20 Most Recent LG 42LH3000 42" HDTV LCD TV Questions & Answers

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.

Maybe the disk is not compatible with the DVD player version

It can't be done. The DVD remote will be single frequency for that device only and the LG remote for that LG Blu Ray (or series) only. Companies don't make cross-control between makers easy. The only exception is cable and satellite boxes to allow their remote to also control the television.
