Problem in console or control?

Sounds like you have a faulty console. I'd recommend sending it in for a repair at myservice.xbox.com

Thank you Brad for your answer

X, Y, B, and A buttons plus the cross on the left (i don't know how to call it) work for some minutes and then they stop working .

Very weird because all the others works

Unfortunately it didn't work and now the controller when it connects after a very long time flashing, it doesn't work as I said before and now it makes also the icons on the Xbox home flashing and it moves randomly

Just the same unfortunately

[quote user="LordDarknetcs"] I'm always connected through play'n'charge cable with no batteries in clip[/quote]You do still have the battery pack in the back of the controller, though, correct? Even when empty the pack should be on the controller if you're
using the charging cable.

and problem occurs with both pads, and don't disappear even when I turn off game (by ejecting disc) and go back to dashboard, only solution is to reboot console,

Why wouldn't you try unplugging the power cable and then
reattaching it? That would force the controllers to sync up again with the console.

because when i plug them via playn'n'charge cable to my PC they works just fine.

You mean when you power the controllers from a PC USB port, they work fine with
the 360 for extended periods of time?



It sounds like your 360 is having trouble keeping the controllers powered continuously. Perhaps invest in a set of rechargeable batteries and a charger? Then you wouldn't need to power them via the P&C cable.
