Hi All,
I'm having trouble repiaring a PCB which contains an LCD temperature display board. It looks like there is a resistor missing from the board.
The device is a generic non-branded device (vaporizer). I tried to find the make / model by matching it up on google images, but no luck.
The part number on the LCD unit itself is ZYH-E30561-IF
The part number on the MC is EM78P259NS018J
I can't find a good datasheet for it.
I was hoping to find a whole new LCD / MC assembly, but I'm having trouble with just the standalone components.
The resistor on pin 16 is missing (R5). I can't think of when it could have come off, but there is solder on the board suggesting that something was in-fact there.
I thought of hooking up a potentiometer and using trial and error, but I wouldn't know what to test for.
Any ideas?
Obviously I should just buy a new vaporizer at this point, but this is more of a learning exercise for me.
