On the inside of the TV, on the flyback transformer there should be two controls. Turn the one that says "screen" very slowly clockwise while looking at the pix. The pix should get brighter as you turn it up- if you go to far you will see lines in the pix or the TV may shutdown.

Try turning up screen voltage with control on transformer....
one is for more brightness and one is for focus.......T.

Ive had a similar model since 2002 and it had the same problem. Factory power supply to weak for the model. Mine was replaced twice before the upgrade came out. Sorry, I dont think it is a $.50 solution.

To do this, press the ENTER button on the TV and the MUTE button on the remote at the same time. After 5 seconds the screen should come up and it will read "Lamp use time...Total lamp use time ....lamp reset" Press the center button on your remote (the circle button right in the middle of the four directional buttons) and you will be reset to -0- again. Your orange light should now be off.
