    Does anybody know what the specs of the LED transmitter are? Would an OP290 series diode work?

    Here is a link to it: http://www.mouser.com/ds/2/414/OP295A-183177.pdf

    Any help would be much appreciated!

    I had 1 LED that was bad and when I replaced it the new one went bad. The resistors seem fine though. I think 2 other LEDs are bad though, but I just cant figure out what would be causing that.

    I'd love to just fix the one I have before ordering the replacement board!
