here's a pic of my diode work
hmm smd should work.. unless you have the polarity reversed. line should be pointed towards the cathode (-)
I only went with through hole cause it was easier for me
maybe post a pic of your pcb with the diodes so we can see what might be wrong?
sorry for the potato pic haha, never got around to cleaning the flux off the pcb.. and case is getting dirty
if you need a closer shot, lemme know
