LG model - 43UK630PPE Every 15 minutes or so the screen turns grey. Can still hear the program but cannot see. To fix required to turn tv off and back on. Good for another 15 minutes or so then back to grey vertical bars. Suggestions as to how to fix appreciated.
@david_ph1 intermittent errors like the one you are describing are a big PITA :-). The issue here could be the T-con board or the Main board. Remove the back of your TV and take a look at the boards. See if there are any components that may look discolored or “odd”. Post some pictures of those with your QUESTION. The other thing you can try is to use some freeze spray. If your TV starts acting out spray some of it on the T-con board and see if that resolves it temporarily. If not try the same with your main board. Again, we may have a more precise answer when we see more of what your boards look like etc. Be careful not to touch anything with your bare fingers while you work on your TV since that might be a shocking experience :-) Adding images to an existing question - iFixit Repair Guide
