"Is replacing the backlight possible?"に関する回答I replaced the CCFLs in my display. I don’t recall which I ordered from but Plazmo.com and CCFLwarehouse.com have the CCFLs to replace the ones in your monitor. After the replacement my monitor was slightly brighter but it illuminated another problem, which is that the display is turning pink as it ages. Next thing I might try is replacing the entire LCD panel with an LED version, just to keep the nice bezel and aesthetic of the cinema display, but that’s a project for another day.
"Can the graphics card of the 24" iMac be upgraded?"に関する回答Has anyone considered the possibility of using Nvidia drivers from one of the OSX86 projects to make some of these cards work without flashing the BIOS with EFI? The list of compatible cards is here: http://www.tonymacx86.com/wiki/index.php... In my mind the process would be to first install the necessary kexts (kernel extensions) for the Nvidia support, and then perform surgery on your iMac to install the new card (an MXM HE card, of course). I have an iMac 24" Early 2008 with an Nvidia 8800gs and I am considering trying this to allow me to install a card with more RAM so that I can run GPU-enabled Adobe apps such as Premiere which require at least 768mb RAM.
