LG 42LH3000 42" HDTV LCD TV Questions & Answers
42lh3000 Right half of screen is black but goes better when warms up, still flickers at times, how can i repair this?
I have fixed an LG 42LH3000 with this very problem. Large TVs have a tendency to flex and bend ever so slightly when being moved or through heat, this can affect the connection of the ribbon cables at the top of the screen - either at the end where the Tcon board is or where the screen driver board is. When one end of the cable loses contact, half the picture goes (there are two ribbon cables. one for each side of the screen).Remove the cables then carefully reattach them. If you still have an intermittent problem would suggest leaving the screws out of the T-con board as this will give the ribbon cable more slack.Don't attempt any of this unless you know what you're doing - risk of damage to screen if handled indelicately also risk of fire when plugged back if the ribbon cables aren't secured properly.

Sounds that the backlight inverter board has damaged. Read more details about this fault by this site 'Electro-help' It is an electronics equipments service help site. Google for it. Pull up older posts there.
