My 39 inch 2014 39 inch LG had both HDMI ports giving 'No Signal' message after a lightning storm. The Component/composite input worked fine.
LG 39LB5600-UZ Need help accessing Service Menu
I replaced the system board and the HDMI ports are now working, However the picture is rotated 180 degrees (upside down) . Everything I have searched says to enter 'Service Mode' and select the Mirror option and change it to Off. This TV does not have a set of switches on the TV, only a small Joy Stick at the base. None of the internet "secrete" ways to access the Service menu work.
A couple internet hits say I need a MKJ39170828 universal service remote.
Any help or direction would be greatly appreciated.
