After a few solid years of use, the Header II on this motherboard has decided to put out the Green RGB signal regardless of the setting. This happens with multiple fans and cables, so clearly is a board level problem. What it means is that green works, and all other colors end up incorrect with the Green turned up to 255. Calibration etc, does nothing as the green signal won't turn off even if set to zero. Has anyone else had this issue and found a solution? Is the mobo itself "broken" in some sense? Thanks.
