hi all ps3 phat cfw 3.55 kmaew installed. wont boot up, green light comes on, fans kick in for about a second then they stop, green light stays on constantly, cant power off unless done at the back, tried holding down the power button to access recovery menu with no joy, also tried holding down the power button to get the 3 beeps to restore video setting, i get the 3 beeps but still nothing appears on the tv, tried composite leads and hdmi leads with the same outcome which is not a sausage. the leads are fine as ive checked them on a friends ps3 also. the ps3 will take a disc and you can hear it inside spinning and the laser reading it but nothing on screen. any ideas?
