My TV’s right hand side of picture is missing about a 6th of the screen in total. The picture test function does not display it either. Instead of displaying the picture there is a cluster of what I would describe as black, white and grey vertical lines. Apart from this the TV is functioning well. The T-Con board was replaced but this did not fix the fault. If anyone has any ideas I would be grateful. Thank you in advance for your assistance.
Paul that sounds like a bad LCD driver board. that is the board that connects the panel to the T-con board. You cannot replace that board since it is connected to the panel via a special process. Gently press on the cable that enters the panel in the area where the picture does not show. Let us know if anything changes. If you can let us know what panel this is (check the label on the panels back) and post some good pictures of that driver board with your QUESTION. Also, we will need to know what exact model your LG TV is. Adding images to an existing question
Thank you for your reply much appreciated. Well I took the led panel out and it’s 100% a fault with the panel. I noticed, I’m guessing the bonding is coming away on the right hand connector just on the edge where the connector goes into the screen. Pressing firmly had no effect. However, running my finger nail on what looks like a white rubber compound did (it’s actually come off in large quantities on the left and right side of the screen, leaving a bronze/gold effect). The display moved with my finger nail, but never enough to show all the display. The back of the LED screen does not show part numbers, but now I know what I know I suspect this TV is for the bin, as an uneconomical repair due to the TAB connector process and the fact I don’t have the necessary equipment to repair it. I can send the pictures if you wish which will take some working out as I am new to “ifixit”. Thanks for your help.
