Hi I got a Macbook Air, which had both hinges broken, I powered on the laptop, and the screen worked fine, although only laying flat on the couch. https://i.imgur.com/4RHec7C.jpg I moved the screen a little, and the screen went white. After that I have not been able to get a picture from the screen. No backlight, and no picture. I have changed the hinge/LCD-cable and still no reaction from the screen. The laptop itself chimes when starting up etc. What could be the problem? I’m very, very new to the whole “micro-soldering” etc. But I want to learn it, and I’m not stupid (Not that stupid anyway). I have googled plenty, yet I’m not that great at analyzing, tracing. Basically I don’t know what I should look for. I’ve got access to both the schematics and the boardview, for easier diagnostics, but I can only locate the issue to a limited extend. I got 0 volts on pin 3/4 on the LCD connector.Voltage is fine on both sides of the (F7700) fuse. Although I only get a voltage-reading on 3,4 and 5 on Q7706 - Pretty much the rest in that entire area gives me 0 readings. https://i.imgur.com/vpOgHAv.jpg https://i.imgur.com/MYt9n1n.jpg Can someone help out a newbie? Thank you! -Andy
The broken hinges have cut and shorted the data & backlight cables. You’ll need to first disconnect the display assembly to do any trouble shooting as you’ve still got a short in the wiring. From the looks of it you’ve got a few components burnt are you upto micro-soldering? If not I think the best thing here is to bring it into an independent Mac repair shop as this is going to take some work which Apple or their authorized service centers won’t do.
