The other ports such as AV And TV are working
Try a different HDMI cable first into all ports. Try every HDMI cable you have. Then try a different component into TV HDMI ports. If you are using the receiver to switch inputs, try running HDMI cable straight into TV. HDMI is very finicky. Some cables won't work or stop working for no apparent reason.

On the MacBook, check the Displays pane in System Preferences to make sure the settings for the external monitor are correct. It's possible that the system is not recognizing the adapter or it has the wrong resolution setting, so it's not sending out any signal that the adapter can use.
Many of the better DVD players and high-end video game consoles use HDMI. You can use one of those as a test signal generator to check the TV.
You may get better results if you use a DVI-HDMI converter, although you would need to get the DisplayPort to DVI cable. This will avoid converting to analog VGA signals and back to digital again.

Yes you can connect your Panasonic Viera TH-42PX80U Plasma TV to your computer. You will need to buy an hdmi to vga cable in order to connect your vista desktop to your tv.
