Will not power up, checked adapter and battery
After servicing a wonky screen cable properly and not fiddling with what I shouldn't be (I have done this before) my PB suddenly will not power up. Yes, a different adapter was tried. Yes, the RAM cards are in properly. Yes, the PRAM is okay. All indicators seem to point to an inexplicable DC Input failure. Yes the logic board my have suffered some inexplicable urge to suddenly fail. But the adapter input does not light, tests were preformed with and without battery in, I even plugged a Flash Drive with an indicator light on it into the USB that is part of the DC Input board, and it didn't indicate power.
The adaptor plug will flash a rapid amber if there is slight pressure applied. Also there is a faint clicking noise in that region when it's plugged in.
Is this a good question?
