Hi, I am having similar problem with my CECH-2006A. I am able to play GTA 5, Bioshock infinite, Bioshock, Bayonetta and black ops 2 with no issue, but it will auto shut off, beep 3 time and flashes red light when I tried to play red dead redemption, metal gear rising, binary domain, infamous 2 and RE6. It always shut off at the exact same spot in the games every time. All the games i used are PKG install. It was not overheating as the temperature was at around 65 degree Celsius when it auto shut off. I do not think it was YLOD either as i did not see any yellow light at all. I tried changing power supply and swapping hdd but it is no use.
