Macbook Backlight issues

So, yesterday, my backlight decided it only wants to light up intermittently. and only for a little bit at a time. screen seems to still work, but when i open from sleep, sometimes it will flicker on the right side (like a fluorscent bulb) and go out again, or light up completely like it is supposed to, or do nothing at all. Machine is over 2 years old, and has gotten a lot of use. What are the chances this is a relatively cheap (1-200) fix?

The machine is in good shape otherwise except for palmrest cracking which i havent gotten fixed due to the fact there is no apple store within 100 miles...
