Beeping then White Screen then Black Screen
My friend was cleaning his house and he decided to pass his MacBook Air (A1237) to me as it wasn't working for a while now and he did not intend to repair it.
First of all light on MagSafe didn't light up after connecting so I tought that maybe the whole issue was just with the charger. I've soldered some cables and it was as good as new.
After connecting now working charger to the Macbook I've heard beeping noise - didn't know what it meant back then so I've turned it off. After some research I tought that it's probably faulty RAM.
I've tried to turn it on day after to hear the beeping again but to my suprise the screen lit up all white and I could hear chime so I tought that maybe there is problem with the logic board/screen connection. At this point I've tried reseting and using command+option+P+R - there was some mechanical-like noise and the screen did not light up this time.
Right now I don't hear chime no more, screen is black but the computer seems to be at least partially working as its getting pretty warm after a while, on-LED is glowing white and the fan is working.
I've tried cleaning the internals with air and replacing thermal paste, but it didn't bring any change. I'm thinking about hooking it up to some external screen, but micro-DVI adapter currently seems to be extremely hard to get hands on.
I know the effort probably won't be worth it, but do any of you have any advices on what route I should take now? Thanks is advance.
Is this a good question?
