I take a long time before I make a purchase like this TV. A little over 3 years ago I bought an Integra DTS 7.9 receiver with the idea that when I upgraded my TV down the road I wouldn’t have to get a new receiver. I would be able to route all my equipment through the receiver, only having 1 HDMI cable going to the TV and having an on screen display from the receiver. When changing sources I would only need to switch inputs at the receiver and not the TV too. No more RCA, Video, Fiber Optic or Component Video cables going to the TV. I’d looked at this TV for awhile and was very excited when it went on sale. When I hooked it up as instructed everything was awesome…. for about an hour. Then the video signal dropped out but the audio stayed on. Turning the Receiver off and on brings the video back on for a short time (1-15 minutes) before it goes out again. The same thing happens when the source is the Blue Ray set on high definition signal. If I run the HDMI from my cable box or Blue Ray player directly to the TV it doesn’t drop out, but I have to use fiber optics to connect audio to the receiver. Initially I suspected the receiver. I talked to the guys where I bought it and they were surprised I was having problems. I tried more fixes than you can imagine. Finally they asked me to bring the Receiver in to them. With their Blue Ray player and TV (Not a Sharp) the signal never drops out. They literally ran it all day. So when the video cut out again at home I took the 42 inch Insigna HDTV from my bedroom and hooked it up in the living room. I too had no signal drop out and watched it for hours. I have talked to the Best Buy Store and called Integra about it and neither had heard of any problems like it. I spent hours on the phone with the Sharp personnel trying so many things and nothing has changed. My Cable Company said they have seen it a few times before because “with HDMI, some products just don’t communicate well with each other.” I’ve given up and now have to use the multiple connections hookup. So in the end, including my Paradigm speakers, I have several thousand dollars worth of Audio and Video equipment in my house that are nice, but don’t do everything as they should. I know it isn’t a major tragedy in the overall scheme of life’s problems, but it is disappointing. I would equate it to buying a Wifi TV and being told, well, if the Wifi doesn’t work you can always just run an Ethernet cable to it! Or, if the water is out in the shower, just run a garden hose to it to wash off.
