Just as the title states I am in search for a ppc program to increase the brightness of my display. This would be for a 17 inch imac G5 amient light sensor 1.8GHZ with 2GB of ram 120GB SSD with 2 partitions, 1 Tiger and 1 Leopard. Any help would be appreciated!
 
Do you mean a program above and beyond the built-in screen brightness adjustment?

f.lux can do all sorts of adjustments to your screen brightness/temperature, on a scheduled basis, too. (See the link at the bottom "Download f.lux for PPC" for the older PPC-compatible version.)

See also Shades.
 
Tried the flux app and still screen isnt very bright (yes I've tried the brightness control from osx)
 
Then it's likely that the backlight is going out. Nothing can force the screen to increase the backlight brightness beyond what the System Preferences brightness slider can do - it can only change the brightness of the pixels, essentially "washing out" the picture by making things that should be "0% lit" as "10% lit" or similar. It won't make "100% lit" any brighter.
 
That's too bad. The images and colors seem fine but its simply darker then I would prefer. Thanks for the help though!

f.lux is more for reducing the amount of blue light in a display over time. It's not for any particular environmental adjustment although you can set certain lighting levels for night use.

Have you tried calibrating your color profile? In System Preferences under Display on the Color tab you can press the Calibrate…button and adjust your display profile to suit your needs.
 
Tried that too...

Theres no need for a brightness control program; you can configure keys in keyboard shortcuts to do that. The only use for a brightness control program like "Brightness Slider" is to make the screen dimmer than you usually can go, by darkening the color of the lcd screen itself. Nothing can make the screen brighter; you have a hardware problem.
 
CCFL backlights in TFTs tend to dim and yellow with age and usage, plus they were never as bright as the current type LED backlit ones even in their prime.

I had a 2006 Core2Duo 15" MacBookPro before and the screen on that became dim. Did the 2006 MBPs have CCFL backlights??

Yes.

LED backlights weren't until the 2007/Santa Rosa MacBook Pro line (with a couple exceptions: the 2008 17" MacBook Pro came with LED backlighting only if you ordered the 1920x1080 screen upgrade; the lower-resolution 17" screens still used CCFL, both in 2007 and 2008.)

In the MacBook (non-Pro) line, only the very last plastic MacBook, along with the Aluminum MacBook came with LED backlights.

For the iMac, it wasn't until the 2009 model that LED backlighting was used. (And then only on the 27", the 21.5" model didn't get LED until the 2010 model.)

The MacBook Air had LEDs from the initial model.

Late 2009 you mean. There is Early 2009 and Late 2009 iMacs and they both are substantially different. I have an Early 2009 20" iMac and it uses CCFL. For some reason the iMac screen seems to hurt my eyes a little... and the color seems kind of dirty. I think this is because of the CCFL but I'm not sure...

D-oh! Forgot that was a "two-model year", yes, late '09.
