LG 42LK450 no video

Both sides of the screen no video? I would look at the TCon board first. Something common to both sides.

Left side works. No right.

There is a "tape" method to isolate the X driver from the bad side (strangely, the display will still run with the other side driving).

There must be youtube videos about adding a small bit of tape under the ribbon cable.

The other way is to remove the front mask to expose the side ribbon tabs on the bad side. With a *new* XActo blade, cleanly cut off all the ribbon tabs on the bad side. Careful not to pull the tab while cutting - it's got to be clean.

The tape method is safer and reversible, the cut method is 100% but not reversible if the ribbon is pulled on the display.

My 70" Sharp is running with one side after I cut off the other side tabs.
