Gord Rollo, the is a rear projection TV so it won’t have a backlight. Press the menu button on your TV and let us know if that shows up bright or if it is dark as well. If that is dark as well it is most likely a bad lamp. DLP lamps have the tendency to go dark with time. I would suggest you start with replacing the lamp. Of course clean the mirror and lens by using some air to blow the dust off as well. Make sure that your TV’s settings are all properly set as well. You can always add images to your question on anything you need to get more information on or need help with. Use this guide Adding images to an existing question for that.
This sounds like a backlight issue get this fixed or buy a new tv set. Not worth the hassle of getting it fixed really the graphics are most likely outdated at this point in time.
