Messed up Macbook screen - please Help!!!

[deargodpleasehelp]

Hi, before you think my screen is busted and needs replacing, It's not completely busted,
it is very dark and I cannot change the brightness, I am using an externel monitor right now because it is impossible to use it at all without it.

I am thinking this may be a Backlight issue, Either way I'm not sure and I really don't know (what to do).

Specs of my Macbook:

OS:            Snow Leopard 10.6.4
Processor:       2.4 GHz Intel Core 2 Duo
Memory:         2 GB  667 MHz DDR2 SDRAM.
Model Identifier:   MacBook4,1
Graphics Chipset Model:   Intel GMA X3100

I don't know if I can give any more info than that for help, I just got the spinning ball of death and Finder is going to crash any moment, so let me post now, will edit later.

Thanks for the help, I do not know what other info I can give, if somebody can help me that'd be great.

Switching to Mac wasn't easy lol.

Sounds like your Display Inverter is damaged. Bring it back to the Apple Store.

But I don't have crApple care.

Apple Care is a free repair and warranty service. If you take it back to the store, they should be able to repair it, but it'll cost you.

It might be worth getting a new laptop. You can use Time Machine to transfer everything to the new Mac.
