Same thing happened to me my first time—brief blue light but would not power on. Tore it down and re-connected all the cables more carefully the second time. That fixed it.
I have done this successfully three times now—thank you for the excellent guide. Newcomers should know there is one ERROR and one OMISSION in the procedure. (1) ERROR - In Step 13, the topmost ZIF connector marked in red *does* have a clamp, unlike the other four. If you attempt to pull the connector loose without opening the clamp you will break it—see the frustrated comments to Step 13 for examples. (2) OMISSION - At Step 16, before removing the cartridge drive you must unplug the connector at the top of the component. This is shown as unplugged in the photo, but the step is missing from the written instructions. The clamp on this plug loosens on the *opposite* side from where the cable is inserted, unlike the other clamps in the guide.
Agree here. I’m doing the job to replace the lower screen, and connecting these two cables at the corner was the hardest part of reassembly. I would have done the job without disconnecting these.
Missing an instruction for releasing the connector left of the top screw. The black latch to flip up is on the back (lower) side of the plug, then the connector pulls out of the front (top).
Glad I read the comments first! The topmost red connector DOES have a clamp you need to flip up to release.
