2007 iMac 24" black screen works for 2 months then black for 2 months?
So my 2007 iMac 24” has the black screen issue, but not the typical issue where you can see the display if you put a flashlight to it.
It goes black then I try the pram reset, then try to boot another 10 times then put it in the garage to collect dust for a couple of months. It does make the normal spin noise from the cd/dvd on boot and it does chime. After a couple of months if I plug it back in and boot it, it works.
Then a month or so goes by and when I boot it, it is black screen again. It should be noted the #4 LED is off when it goes through its couple of months of being black.
And on when it works. I’m not sure if moving it around after a couple of months has made a bad connection reconnect or if maybe the temperature in the garage either makes some faulty connectors expand or retract and then it works again.
Any ideas? I’m thinking its a loose connector or a faulty connector somewhere, but this process always repeats, its reliable for a month or so, then black for a couple months, then works again.
Rinse and repeat …
I know some people will say its a bad LCD, or bad inverter, or bad I/O board, or a bad logic board, but if I show it to someone while its going through its phase of working and ask whats wrong with it?
The answer would be nothing, it looks like everything is working fine.

Nothing like paying $70 for a logic board to end up with the same problem.
