I am in need of some information and help. I have a MotoSat MD500 with Nomad 2 controlling dishnetwork. I have had it since 2006 and has worked great everytime we get someplace just push the button and everything works. EXCEPT yesterday, I haven't used the motorhome in about 10 months this year, went out of town and set up, push the button and the dish would not lock on the satellite. I read the troubleshooting in the manual and i am not having any of the flashing light problems it is discribing. I watched the lights as the dish rotated, I received the DVB light but would not lock. I have had nothing done to the system since 2006, I have been reading other forums and there was mention of upgrade, but all of those posting were back in 2008 and I have used it since then. Can someone please help.
