After 14 months I began having the exact same problem as many other owners: After initial startup with the "Please Wait" message displayed the screen goes blank and only audio comes through. This happens about every third time we try to use the set. SHARP customer service pretends they don't know about this problem even though I suggested they google their own product or even look at the Amazon reviews. My set was at a repair shop for over a month and they decided they couldn't fix it.
