Some time ago, I misplaced the remote on a MANTA LED2204 TV, causing the green button to break. I managed to switch channels and volume using the decoder remote from LINBOX AVIRA HDTR 875. For days now, the screen displays white, blue, red, green, and black colors in rapid succession, changing every three seconds. When the TV was operational, I could power it on by pressing a button at the top or using the scroll button on the decoder, even though the remote was supposed only to control this specific device. Activating channel changes with the decoder remote opened the settings menu, but it didn’t help since the menu was tied to that remote. The behavior of the decoder buttons felt completely random. I began testing various buttons, and suddenly the screen showed an unusual pattern—a detailed display about the TV and its colors appeared on the entire screen every three seconds. Now, after connecting the TV to power, it turns on instantly, showing the same color sequence in the center. There’s a message reading “no signals,” even though the decoder is connected and all remote buttons stop responding. Is there a hidden mode or a malfunction preventing the TV from functioning properly?
