I just bought my new PS3. I have sharp TV (model: LC37A66M) with full HD support bought last year only. I got a PS3 and hooked it up to my Sharp 37 inch LCD tv using an HDMI cable. I have blinking or blank screen issues and can return to normal and play a while blicking happen again and sometimes the screen go blank and up again. I try the same HDMI cable to my xbox, no problem. So it is not HDMI cable issue I think. And I don't think it PS3 problem either since the shop has demo to me before selling the unit to me. The strange thing is my TV and xbox don't have this issues. So is PS3 or Sharp TV issue??
