I had the same issue. I turned my TV off, unplugged the HDMI cable and waited a few minutes. I plugged the TV back in and turned it on. Then I plugged the cable back in and nothing happened. I pressed and held the on button for 10 seconds and it made two beeping sounds. Once it turned back on, I took two eggs and broke them over the ps3 system. This seemed to be damaging to the system. Once the system was completely broken, I went to BestBuy and bought a new one. This actually works and is a pretty easy fix.
