I'm thinking I may have 4 bad opto's, but what are the odds of that? The low voltage side of the opto's all have the same level. The output side has 110v on pins 4&5, as you would expect, but only on the lit LED's. The ones not working have near 0V on pin 4 and 110v on pin 5.

So do all of the channel leds turn on in the test mode?
Yes this is my question also. If the leds for a channel are lighting the pic is doing its thing. The same current that turns the Led on also turns the opto on. If the leds do not light #1 to check is backwards led on that channel. Then the pic might be changed. Simple design so it will have a simple answer.
Catch me on teamspeak and we can walk through a complete test in a few minutes that will tell you exactly what is wrong.

BTW it might be the light fooling me but it looks like you have at least two of the 180 resistors on the bottom leg that look like they are unsoldered? check and make sure this is not correct.
I sure hate when life gets in the way of my hobby's
I had to bail on the troubleshooting for a couple of days, cause of work obligations and yard work
Now that the lawn is mowed, fertilized, and looking good... I'll recap what I have tried.
1. Resoldered all joints in question from 330ohm resistor to terminal header.
1a. Verified all LED's are oriented correctly.
2. Replaced the 4 opto's with new.
3. Swapped the Pic with Pic from LE #1.
LED's #2,13,14,15 do not light up, nor does mini lights on these ch's.
Going to look over solder joints in the sunlight today. Hopefully I've missed something in the dark, dingy light of my cave.
