I have a LG 42" LCD and the LH_RH7660ia sytsem , and have been experiencing a full screen flash from time to time. i dont lose audio quality but the picture just flashes brighter for a split second. I have spoken to my local LG Technical and they said to remove pin 8 on the scart lead. I did so and still no joy. They are now saying that it could be a compatibility problem??? Is this true or is it that i havent set the system up correctly? some help or response would be greatly appreciated im pulling my hair out.
