Screen have no backlight? Replace the inverter.

  1. MacBook Core Duo Inverter Replacement, Battery: step 1, image 1 of 1
    • Use a coin or spudger to rotate the battery-locking screw 90 degrees clockwise.

  2. MacBook Core Duo Inverter Replacement: step 2, image 1 of 1
    • Lift the battery out of the computer.

  3. MacBook Core Duo Inverter Replacement, Memory Cover: step 3, image 1 of 1
    • Remove the three evenly-spaced Phillips screws from along the rear wall of the battery compartment.

    • The screws are captive to the metal memory cover.

    • When replacing the battery casing, use a spudger to re-insert the foam cushioning behind the rear wall for propper battery spacing.

  4. MacBook Core Duo Inverter Replacement: step 4, image 1 of 1
    • Lift up on L-shaped memory cover, slide it to the right, and lift it out of the computer.

  5. MacBook Core Duo Inverter Replacement, Upper Case: step 5, image 1 of 1
    • Remove the following 3 screws:

    • One 11 mm Phillips #00 in the middle of the case.

    • Two 14.5 mm Phillips #00.

    • If the screws stick in the case, you can use a magnetized screwdriver to draw them out.

    • The shorter of the three screws goes in the middle.

  6. MacBook Core Duo Inverter Replacement: step 6, image 1 of 1
    • Remove the following 3 screws from the rear wall of the battery compartment:

    • Two 3 mm Phillips #00. (A1181 has three 3 mm screws and one 4 mm.)

    • One 4 mm Phillips #00 on the right side.

    • When reinstalling these screws, press gently on the lower case to line up the screw holes.

    • These screws easily strip, so be careful while taking these particular screws out.

  7. MacBook Core Duo Inverter Replacement: step 7, image 1 of 1
    • Remove the two 6 mm Phillips #00 screws from either side of the right wall of the battery compartment (not the ones closest to the battery connector).

  8. MacBook Core Duo Inverter Replacement: step 8, image 1 of 1
    • Remove the four 3 mm indicated Phillips #00 screws from the front wall of the battery compartment. When working from the left, remove the 2nd, 4th, 7th and 9th screw.

  9. MacBook Core Duo Inverter Replacement: step 9, image 1 of 1
    • Remove the following 4 screws from the back of the computer:

    • Two 7 mm shouldered Phillips on the far sides.

    • Two 10.5 mm Phillips toward the center.

    • Do not over-tighten these; you can cause the case to distort.

  10. MacBook Core Duo Inverter Replacement: step 10, image 1 of 1
    • Remove the two 5.2 mm shouldered Phillips #00 screws from the optical side of the computer.

    • It is not necessary to remove the similar screws on the other side of the computer.

  11. MacBook Core Duo Inverter Replacement: step 11, image 1 of 1
    • Starting near the display and working around to the front of the computer, pry up on the upper case. It is held with clips on the right above the optical drive. These will release with some firm lifting pressure.

    • Be careful when prying up the upper case. It's very easy to slice open a fingertip and thus provide the blood sacrifice the Mac gods sometimes require of those who insist on doing their own repairs.

    • There's a trackpad and keyboard ribbon connecting the upper case to the logic board, so don't pull the upper case off entirely just yet.

    • If you have trouble getting the clips to release, be careful that you are not prying the plastic top of the upper case away from its metal frame.

  12. MacBook Core Duo Inverter Replacement: step 12, image 1 of 1
    • While holding up the upper case (from the bottom or the top), use a spudger to pry up the orange trackpad and keyboard cable from its connector.

    • Take care to pry between the black socket and the white connector. You might have to pry on both sides for it to release properly.

    • Do not pry from the bottom or the top, but from the sides.

    • If you happen to break your upper case cable when removing the upper case, we stock the cable individually and we have a guide that makes replacing it easy.

  13. MacBook Core Duo Inverter Replacement, Optical Drive: step 13, image 1 of 1
    • Grasp the white plastic tab attached to the hard drive and pull it to the left, removing the hard drive from the computer.

  14. MacBook Core Duo Inverter Replacement: step 14, image 1 of 1
    • Remove the two Phillips screws from the front edge of the optical drive.

    • The shorter screw (3 mm) is recessed nearest the RAM modules. The other is 3.5 mm.

  15. MacBook Core Duo Inverter Replacement: step 15, image 1 of 1
    • Disconnect the orange optical drive ribbon cable from the logic board.

  16. MacBook Core Duo Inverter Replacement: step 16, image 1 of 1
    • Disconnect the newly-revealed display data cable. If there is no pull-tab on the top of the connector, it may be helpful to use a spudger to disconnect this connector.

  17. MacBook Core Duo Inverter Replacement: step 17, image 1 of 1
    • Disconnect the (once again) newly-revealed hard drive cable.

  18. MacBook Core Duo Inverter Replacement: step 18, image 1 of 1
    • Peel up the foil tape between the fan and the optical drive.

