Question about Panasonic TH-42PD50U 42 in. Plasma EDTV
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.
