We have e a 2007 Open Road TSA 35 and had the same problem. My jacks would intermittently "fail," but I was able to get the system activated by pressing the the ON button for up to 30 seconds, sometime more. Fortunately, I've always gotten to jacks down and, more importantly, up. I spoke to "Sue" at the company who mentioned they were aware of the problem. She indicated there is a newer control panel that is made for the newer system, but didn't know if it would work on the older systems. Unfortunately, she is no longer there.
