already managed to solve it, I provide the sequence for those who may need it.
The sequence is: Menu 1-1-4-7 In the menu that appears, look for a mirror and turn it off, the image will be normal again, then menu again, turn off the TV and voila! Turning on the TV again will look good.
I want to thank the people who contributed their comments, greetings and I will close the subject.
Closed topic. Thanks to: cristian78, gabriel rodriguez moscoso, geogrow for contributing his help, I will give value to all three, blessings and keep it up.
