Ps3 Controllers Unresponsive

[alb0679]

Hello all.
My sons PS3 has developed a problem. The system will switch on, however the controllers are not working. When I plug the controller into the console to charge the flashing red lights indicate it is charging, is that correct? Despite this, the controllers will not then switch on after a prolonged charging period.
Any advice appreciated.
Thanks.

Controllers or controller? If it’s more than one that isn’t working it seems highly unlikely that both have failed.
Are you switching on the PS3 using its power button or the PS button on the controller(s)? Trying the latter, you should hear a beep and see all 4 LEDs flashing on the back of the controller.
If that fails, have you got a USB keyboard? You can plug that into the PS3 and use its arrow keys to navigate to the Accessories menu to check the controllers are registered.
