Query: Dark Screen Solution

We had the same problem as others where the screen never started displaying a picture. I had a service agreement so I called to get fixed. Sharp issued a service bulletin. Basically, it's 4 screws that are slightly too long and are grounding out. I don't know more than that, the service tech wouldn't give me more info.Hopefully you can call Sharp and get the info.As for a review, I think it's a great TV. The picture is great and we're really happy with it - now that we've solved the black screen of death!Good luck
