Hard to say... if you can DIY it then maybe. The backlight needs attention first, could be the actual "tube" that has broken or just a connector become dislodged. You need to be sure the screen is totally undamaged as that would be costly.
As to the hinges and cabinet you would have to see what was available.
I wouldn't go spending large sums paying for a a repair, and you need to confirm it really is 100% operational on all functions.
