I have a Genie Boom TMZ-34/19 that at any of the controls. I purchased it from a gentlemen who told me it had a problem with the system board. I sent the board to Radwell to have fixed and received it back but there was no change. I have power at the control box where the wires come from the batteries. There is one light on in the control box which has E-Stop OK beside it. Other than that the controls at the platform and ground controls will not light up at all. I replaced the fuse switch as well as the old one was broken. Both Emergency Switches are good and the key is good. It was made in 2000. I have both blue boards, again having had the system board tested and fixed. If I could get some help diagnosing to figure out where the real problem is, I would much appreciate it. Again, with the key on the only light present is the E Stop light.
