If I understand correctly you check continuity in both directions with the DVM set on ohms and its is shorted. The other diodes show open in one direction?
Yes/No?
You probably can disconnect the diode from the board and see if the IN signal returns. I am guessing that the diode is there to eliminate spikes on the output.
I am guessing the diode goes from the IN pin to either ground or 5V?
Can you tell how the diode is in the circuit?
Hello
yes the other diodes are open only in one direction
I removed the highlighted components and there are three in short circuit a diode (SS14G) I had it at home and I replaced the other two components (see photo)
WE 79A are short-circuited but I can’t find them
I tried the controller and now the laser fires even with the connector connected that goes from the LPS to the controller but after the first shot it is always on only after the first shot
now i will try to find these components that i could not find on google i asked some shops if they had any but they have yet to answer me
Hello
I tried with the components disconnected from the board except D54 (diode A7W) and the laser works but after the first touch on the test icon of the control panel the laser is always on
Yes I have the manual but something is wrong and I want to double check tomorrow just to be sure and I will be back with updates. For now thanks for your help.
