I have an alpha one leg on a 2004 trophy 2052 that I have recently purchased. It has a commander 3000 side mount control. The leg will trim down fully but wil not come back up on the up button but will come up on the trailer button. I have replaced the buttons on the control however still the same. I wouldn't have thought solenoids are faulty given the engine comes up on trailer button. Fluid levels are good.. Any suggestions please