    • Remove the 8.5 mm Phillips screw securing the display data cable to the metal framework.

  19. MacBook Core Duo Inverter Replacement: step 19, image 1 of 1
    • Pull up the display data cable from along the edge of the optical drive to reveal a silver Phillips screw.

  20. MacBook Core Duo Inverter Replacement: step 20, image 1 of 1
    • Remove the 2.8 mm Phillips screw securing the optical drive.

    • The Bluetooth cable may be covering the screw; carefully push it aside before removing the screw.

    • Do not over-tighten this screw when re-mounting. You could break the plastic enclosure.

    • After removing the screw, push the metal tab backwards, towards the fan, to release the front of the optical drive.

  21. MacBook Core Duo Inverter Replacement: step 21, image 1 of 1
    • Lift the Bluetooth antenna board from the right side of the optical drive.

    • Deroute the hard drive cable from along the front of the optical drive.

  22. MacBook Core Duo Inverter Replacement: step 23, image 1 of 1
    • Lift the front edge of the optical drive and slide it up and out of the computer.

  23. MacBook Core Duo Inverter Replacement, C-Channel: step 24, image 1 of 1
    • Remove the following 3 screws:

    • Two 3 mm Phillips near the right speaker.

    • One 6 mm Phillips threaded through a hole in a plastic finger above the subwoofer.

    • Be careful not to over-tighten the screw above the subwoofer too tight or the plastic could crack.

  24. MacBook Core Duo Inverter Replacement: step 25, image 1 of 1
    • Lift the right speaker out of its housing and set it to the side.

  25. MacBook Core Duo Inverter Replacement: step 26, image 1 of 1
    • Using a spudger, gently pry up the white plastic slot and slide the metal c-channel to the right and away from the display.

  26. MacBook Core Duo Inverter Replacement, Display: step 27, image 1 of 1
    • Use a spudger to carefully disconnect the microphone cable from the logic board. You'll want to work from side to side, and slowly wiggle the connector out of its socket.

    • Pulling on this connector vertically will break the socket off the logic board. This connector should be removed horizontally by gently pulling the microphone cable toward the screen while working a spudger between the connector and the socket.

  27. MacBook Core Duo Inverter Replacement: step 28, image 1 of 1
    • Lift up on the black right speaker cable with one hand, and deroute the silver microphone cable from the silver metal clip just above the right RAM slot.

  28. MacBook Core Duo Inverter Replacement: step 29, image 1 of 1
    • Deroute the silver microphone cable and gray display data cable from the tabs at the bottom of the subwoofer.

  29. MacBook Core Duo Inverter Replacement: step 30, image 1 of 1
    • Remove the single 3.2 mm Phillips screw securing the ground loop in the display data cable located just above the Bluetooth board.

  30. MacBook Core Duo Inverter Replacement: step 31, image 1 of 1
    • Disconnect the two antenna cables from the Airport card, and the black inverter cable from the logic board. (Pull vertically on all three.)

  31. MacBook Core Duo Inverter Replacement: step 32, image 1 of 1
    • Remove the following 2 screws from the right hinge mount:

    • One 6 mm Phillips on the left side of the hinge mount.

    • One 10 mm Phillips on the right side of the hinge mount.

    • Lift the right hinge mount out of the computer.

  32. MacBook Core Duo Inverter Replacement: step 33, image 1 of 1
    • Hold the display with one hand while removing the screws from the left hinge mount.

    • Remove the following 3 screws from the left hinge mount:

    • One 6 mm smaller diameter Phillips from the right side.

    • One 6 mm larger diameter Phillips from the middle.

    • One 10 mm Phillips from the left side.

    • Lift the left hinge mount out of the computer.

  33. MacBook Core Duo Inverter Replacement: step 34, image 1 of 1
    • Grasp the display assembly on either side, and lift it up and out of the computer.

  34. MacBook Core Duo Inverter Replacement, Front Display Bezel: step 35, image 1 of 1
    • The following steps should be identical for both white and black MacBooks.

    • Use a thin plastic card to release the tabs and their clips holding the front display bezel to the display assembly. There are five tabs along the left side of the display bezel.

    • You may find some display bezels are easier to remove if you work from their inside edges, directly adjacent to/above the LCD panel.

    • Don't use a card that cannot be replaced if damaged. The clips can be difficult to remove and the card can bend and break, rendering it useless.

  35. MacBook Core Duo Inverter Replacement: step 36, image 1 of 1
    • Continue to free the tabs along the the top edge of the display assembly.

    • Be careful when working near the iSight camera.

  36. MacBook Core Duo Inverter Replacement: step 37, image 1 of 1
    • Next, free the five tabs securing the display bezel on the right side.

  37. MacBook Core Duo Inverter Replacement: step 38, image 1 of 2 MacBook Core Duo Inverter Replacement: step 38, image 2 of 2
    • Lift up the front display bezel from the top and use your plastic card to free the tabs along the bottom edge of the display bezel.

