LG 43UK6470PLC No Picture

[Bloopeta]

LG 43UK6470PLC, TV powers on, backlights illuminate, has sound, but no image, just blank screen.

Have tried unplugging Left and Right ribbon cables one by one, no change at all.

Just wondered if its a dead panel, or possibly something else, as previously when I have looked at TVs with dead panels, unplugging one or the other ribbon cables has given me half a screen.

Any help grately appreciated.
