Problem could be the thermal fuse cutoff on top of the lamp assembly. Has two wires going to it. A good test is to remove one wire and connect an alligator jumper to the two wires by passing the thermal fuse cutoff and see if it will stay on.

On right side as you look from front is door secured with at least one screw; with set unplugged remove door and two more screws behind it that secure the lamp cartridge (it has a handle) and carefully pull it out----replacement lamp comes in one of two ways= just the bulb or the bulb with the cartridge.
Get the one with the whole cartridge, much easier to replace and "generic" ones are no bargain as they usually have a shorter life.
Carefully insert the new cartridge in being sure the two pin plug on the back engages correctly; NEVER TOUCH THE FACE OF THE LAMP WITH YOUR HAND as oil on your fingers can damage the lamp when it operates.
If you search the internet with the model number you will find a lot of sources for a replacement lamp.

It is most likly an optical problem with dust or a haze onthe optics or a bulb problem or could be a bad LCD display. If I were youand if you are handy, get a service manual, look at how to disassemble theoptics and light housing, and clean everything first, but NEVER ever sprayanything onto the optics and use just a slightly damped soft cloth, never anypaper product. Or the way the pros recommend is with compressed air, butif it is canned air, be careful, as those things get cold and you can easilydamage something. In a good camera storethey will have a bulb type blower to clean lenses off .

If I knew the Model I could guess better, if it's only the brightness, why don't they fix, I would guess if much more, if floor model meaning the tube tv or CRT then it could be fixed easily if you know what to do, but if it's a flat panel then you are looking for a board probably. Either way 50 is not much.