    • Make sure that your card is between the metal frame around the LCD panel and the display bezel and not touching the LCD panel itself.

    • After freeing all holding tabs, lift the front display bezel away from the display assembly.

    • When reinstalling the front display bezel onto the display housing, you may find it easier to get the tabs and clips to connect if you push on the four sides of the bezel in this order: top, bottom, then the sides (left or right). You may have to apply extra pressure along the bottom side of the bezel to get it to snap into place firmly.

  38. MacBook Core Duo Inverter Replacement: step 39, image 1 of 2 MacBook Core Duo Inverter Replacement: step 39, image 2 of 2
    • Sometimes when removing the front display bezel, the retaining clips that should remain captive in the LCD brackets come out with the front display bezel. Follow this and the next step to transfer the clips back to the LCD bracket.

    • Use a metal spudger or another thin tool to carefully pry the gray plastic clips off the tabs molded into the front display bezel. A 0.8mm flat screwdriver may be useful for this step. You may find that it's easier to remove some of these clips by prying up on their long sides.

    • Be careful, as the clips are made of thin plastic and are inherently delicate.

  39. MacBook Core Duo Inverter Replacement: step 40, image 1 of 2 MacBook Core Duo Inverter Replacement: step 40, image 2 of 2
    • Insert one end of the retaining clip beneath the edge of its recess cut into the LCD bracket.

    • Use the edge of a spudger to push the short hook tab on the underside of the other end of the retaining clip into the recess cut into the LCD bracket.

    • The second picture shows a retaining clip properly installed.

    • You may find it easier to get the short hook tabs on the underside of each end of the clip to fit down inside their cutout in the LCD bracket by first very slightly bending down the two ends of the clip, but be careful not to bend the clips too much--only a slight bend is needed, and too much force will break them.

  40. MacBook Core Duo Inverter Replacement, Clutch Cover: step 41, image 1 of 1
    • Remove the three 4.2 mm Phillips screws securing the clutch cover.

  41. MacBook Core Duo Inverter Replacement: step 42, image 1 of 1
    • While holding the display down with one hand, use your other hand to lift the left end of the clutch cover off the clutch hinge and guide the inverter cable and AirPort cables through the gap in the clutch cover. If the cables snag on the two hooked tabs on the inside end of the clutch cover, free them carefully.

    • It may help to wiggle the clutch cover as you pull it up from the display.

    • During reassembly, make sure not to pinch the black inverter cable or the Airport wires when snapping the left end of the clutch cover back into place. To avoid pinching, it may help to lift up and hold these cables and wires in place at the top of the hinge, rather than leaving them running along the sides of the hinge.

  42. MacBook Core Duo Inverter Replacement: step 43, image 1 of 2 MacBook Core Duo Inverter Replacement: step 43, image 2 of 2
    • Lift up the right end of the clutch cover while guiding the display data and iSight cables through the gap and the two hooked tabs at the right end of the clutch cover. If the cables snag on the two hooked tabs, free them carefully.

    • Lift the clutch cover off of the display assembly.

    • During reassembly, avoid pinching the display data and iSight cables. While guiding the right end of the clutch cover into place, but before snapping it down, guide these cables between the two hooked tabs inside the right end of the clutch cover, and up into the curved area of the clutch cover, above the hinge.

    • Also avoid pinching the backlight wires (with the white connector on the end, plugged into the right end of the inverter). They should run under the upper right edge of the clutch cover. In some models, the two wires are gray and black, and in others they're white and pink. They lead into a hole in the lower right edge of the LCD to the backlight.

  43. MacBook Core Duo Inverter Replacement, Inverter: step 44, image 1 of 2 MacBook Core Duo Inverter Replacement, Inverter: step 44, image 2 of 2
    • Slightly lift the newly-revealed inverter board out of its housing and disconnect the black inverter cable from the left end of the board.

  44. MacBook Core Duo Inverter Replacement: step 45, image 1 of 2 MacBook Core Duo Inverter Replacement: step 45, image 2 of 2
    • Disconnect the white inverter cable from the right end of the inverter board.

  45. MacBook Core Duo Inverter Replacement: step 46, image 1 of 1
    • Remove the inverter board from the display.

while this is the offical way to replace an inverter, those of us at the repair depot quickly learned a much faster why that only involves removing the display bezel and clutch cover.

remove display bezel like normal.

remove the 3 screwa from the clutch cover.

pry lose the clutch cover while the lid is open and then some more when it is closed to get it to pop off.

replace inverter and then carefully replace the clutch cover in the reverse of before.

you may need to clip off the top parts of the tabs inside the clutch cover to get it to replace easier, these serve no purpose and can be safely snipped if needed

we had a few thousand macbooks on hold because we had ran out of stock on the inverters that we were forced to come up with this method to get them all repaired in 1 day when the shippment of inverters finally came in after 2 months of being out of stock. this turned a 30-45 minute fix(including our documentation) into a 5-10 minute fix
