hi guys,

i have a problem with my ps3 slim video output because it shows a black screen and no sound
but it was ok the last time i game which is about a couple of days before.

tried reset video output by holding the power button until second beep, nothing happens . no video no audio

then i use stock ps3 slim av cable, it turns out ok and with a message stating the ps3 detects a hdmi output.
choose yes and change to tv hdmi channel but black screen happens again.

hdmi cable is fine . tested it with astro decoder to the same tv and tv hdmi port.

any thoughts? 

Anyone knows how to deactivate or remove a controller during a game?

Eg while 3 player playing little big planet, one player wants to quit. How to remove the controller? I tried checking game settings and main menu accessory setting...nothing
