Chosen Solution
Mid 2007 machine: I broke my LCD display and found a replacement off ebay. It came with the wiring harness, inverter and all the metal brackets for $100. I was nervous because this seemed to good to be true for $100. I changed it out step for step from the repair section and got nothing. So I ordered another LCD, and inverter from here. Did everything step by step again with no luck. I tried one more inverter and now I can see the display if I put it at an angle but there is no light at all. I have no idea were to go from here. Everything else works fine on it because I am using it on an external monitor, but that defeats the purpose of having a laptop. Any ideas would be greatly appreciated! This is the model info off the backside of the kepad: A1181 (Mid 2007) Black/2.16/2x1G/200/SD/AP/BT
Could be a broken backlight bulb, the inverter cable or the inverter board that may be bad. I worked on machines (mostly iBooks G4) that had been dropped with broken hinges and the inverter cable shorted in the hinge blowing a microfuse that protects the inverter circuitry on the logic board so if all other lightning components are in working condition then the microfuse can be the culprit.
Try running the Apple Hardware Test, I have a feeling more than just the LCD could be damaged.
rab777hp Is that the disks that came with it?
Hi I had the same problems with my display; changed inverters and installed a brand new LCD. Display was also still visible on an external monitor… I ended up stripping the logicboard of the heatsink+fan, wifi card and battery pack before placing it in my dishwasher (by itself, with NO detergent) at 70 degrees for the full cycle. This process steam-cleaned the logicboard for me (kinda like they when manufacture the logicboards). I left it overnight to dry; used a hair drier the following day to make doubly sure the logicboard was fully dried. I refitted the battery pack, fan+heatsink, wifi card and all loose cables. I then used IsopropoI Alcohol to clean any remaining thermal paste off the heatsink and processors before using nano-diamond thermal paste (PC World) to stick the heatsinks and processors together again (as they were originally). Having put the case back together and powered up, I now write this to you from a fully functioning Mid 2007 Macbook complete with working screen. This process even managed to fix my trackpad button and Superdrive, both of which had stopped working over a year ago!!! Hope this helps…
