Sounds like your DVI converter. DVI provides picture only, no sound. If your TV has an digital optical input socket, it's best to connect PS3 to TV using this, then digital stereo sound should be yours..

Is the HDMI port 2 work? Try to turn it off and turn it back on. If it is still not working then the HDMI ports have gone bad. You will need to replace the main board.

You might want to try a factory reset on your PS3 = turn it off then hold down the power button for 5 seconds it should then Beep.

there is a small memory in the PS3 that stores info about the tv that is was Initially setup on. IF you do this reset this should allow you to connect it to your Acoustic Solutions tv via the hdmi cable.
Another Tip i would do is connect it all up with it turned off then power up your appliances once its all connected.

Hope this sorts it out for you

This is quite tricky as it was working until last night and suddenly stopped receiving signals. What can happen wrong?
Do you have any other Player or other HDMI cables to try out. Sometimes the cables would be damaged or PC may fail to detect the HDMI.

Try this out from Philips helpdesk where there is new SW and FAQs are available.
