diode blown up
(1/1)

Hello dear community,

i have a question about a repair attend.
i have bought a LCD display for a tablet. i installed it and during charging i accidentally pulled the LCD ribbon cable out and a SMD started to smoke.
there are 2 diodes on pic. both are shorted (diode test) and one of them is even blown up.
The question is, can i solder any small diode as replacement or it must be a SMD and with very specified values for a diode?

Lables: S4 and 4P
S4 is blown up


Thanks in advance :)
gamalot:
S4 is 1N5819 or SS14 Schottky diode.

4P is MM1Z5V6 Zener diode.
