In a Philips CDR755, year 2000. Working fine previous time of use and then nothing at the next use. Turned out to be a 1N5406 size package SB360 3amp 60V shottky diode gone short circuit on the LV side for the
5V rail. No other colateral damage (not tried recording a CD yet but both decks play) , maybe a very slight discolouration on the anode end of the diode, could equally be from time of encapsulation. After the Tx , I would have said probability-wise. about the least likely item to fail. Original manufacturing flaw that progressed or something to check for before being certain just an isolated failure? if there was ,say, a power surge/spikes or something could that cause a failure to that diode and nothing else? Was it just coincidence there was a water leak , over electrical equipment elsewhere in the house about the time of this failure.- posted
