I decided to upgrade from a 40gb hdd to a 120gb hdd. I backed up all my data on an external hdd and started to remove the 40gb hdd and put in the new one, then I hooked up all the cables and started the system. When I turned on my tv I noticed that it says no signal and the system is on. I tried to turn the ps3 off and turned it on again but the same thing happens, there no picture on the screen with the system on. Then I thought that maybe the reason why nothing happens is because the new hdd doesn't work so I put in the old 40gb hdd and there still isn't anything on the screen. I checked online on google and I see that it says to hold the power untill I hear three beeps and that should reset the setting and I should get it to work but I tried that and still nothing. Someone please help me with this because it was working before I changed the hdd and now it doesn't work with the new hdd or the old one. I also tried connecting the ps3 to another tv and it still doesn't show anything. The ps3 doesn't show anything wrong becuase the light turns green when I turn the system on and I can put a disc inside the cd drive and I can also take the disk out so I think that the system is running correctly but I can't see or hear anything. One last thing is that I also tried using different cables and slots on my tv and still nothing.
Any suggestions are good right now
