Please help! My father-in-law has a LG 47LE5400 TV that has suddenly stopped responding to the remote and won't turn off at the screen either. We turned it off at the power supply and when turned back on the menu option comes up momentarily then disappears. You can't change channels etc when it is acting this way or access the menu screen from the tv selection or remote. After some time (maybe 30 minutes or so) the remote will then start responding and the options on tv (volume, on/off, menu) respond if you press them as well.
My husband I have tried everything and have never seen a TV act so odd. Has anyone else had a similar problem? Please post if you have as my elderly father-in-law is going to drive us crazy if we cannot find the source of this problem!!!
