Hello good, I explain my problem, it turns out that I bought a tv box since this TV does not have Smart or tdt and when connecting it I did not see the full screen, and investigating there I saw that it had a secret menu (062596 + info), with what I got to touch the geometry and try to see the full screen, the fact is that as I am very beast I think that the option to enlarge horizontally happens to me and I opened it so much that the television now turns on and endures at most 3 seconds, which does not give me time to get back to the menu and leave the geometry well, and I do not know what to do since it is 2 or 3 seconds and turns off, and so on, I have also tried to keep the TV volume keys tight and give power but does nothing the most I see sometimes is that the blue LED of the TV makes a sequence of 3 blinks stops and then 13 blinks. I am desperate for entanglement I am not able to tear it away, I just wanted to connect a tv box since the TV was going very well and I don't want to disagree with it. If someone can help me some kind of reset or something I would appreciate it. regards

Hi. Try first to get the eprom memory data from that tv and re-record it, saving the software it has previously ... or putting a "virgin" memory with new data.
