No light on my 16 channel LOR

:( Ok, I am still not getting my LED light to come on my newly solder LOR board. What could it be? I did have the Q16 and Q17 switched and we reswitched them...nothing! What else could it be? If I took a picture of the board back and front would anyone be able to guide me to what is wrong and how to fix it? I really need this board working before Friday.

Hi,

By reversing Q16 and Q17 you put 10 volts into the 5 volt logic side of the card. There is a good chance that all of the ICs (except the optoisolators) have been destroyed. Please email support@lightorama.com
