Audiovox AVT2540 won't turn on

try unplugging everything for 10 seconds and starting over, TV included

The first thing that comes to mind is that the brightness and contrast or turned all the way down. See if you can't turn them up. Otherwise it may be the backlight inverter or backlight itself. Most likely the inverter, sometimes you can tell by looking really close to the screen, if you can still see a faint image then the inverter needs to be replaced. Probably a job for a technician but that depends how comfortable you feel opening up the TV and ordering parts online.

Good Luck!

Having to unplug suggests a issue where the set is getting confused, if using any kind of box for signal or have a receiver in line remove power from all and after several minutes plug back.

What source are you using? If cable, you should only be able to pickup channel 3 or 4 if you're using the box. If there is no antenna, that would be the only other answer if the set checks out...accordianman
