Hello Guys,

I am using ULN2803 to drive some segment but it is seen that most of the time some outputs of that pins got damage.
These Seg-A1 to Seg-H line are going parallel for internal display and for connector on which we can connect multiple segment PCB's.
I have attached the ckt diagram please give some advice.

Your informations invite for guessing.

"Not 200 Ohm" tells us nothing.
* they might be 201 Ohms or 199..
* or 1000 ohms
* or 1 Ohm
* or no resistor at all, maybe a capacitor?
* ...

Why don´t you clearly communicate "what they are"?
