Okay found a "solution" or "temporary work-around".
If I changed the input to
HDMI (DTV) instead of
HDMI (PC) I was allowed to manually change the settings for height placement of the input.
HDMI (DTV) has the problem of being constantly zoomed in and I was unable to zoom out, but if I changed it's height placement value and then changed back to
HDMI (PC) it remembered it's placement from the
HDMI (DTV) settings.
I have not yet tried turning it off and back on and see what demons that spring up when I do, but for now it's fixed.
Also;
I found out how to go into the
Service Menu, but none of the 6 standard LG passwords worked for me, presumably the person I bought the TV from had changed it. So if anybody happens to know how to factory reset an
LG 42LB1R-ZE without needing to reach the service menu, I'd be greatful to know.
Today's post brought to you by the letter: "heck".
