[CA] [CA11] 4K open array not working with E120

[rob minks]

I was helping a customer replace an older e-120 with an older but new E120. He also wanted to change the open array with a used one that wasn't discolored and relocate the array and motor. I unbolted the array, lifted it off and replaced it with the other unit also pulling the 8 pin plug, + and - wires. All power was off throughout the process, the plug was wired back up to spec. Power was turned on and every thing worked except the screen only displayed about 1/8 mile after any adjustment I was familiar with. I put the original array back on and the problem remained. He says everything worked fine with the old E120 and array and I must have damaged the radar. Is that even possible when carefully replacing the open array and plug?
