Big issue here. My LCD backlight on my laptop only on full brightness will it start to flicker, and occaionally, just quit on me, having to close the lid and open it.

A few things that might not cause it:

Constant Activitiy (This might not be the case, it might just be luck, I don't know).
Turning down the brightness.

Anyway to fix this? I can't afford a laptop (This was just pretty much given to me (core duo, 1gb ram, because of this issue), and I can't afford an LCD for it.

It could simply be a bad connection, causing an arc when on full brightness, hence the flickering you see. The simplest thing to do is to carefully remove the screen front and check all the connections to the backlight.

Cant you buy the backlight itself and get it installed? I'm also thinking loose connection or a dry soldering joint

It may be the inverter board instead, that's the other thing that can cause similar issues. Does it make a high-pitched squeaking/whistling sound? Or does the screen have a pink tinge to it (the former would suggest the inverter is at fault, the latter the backlight itself)?

You can get a new CCFL backlight and keep the rest of the screen but you'd have to be very skilled in hardware to install one.

YES!! It does make the squeaking sound.

Thanks. Any recommended shop for getting an inverter board (I bought one for an iBook ages ago, so I know what they are), and approx. how much for my Inspiron 6400 LCD.

That should do the trick (if you're in the USA).

One in the UK too.

If you prefer non-eBay, http://www.getpartsonline.com/6632l-0265a.html or http://www.generalsaving.com/productfil ... L_6400.php might be useful...

The sound does suggest the inverter needs replacing then, yes, but I'll say it's worth getting a second opinion before buying one just in case it turns out to be something else, just to cover my back! Note that you will need to be reasonably skilled with hardware to open the laptop and install the inverter too, as you will probably need to remove quite a lot of parts to get to it, though if you installed the one in your iBook yourself then you'll be fine.

10 long years, frig the scene anymore.

Kids think they have deep in sources at the age of 12, why bother caring when no one receives respect anymore, they assume bullcrap, but that's all they are.
