PS3 and movie play back problem?

May be...

I am trying to play a Blue Ray movie with my PS3 . It will run fine with the AV cable but no picture will show with the HDMI cable. Can some one help.

You need to turn it off, leave the power button pressed for about 5 secs and when you hear a series of beeps it'll reset and set the correct resolution with the hdmi cable.

you have to change your settings to HDMI: go to display settings, change the video output settings to HDMI and you have to make sure your tv is on HDMI1 or HDMI2, once you change your settings on your ps3 the tv has to be on one on those or it wont work

trade it in for an xbox 360
