SOURCE: PS3 controller Problem

I just fixed mine. The controller itself needs to be reset. There is a reset button on the back of the controller, above the top right hand corner of the square with all on the information and barcode. Press it with a sharp tipped object while still connected to the PS3 via USB cable. Then press the PS button and you should be back on wirelessly.

The same thing happened today to mine so i rang sony. They said because i bought my ps3 when it came out as a good will gesture their sending a courier out to me to exchange it (In 2 days). Man I love Sony don't know about you guys. LOL.

SOURCE: controller not working

I had the same problem, so I called customer service and had me do this:

1) with the USB cable plugged into the controller, power down the ps3 and turn the on/off switch in the back to "off".
2) hold your thumb down on the front button (where you normally can turn it on) while turning the switch on the back to "on" again. keep your thumb or finger on the front switch.
3) You will hear the normal "beep" that you usually hear when the PS3 boots up, but after a few seconds later, you will hear a secondary beep. Remove your thumb or finger after this second beep and the PS3 will reset itself after a few seconds. I have a projector connected to it, so I had to set the display screen back to HDMI afterwards, but when I disconnected the USB cable the controller worked wirelessly again. The customer service rep said that this allowed the controller to pair with the PS3 again. Note: You probably do not have to have the controller plugged into the USB cable at all while doing this. I just happened to have it plugged in. Hope this helps.

SOURCE: PS3 Controller wont turn on?

mine sometimes does that, just try pushing and holding it until the options come up on the screen, then turn off controller. Then try turning it back on. If that doesn't work, turn the ps3 off when its done charging, then unplug it while its off. This should work.
