I have a diode to replace on a computer disk drive. I had just removed the pcb to allpw access to clean out the masses of dust build up and general cleaning and read errors.
When i put the pcb back in and powered it up I got a feint burning smell and pulled the power. After removing it again I noticed one of the wires (red) on the power connector had come out (badly crimped) and I dont know what happened but it was the only thing I could see that could have caused this (maybe it touched something).
Anyway I could only see signs of a track getting hot and a diode discoloured. It connets to CN4 power input 12v or 5v.
I dont know if any other damage is done but I must replace this diode now but I am not sure what type this is. It looks like a zener but knowing how many there like a avalanche etc can someone tell me please? and any advice would be welcome.
