Well I still have to have my av cables plugged in to the see the message that it's detcted a hdmi connection, but if i slect i just get a black screen like the signal is detected but nothing shows, i take the av cables out and there's till no difference, booting with the av cables out it doesn't auto detect the hdmi because when i pout the av cables back in it still asks me if i want to use an available hdmi input.

Any other suggestions. I'm trying with both HDMI to HDMI and HDMI to DVI (for my monitor)

 

A resolution not supported by your TV could be why.

PS3 also requires any device connected to its HDMI port contain HDCP, even for the XMB or games. But this isn't the case if the TV is recent enough.

 

The scart option outputs through the A/V port, not the HDMI port.

 

Reset your video output.

Unplug everything except for the obvious hdmi and power cable, and hold the power pad until you hear two beeps. You should get picture then, and be able to set what resolutions you want outputted.

 

turned out it was the TV at fault, the HDMI was the problem, and it was beyond repair so we got a new HD TV on the warranty
