White screen with good audio. before buying pcbs & such. try my repair method.. you need to get the lcd unit off the facia & then remove the front lcd metal frame. at the top of the screen you have 2 thin pcbs - chances are that the ribbon cable got at least one track unbonded. first off put some double sided tape under the pcbs to stick then to the frame - that'll take the bend out of those pcbs !! next put cellotape over the ribbon cables. i then cut 6 pieces of sponge 15mm thick & wide as the ribbon cable & glue to the tape on the ribbon at what would be the top edge of the screen (covering the point where ribbon meets pcb).. put the metal frame on top edge first to keep the sponge straight !! put it back together & fire it up. if it still aint working you may need a tcon pcb (little square one at the top). this fixed my 42lg3000 but can work on others with same fault !!

Most LCD and PLASMA sets use two boards (some combine them into one board) that drive the Display Panel (the entire front screen unit) so I would suspect one of yours is bad.
The other unpleasant possible cause is where the left board is connected to the Display Panel (entire front screen unit) you have a problem inside that Display Panel and that is fatal as there is no way to get INSIDE the panel---it can cause both lines and a dark picture on one side of the screen.
