Hi all, I have a Jandy/Aqualink RS8 with a wireless one-touch unit. Everything works great except the LCD on the remote one-touch. I've been told I can replace the faulty PCB and LCD (part RO550800) but it seems impossible to find. The entire unit itself looks like $1300 at a minimum to replace. Anyone know where I can find a repair part source or assistance? Thanks in advance. Craig
