No display, onboard or external
2006 A1181 MacBook 2.0 GHz Core Duo MacBook.
Same issue as Cort. Touch the Power Button, the screen flashes immediately for a split second and goes out. Then I can hear the hard drive and SuperDirves being accessed, but that’s it. Hold the Power Button and it shuts down. However, I cannot get the screen to even flicker nor do I have a signal for an external screen.
6 months ago, after the Cover was closed too firmly it would no longer start. It was diagnosed with a bad Logic Board and was quoted $400 - $700 for repair so we bought a new MacBookPro (with Lion). Then I went to the Apple store where they sent it to the Depot where the Logic Board, SuperDrive, Battery and other parts were replaced for only $280. When I picked it up, the Apple store guy told me how to restore files from the MBP's TimeMachine backup. That caused major software issues because the MBP was running Lion and some Lion system files migrated to the Snow Leopard MacBook.
Last week, the cursor froze 3 or 4 times a day requiring a restart. The last time, it didn't restart. I disassembled the Top Case to retrieve the CD so I could use a startup CD only to find the CD inside was an Apple Care Hardware Test that includes a startup system.
The Cable between the Track Pad and the Top Case Cable sticks out a little further than it should, but that's all I could see. I do not have the equipment or expertise to try to power up by using the above mentioned power tabs (the ones on this computer are tiny). What else should I look for? The Apple Store says this MacBook is now "vintage" and they no longer offer repairs. I called Apple to say it took more than 3 months to resolve the software issue they caused so I felt my 90 day repair warranty didn't start until my last call with them in January 2012. They disagreed. What next?
BTW, there appears to be a grounding spring on the Logic Board that contacts the bottom of the Keyboard. Can the computer be started as suggested above without this making contact?
