I'm not sure if it would power on if you don't have the fans and temperature sensors plugged in, when I test for voltage output to the logic board, I had the I/O board flex cable and power cable plugged into the logic board and one memory module, but I neve r test turning it on with just that. If you do try that, in case you didn't know and it does power on with just the logic board and io board, be sure to have the heat sink mounted from keeping the cpu+gpu from burning up. Have you tried just having the ac adapter and battery removed and holding the power button for 10 secs and remain holding the power button and then plug in the magsafe cable and continue to hold it for 10 secs and then just press the power button as normal to see if it will turn on? If not, give that a try. I know with mine, I wasn't even getting the battery to charge. If you want to test at component level, you can start by testing the 2 chip fuses on the IO board, there will be one near the magsafe connector and one on the bottom of...
Meer informatieI got some life out of the macbook now and here is some trouble shooting I did to get it to now power on: I did try resetting the SMC but didn't do any good, still didn't power on, so I decided to remove the logic board and left I/O board and look for any components with physical damage and test any fuses soldered to the left I/O, but didn't see any anything, I then test the voltages from the power cable coming from the Left I/O board to the logic board, even when the magsafe plug had the green LED I was getting .5 volts when testing all 3 gray wires being (+) and all 3 black wires being (-) on the power cable at the logic board end which didn't seem right. So, from that I looked over the I/O board and took the black like tape cover off the bottom of the I/O board and found what looks like one of chip capacitor next one of the IC's that looked burned and so I took a cap off a modem PCI card that no longer works and soldered that in replace of the burned one, and then test the voltage output from the power...

Hi there, from what you described I would say to re-seat the digitizer flex cable, it would be going in the 2 connectors in upper left (left side of the logic board) Might be just bad connection there.
