You have an electrical issue. Usually the problem is in the print head cables and/or longer cables that go back to the head boards. Check all of the connections to make sure something didn't pop out or ink got into the terminals. You could try changing the cables to be sure. Other than that, if the cables are good, your head boards could be damaged or the head itself. I'm not sure on the JV5 but the Mutoh muli-head machines have an option in the RIP, under printer settings usually, that allows you to print using only specific heads. Take a look around your software for a similar option.
