This is another project ,I have a 42lg5000 tv which when first turned on has a very thin green line vertically on left side and a dark shadow on the right half of screen even though can still see picture there and picture on full screen, when i leave it on after 10-15 mins and not touched or moved it the picture goes ok and has good picture with being able to watch it all night with no bother .see pics. The second picture is after 15 mins and stays ok till tv turned off, Then same thing repeats over again next day ,Its as though some chip is ( dodgy ) warming up then works ok but i could be wrong.
Hi @moggy01 It could possibly be a loose tab on the panel or a faulty TCON. Suggest that you search online using just the board number of the TCON board as the search term to first see how much they cost and if they are readily available. Keep this in mind and then decide if you want to access the panel to check the tab connections (it will be near where the line is on the screen - there are plenty of videos online on how to do this for LCD panels) or risk the expense and pay for the new TCON board and see if it fixes it.
