No Water To Heads

Ok so I just bought a house and only 2 of 7 zones work. When I go to the backyard green valve box, I can only manually turn on 1 of the 4 valves, the other three wont supply water to the sprinkler heads but I hear water flowing and water is comming out of the valve when i go to turn it on. Im thinking that I have a bad valve or a bad silenoid, am I on the right track?

First off, see if you have continuity to all the solenoids. Check with a VOM. They shold all be in the same area, resistance-wise. If so, make sure ALL the zones have voltage output in the 29VAC area.' You can check each valve when it's on with a small telecsoping pick-up magnet to check if it's actually fired. (You can feel the 60 cycle buzz when the magnet is lifted off the top of the solenoid when it's fired.)
Next step is water supply (are all valves/V.B.'s open. Last is diaphragms.
Being an unknowm system and the low cost of diaphragms, I'd replace them one at a time and see what happens....
Good Luck!!
