The main reason of HDMI black screen problem due to HDMI cable may damage and not proper connected to the PS3 console. Please follow below step to troubleshoot PS3 HDMI cables problem:1) Restart your PlayStation 3.
2) Look for loose cables.
3) Try to unplug all cables except the power cord, and plug them back in. If you found out that your HDMI cable is damage, do borrow your friend cable and have a try. If your friend cable work fine, and the black screen error disappear. Then you can buy a brand new HDMI cable for replacement.
Tips 2: If tips 1 not working, you need to go another step deeper by reset your console. Most of the PS3 gamers not aware that Sony actually done include in the black screen troubleshooting method and other HDMI problems in the PS3 manual, you can find it under troubleshooting section - topic "console reset".
If you do it correctly, the console reset fix will allow you to reset back your PS3 to its default HDMI settings without impacting your gamer profile, and other storage data in hard drive.
You will need to perform the following steps:

1. Place your PS3 in stand-by mode.
2. Hold down the touch power button until a series of beeps are heard.
3. Listen for one long beep, followed to two shorter beeps.
4. Release the power button.
5. Follow the instructions on screen.

You will need to turn on the PS3 and hook it up with rca so you can access the console menus. Turn it on and get to the main dashboard. 1. Go to Settings -> Display Settings (not video) 2. Select [ Video Output Settings ] 3. Select HDMI 4. Select Resolution 5. Select Screen Size 6. Save the settings 7. Reboot the console. This should resolve the problem. We've seen PS3 consoles that would not reset by performing a hard reset. We were able to resolve this issue through the settings menu though. Let me know if it is still giving you issues.Hank GATpro Repairs

Try entering Recovery Mode and choose "Restore Default Settings".


If that doesn't help, you may have an HDMI port failure - which will require returning the unit to Sony or sending it to a third-party PS3 repair shop.

hook up computer straight to t.v with hdmi cable. then get two aux cables (usually red and white) and run them straight from tv audio OUTPUT to audio INPUT on bose system. them anytime you want surround sound even when your watching tv just press the aux button on the bose system controller. should be perfect.

Is your tv hooked up to your cable box or satellite with an HDMI cable? There are several ways to input to the TV.

When using the HDMI connections you may have to tell the DVD to output to that port.  Also you may have to connect additional sound cables from the DVD output to the TV.

Have you try to replace your HDMI cable?I recommend you to pick up a good Monster HD700 HDMI cable from a local retail store like best buy or circuit city.In case it isn't the cable problem,you could return it.
However,when you are a using the HDMI cable,it is normally either have both picture and sound or nothing at all.Are you sure you didn't hook up the audio OUTPUT from your TV back to a receiver input?
Or even an optical output from the TV to the receiver?
