If all voltage test points are within range, then it's 1 of 3 problems: Power Conversion Plug is faulty; Power Control Board is faulty; or Controller is faulty. Jandy says there is no way to test any of these directly. They recommend that you replace both the Power Conversion Plug (~$35) and the Power Control Board (~$230). Apparently when one fails, it can cause the other to fail as well. They said that unless the Controller has a lot of corrosion on it, then it probably is not the issue.

SOURCE: I have a Jandy Aqualink
On the RS system there is a small fuse on the back of the circuit board. That may have been burnt. It acts as a safety for the transformer. Make sure ALL of the power is off, then check that fuse. Do not keep the shorted valve actuator plugged in. Replace it, or leave it disconnected. Then replace the fuse. Then re-apply power to the unit. Otherwise your transformer may go out next. If the fuse is not burnt, which would surprise me, you may have a burnt transformer.
