There's another thread on here about it, apparently sony have said theres ways to fix the problems, one is the hdmi port, theres a metal bit that might need bending back in to position, thats if u get no output on your tv, i cant believe that, pay over 300 quid and you might have to bend abit of the hdmi port into place, the second issue apparently is red lines, this is a safety feature built in to let you no the ps4 is over heating, you need to then let it cool down, Sony says its 0.4% of ps4 s suffering from the above problem, not sure how accurate that is but its all over the internet about problems, really hope mines ok when it arrives, some people are getting this over heating after a few minutes, others a few hours,
