I bought an old PS3 with hopes of fixing it because the symptoms it has resemble that of a burnt out power supply. So I bought a power supply from eBay pulled from another PS3 (same model APS-231), swapped them and it fixed nothing. Is there something I'm missing here? Below are the issues: No light when plugged in Pressing the power button while plugged in will briefly turn it green and you can hear the disc drive booting up, but then it will abruptly shut off Eject button just makes the typical sound when there is no disc in the system Happened to notice this, but the Blu-ray drive is kind of loose. Is this supposed to be firmly secured? If anyone knows what my next course of action should be, that'd be awesome. Thanks!
