If you have a DMM with a diode check feature, just probe the LED terminals. When you have the positive lead on the anode the DMM will indicate a forward biased diode junction and the LED will light up!
It won't work with modern DMMs in "ohms" scale because they limit the current too much to avoid damaging parts, but "diode check" works FB.

The LED chip replacing R101 has two little green dots on it. Can someone give me the orientation of this chip. I don't know which side is the cathode.
