Hello, I have a Daewoo 42 inch Plasma, everything has been ok until about 3 weeks ago. I put the screen on and the picture had gone very dark, almost unwatchable. We had had a power cut that day (coincidence??). Tried all connections and colour settings etc, factory reset etc, nothing has worked!! Is really annoying me now, any one got any ideas about what the problem might be. Is still in guarantee but Daewoo are ignoring me.
