water master 57116

I am new to this site and it seems really informative and can't wait to read a ton of threads, but in the meantime maybe someone can help me out here. I have a 3 zone irrigation sprinkler system that was installed maybe 15 years at my fathers house, where i recently moved in after my mother's death. I went to turn it on for the season and the wires we're pulled out from the control box in our basement. the unit is a water master 57116, there is a red, green, blue and white wire, along with 2 power wires plugged into the wall. the white and red wires were out and i replaced them with the white in the com slot, the other 3 wires are in zones 1-3. the unit is easy enough to program, but i cannot get the sprinklers to come up or the system to start. i was playing around with it today at 2:00 pm and set it to go on at 2:10 pm and waited, 2:10 came the unit flashed 25 minutes(the duration i set it to) and i went outside to see and NOTHING! i am lost here, someone please help! i checked outside in the underground box and everything seems fine, all wires are connected and whatnot, the water is on and the system was working last year.

all fixed

sorry for answering my own question, but as i said i was new to this stuff. there is a valve next to my water spigot outside with a valve on it with bleed screws, this was off and the bleed screws were open from someone flushing the system last year, i closed the screws, opened the valve and voila! I had sprinklers! only 2 of the 3 zones is working though, i tried all differant combos, but still only 2 zones, is there a solenoid outside in the underground box or something? i have 2 front yards and a side yard, the side yard is'nt visible anyways, so i used the 2 working zones for the 2 front yards and can live without a side yard sprinkler for a while.
