Just replaced my led backlights (because of blinking) and now that the blinking is gone I now have a huge vertical band near the centre? Have I damaged something?
@urga check the thin ribbon cables that go from the LCD driver board to the panel. Check the ribbon that corresponds to the particular area on the screen. Press on it and see if it makes a difference. This is most likely an error with either the tab or the board. The driver board is the one where the ribbon cables from the T-con board connect to.
