[QUOTE="chscag, post: 1854463, member: 46727"] Welcome to our forums: Model and year of the iMac? If you can't find that info, jot down the serial number and go to the following site and enter the number: [url=https://everymac.com/ultimate-mac-lookup/]Lookup Mac Specs By Serial Number, Order, Model & EMC Number, Model ID @ EveryMac.com[/url] The reason we need the year and model of the iMac is so we can determine if the backlight is the older type or the newer LED type. Also, there is a fuse on the logic board of some iMacs that protect the backlight. You may be able to find it by going to: [url=http://www.ifixit.com]iFixit: The Free Repair Manual[/url] You might also be able to get help from that site to troubleshoot the backlight problem. On the older Mac computers which used a fluorescent backlight, the backlight is encased within the display assembly itself. Apple recommends changing the entire display rather than just the backlight. Good luck with the repair. [/QUOTE]
