Note: How to reset video output settings
If you are attempting to change to an HDMI cable from a different video cable or if the video output settings do not match those required for the display in use, the screen may stay black. If the screen stays black for more than 30 seconds, you may need to reset the video output settings of the PS3.

To reset video output settings:

1. Turn the PS3 system off by holding the Power button on the front of the console till you see the power light turn red.
2. Then hold the power button on the front of the console for at least five seconds until you hear a second beep to turn the system on again. The video output settings will automatically be reset to the standard resolution.

Minimum Requirements

• PlayStation®3 computer entertainment system
• SIXAXISTM wireless controller (and USB cable)
• AC power cord
• HDMI cable1 (sold separately)
• TV or display monitor with HDMI port and capable of displaying picture in HD resolution
• Updated system software installed on your PS3
  Visit PS3 System Software Update to download and install the most recent version.
• TV "Input" or "Video" channel for the HDMI port
  You need to know the TV "Input" or "Video" channel for the HDMI port on your TV. For instance, if your TV has multiple "Input" or "Video" channels, (i.e., "Input 1", "Input 2", "Input 3", etc.), you will need to toggle through each "Input" channel on your TV until you find the correct channel that displays the HDMI picture. This is important to remember, especially if you do not see the HDMI picture after you connect the cable and configure the PS3 settings. Please refer to the TV instruction manual for more information.

First, set [SWITCH TO ANALOG I/O] to [OUTPUT]
then turn off the (camcorder) unit.

After you connect the cable (from AV connector to the TV's AV Input Connector (accepting the 3 color cables), set the TV to VIDEO mode, selecting the AV input (from your Camcorder).
Then start your playback on the camcorder ...
slide the mode switch to select the (video) mode (instead of the picture/photo mode)... press the PLAY/REC to select the playback mode, and select the desired files/frames to play.

Hope this works for you. Have you tried using the HDMI mini connector instead ? (same process, just set your TV to accept input from the HDMI input)

The sensor bar cable and the RCA cable can be ignored for this problem. In fact, just disconnect them and go with just the power cable. If you are getting power to your Wii, it will display a green power light on the front when you power it on without the sensor bar or the RCA cable plugged in. (It should also display an orange light when it is off, if it is getting power from the outlet.) Take the Wii into another room with working outlets and plug it in. Attempt to power it on with the power button on the Wii, and with a working Wii remote. If neither will power the Wii on, try borrowing a Wii power cable from a friend, or purchase a replacement. If the new power cable does not fix the problem, see if the Wii is still under warranty and send it in for repair.

returned defective unit to the store after talking to them and determining the menu would not display.

this happened to my tv once, i ended up replacing it
solving it yourself may cause severe burns, electric shocks and even death, so i recommend you to letting a professional check it out

Not really a solution, but a workaround. You can enter public mode menu and disable power off by power button. Hold the remote in one hand (you'll need it later), and with the other hand maintain "volume " and "input" buttons on the TV, and press the power button. Maintain the power button depressed otherwise the TV will power off. You can release the other buttons. The TV should display a "Public mode" dialog box where you can input a 3-digit password. Enter "027" with the remote. The TV should display the public mode menu. It is operated with the cursor arrows of the remote. Highlight the "power on fixed" item. Change it to "fixed". Then highlight "execute" and press OK on the remote. You should now be able to release the power button without turning off the TV.
In Sharp's own words :
In "Fixed" setting, the power-off by the power key of the unit is invalidated and the image is kept being received. The power can be turned off by stopping the power supply from AC.
Note that you won't be able to turn the TV off with the remote either.
Also, if you wish to enter public mode menu again, you will have to disconnect and reconnect the power cord on the back of the TV while maintaining "volume " and "input" buttons depressed, because the power button is no longer operating.
