Hello,
sometimes using the hdtv mode on my hdtv on many channels the picture blinks black constantly while on other channels it does not. when this happens i have to switch to coaxial mode. I use hi quality hd connectors and I have replaced the cable box but get the same results. The tv is LG HDTV. manufacturer says it is the cable box. Can someone tell me what is causing this
