What input channel?

Just googled your tv and that model does not have a HDMI port. The highest quality video input are the component ports.

How are you hooking it up to your TV, through the AV color cords or HDMI, or HD AV cords?

First, make sure your TV is on the appropriate input for the plugged in HDMI cable. Once this is completed, turn your ps3 on. If the screen comes on and is black, turn the ps3 to standby (red light is on) and hold the front power button until the console beeps a second time. This will usually force the ps3 to recognize the hdmi input and will bring up the menu to configure the AV settings.

What is probably happening, is your PS3 is set for the wrong type of output. If you are using an HDMI cord, try switching to the AV cables that came with your PS3, and set your TV at the appropriate input to correspond with the AV hookups, and see if the picture works then.
If you are using the AV cables, it may have been set to HDMI accidentally. You need to use an HDMI cord, and hook the PS3 up to an HDMI compatible TV or monitor, and select the HDMI input. Once you get the picture working, go to Settings>Display Settings and set the display you wish to use.

You need to check and make sure that you are trying to view the PS3's output on the proper channel or input on your TV. If you need to scroll through every channel and input.

If that doesn't work try replacing the A/V or HDMI cables. If it still doesn't work you may need to send it to Sony and have it replaced. The video output section of the console may be bad or not functioning correctly.

If you have a friend with a PS3 try to see if they will bring their's over and let you test it out. If their PS3 won't display then it's something wrong with the wires or the TV.

you need to connect both the yellow red white cable and the hdmi cable into your ps3 and go the yellow red white av channel

go to the ps3 settings and change the video settings (ithink) to hdmi and also change the sound to hdmi

the screen will go blank and then the tv should change to the hdmi av channel if not change to it and accept the changes

ps3 comes with an av jack set as well as hdmi. now you can use the hdmi to the TV and run audio out from the TV to the receiver and that should work but if you don't have audio out on the TV then you need to go get the av cable

connect back to your old tv and reset the ps3 to default settings then connect to your new tv.

this is a very simple fix leave cords in your sony with ps3 on standby hold the power button on ps3 itself down for 10sec your ps3 will switch back to av cables

All: Try this -

Perform the following steps to reset the Video Output Settings.

1. Make sure the HDMI cable is connected to the [HDMI OUT] port on the back of the PLAYSTATION 3 system. Connect the other end of the HDMI cable into the [HDMI Input] port of the TV or display monitor.
   
2. While the PLAYSTATION 3 system is in standby mode (red light on the front of the system), hold down the touch-sensitive On/Off button on the front of the system until the system goes into standby mode again . (So the light cycle would go from: red light to --> green light --> then back to red light) This will ensure that you have held down the On/Off button long enough to reset the Video Output Settings.
   
3. Turn ON the PLAYSTATION 3 and once the system finishes powering up, the Video Output Settings will automatically reset to the standard resolution (or detect the current display output settings of your TV/monitor). [If resetting does not auto-detect your HDTV, see next step below.]

NOTE: As of system software update version 1.60, the PLAYSTATION 3can automatically detect an HDMI connection to a TV. If the PLAYSTATION 3 is turned on with an HDMI cable connected, the screen for switching video output settings will be displayed automatically. (Does not function unless the TV that is connected by the HDMI cable is turned on.)

As of version 1.80 of the system update for the PLAYSTATION 3, the PLAYSTATION 3 can upscale the video content of PlayStation® format software, PlayStation®2 format software, and DVDs to HD resolution.
If Resetting the Video Output Setting Did NOT Detect Your HDTV Automatically (Certain TV's Only)
With certain televisions, the PLAYSTATION 3 may not automatically detect the HDMI source (TV) which it is plugged into, even after resetting the Video Output Setting (as described above).

If resetting the Video Output Setting did not work, you may need to follow these steps to manually locate the HDMI source:

1. Connect both the AV Cable and the HDMI cable from the PLAYSTATION 3 to the corresponding (AV and HDMI) ports on your TV. 2. Proceed with resetting the Video Output Setting on the PLAYSTATION 3 again. (Follow these steps, then continue to step 3 below.)
3. Turn the TV channel to the corresponding "Input" or "Video" channel for the AV Cable connection.
4. Manually change the Video Output Settings to HDMI. (Follow these steps, then continue to step 5 below.)
5. Now switch the "Input" or "Video" channel on the TV for the HDMI port the PLAYSTATION 3 is currently plugged into.
6. Accept the display settings for HDMI before the timer runs out (30 seconds). Highlight "Yes" and press the X button.
7. You can now disconnect AV Cable from the PLAYSTATION 3 and the TV, as it is no longer needed.
