Thats kinda the issue, shoestring budget...
She is running many graphic intensive adobe suites, a new machine would be very helpful IMO.

But I applaud her for living within her means.
I am sure she has classrooms full of great new machines, but there is nothing like your own machine at your convenience and mobile.

As mentioned, I did send her off with a 4:3 ~19" LCD and miniDVI to VGA adaptor.

So I think I have the bases covered....just need to find instruction how to repair the actual issue, or even if it is possible to repair the actual issue economically.

Thanks :)

It sounds as if your sister's computer has the same issue as my Macbook. Did you end up finding whether replacing the inverter wire or board resolved the problem?
 
macbook 13 backligth

These macbooks are really easy to work on I have no joke 5 of them within 6 feet of me that have the backlight issue.I usually buy one cheap with a backlight issue and then I always have the time to wait to find one for $40 or under that is for parts but has a good screen all of which I buy on ebay and I get it all fixed up and sell for a small profit which also doubles as my favorite hobby.Now as to the issue at hand many people say the connections on logic board which I dont think so because 9 out of 10 times if you just put a new lcd on it it will fix it.My best luck has been with inverters but sometimes it only betters the issue and what I mean by that I think it just puts a little more power than the weak inverter to the ccfl which is the source of the problem.I know that money is an issue but if you hunt hard on ebay you can find a parts macbook with a good screen for a really good deal if your really handy at electronics repair you could attempt a ccfl replacement which i think I am about to try myself since I have a bunch of lcd's with this problem.I hope you figure it out keep posted.

That’s right all the problems from the lamp backlight
but what’s strange all times i hade problems with backlight under mac ox 10.6 with low brightness work but if i go 100 percent go black so the strange thing i installed windows 7 with boot camp and under windows 7 no more problems with backlight work good

I've got a 2008 macbook, the display works ok but looks slightly dark at the corners a bit dull overall, it's still viewable, is there anyway to brighten it, a new display light?
