Running disassembled, to check replaced inverter
I have followed all 46 steps to replace the inverter in my MacBook 2006 A1181.
Now I have it taken apart and have my cheap replacement inverter swapped-in plus a replacement fan - both 2nd hand on ebay (I wasn't sure whether the "new" parts on ebay were genuine, having been burnt by "compatible" macbook batteries before).
Before I reverse all 46 tricky steps, I'd like to test it in a disassembled state. Perhaps I also need an inverter cable (backlight unreliable), or perhaps the replacement inverter board is also no good.
I've tried reconnecting all cables I think prudent (missing out only the dvd+battery). And I've tried screwing a couple of the hinge screws back in in case there's an earth connection needed here.
But in both cases I get a blank screen after the startup sound. And I'm pretty sure there's no data coming through - I can't see a faint image on-screen like I could when it was disassembled.
Perhaps it thinks the display is closed. But I can't see any contact switches.
Do I really need to reassemble everything, or is there something likely wrong?
Is this a good question?
