Can anyone give me a hand in diagnosing the following: The boom cylinder stop going up "suddenly" after it was being used the machine was turned off for a couple of minutes and it stopped working. It works off the left pilot valve or joystick and it transfers the hydrophilic fluid via the green marked hose to the control valve assembly. It is not the cylinder I switch the hoses on the cylinder and it worked fine. So I'm pretty sure is not the cylinder. what should I check first. the joystick or the control valve. Everything else is working on the machine even the "down" on the same cylinder.
Would appreciate any guidance. never dealt with this control valve assembly or joystick. thanks.
