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 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,
