I have been handed a Powerbook 170 to have a look at it.
The Powerbook was not powering up and obviously the PSU connector was shorted (my replacement PSU included a LED, and this was flickering when connected)
Under the Logic Board, a diode was shorted (D16) but it was impossible to find a label on it.
Fortunately, Ferrix97 posted a video with this same problem, giving a valid substitute (1N4007)... the Powerbook booted right away.
probably someone used a power brick with inverted polarity at some point.
