Chances will be slim but trying anyway:
Just bought an LCD display from my regular HW dealer. It came with the pins separate so I had to solder them on the circuit board of the display.
I think I did a good job (see pic) , checked bottom and top of the pins with multimeter and they are all ok.
According to the specs (https://www.display-elektronik.de/filter/DEM20231SYH-PY.pdf ) and based on the jumper settings (J2,J3,J4,J5) I should have PIN 16 as +5V (anode) and PIN 15 as ground (cathode).
At first I swapped them because I based myself on the starter kit version but not for long, AND it should normally be equiped with some light diodes to avoid damage, right? or at least not get damaged because of it… (it was only a minute or two before I noticed it).
I had everything connected (invl V0 via pot, RS, E, R/S to ground, VSS/VDD also connected) but the display stays dark.
Is there any other tests I can do to confirm it’s dead?
