I have a new-ish (but old enough to be out of warranty) PAL PCR-4 running 1 under water light and 1 light bar on a water feature. Went to turn on the lights for the first time in a couple months and nothing. I pulled the cover on the driver box and the red power light indicates the system is getting power. It's a 2 year old pool fiberglass pool so I am doubtful water has gotten into the underwater light although it's possible I'm sure. Anyone have tips for troubleshooting and what to check next? The only changes to the system is I powered everything off to replace a water temp sensor that I had cut with the weedeater but like I said, checked the power light inside the driver box to make sure I didn't accidently knock something loose while I had the cover off the panel attaching the new sensor. Any help would be appreciated. Thanks.
