Hello Tawyxxz,

The manual override procedure will force the brightness setting of your VK204-25 back to the default value. I see you have also confirmed the unit responds to manual brightness commands.

Unfortunately, this unit may be suffering from a hardware fault. If you could please provide the serial number of the unit to me at tclark@matrixorbital.ca we can explore options for an RMA.

The serial number will be in black ink on the back of the unit in the form ##M##-####.

Thank you,
