Hi , I currently have a fat PS3 BC . The main issue is no hdmi ,av works perfectly. A local company had it for 4 months and allegedly change the hdmi chip. I managed to get it back from them and it now has more issues. Front power button doesn't work which I think I can sort .secondly it won't play PS2 games I just get a blank screen and need to reboot. PS1 games play ok . Dvd movies play ok so don't think it's the drive. It's currently running evilnat 4.92. What's the procedure for testing the hdmi chip . Cheers
