Mimaki JV3 160SP Half printhead problem

[GregS]

I have a problem with first half of yellow printhead. It is not printing at all!
I try to change cables with black printhead and the result is that yellow is printing and first half of black is not printing.
I try to change slider board and check the cables from motherboard to slider board. The problem persist.
Can anybody help with this issue?
Greg

You have a bad transistor on the main board. You troubleshot it perfectly and the transistor is the only reason left to suspect. I have seen this happen on these machines many times. See if you can find someone to fix the board for you. I would recommend someone but the guy we used to use is a crook.
