MacBook no ram no beep, black screen, no chime, solid sleep light
I got a MacBook of 2007, but it doesn't boot, the screen stays black, the sleep light stays white (no blinking) and there is no chime. I can here the hard drive working.
USB port are working. I can't test it with an external monitor but I think it won't work.
I removed the RAM but I didn't get the beep that would tell me a problem with it. Reset of PRAM and SMC didn't change anything, neither testing with one empty slot.
There is a lot of similar problems but none of the solution worked.
As anyone an idea of the nature of the problem ? And a solution to fixed it ?
