Daylight PWM port not working

So I've been running my lights on PWM for about a month now and just noticed that my Daylight PWM port isn't working. Actinic works fine and I switched the control cables and the day driver dims fine on the ACT port just fine, so it must be the port and not the driver.
Any suggestions on how to test the port or perhaps fix it?
Mine is a RA from Jan 2012.

Test the dimming port with the controllertester code in the examples folder.

You will have to send back the relay box for repair.

No way I can do the repair myself?

I think the op amp is bad.
LM358 inside the relay box.

I had a similar problem with the relay box, where the dimming channels were not working. Roberto advised that I change chip LM358P on the relay board. I did that and the dimming channels were functioning after that.

Thanks for the info guys. I haven't gotten around to replacing the amp but today it just started working again. Does this change offer any clues that it might be something else? Nothing else changed Code is the same. Cables still plugged in the same ways. It hasn't even been touched in several weeks and today everything was dimming normally again.
