Yes, every light in the entire coach failed, and in my case, it was quickly diagnosed as there being a massive leak that was channeling rain water into the space behind the wall directly behind the co-pilot seat. Instructed to pull the multiplex panels (3 of them) off the wall and dry them out. Also instructed to put my fingers through the holes in the wall and see if I could feel wetness. Easy to feel wetness because everything was sopping wet. Also, the back of the matrix panels were wet and eventually the water shorted out individual LED lights in the panels and the entire panels stopped working also (they were burnt up by shorts).
At an early stage in this problem, it was suggested that I pull the panels out of the wall far enough that I could get to the 2 wire plastic connectors which tether the panels to the coach wiring. Then, use a hair drier to dry off all the plastic connectors and the back of the panels themselves. That solved the problem temporarily. However, it continued to rain heavily for another 24 hours and the whole thing shorted out for the last time again, and every LED light on the coach was made inoperable. I then decided to make an emergency trip to Middlebury, where they kept the coach 2 weeks and during that time, ripped out the "sheetrock" and all the wood panels up above the seat and over the front dash. They have a rain room in Middlebury and the coach was put into the rain room twice. The first problem was a "void" found between the front cap and the body of the coach, and that was filled. But it still was taking on water so back to the rain room and then they found that one of the support brackets for the front Girard awning had somehow worked loose and there was no seal, so that was re-sealed.
You might be able to profit from my story. Getting behind the panel to dry things out will probably help you. However, you need to get this fixed pronto as the possibility of black mold and mildew is a serious one. To Entegra's credit, I did not need to beat them over the head about my concern with this issue...... they brought it up first and I believe they did everything that needed to be done at the time to get the leaks found and stopped. I have no idea of what they used to stop the leaks or whether it has been permanently fixed, but that is the story.
