Smartfade LEDs burnt out


LEDs burnt out
Console may also not be outputting DMX

Explanation of Issue

This is a common issue for older Smartfade consoles, but has been known to occur in newer Smartfade consoles. This primarily affects the blue LEDs. The common repair is to replace the LED and change the accompanying resistor to a higher value

LEDs burning out can cause strange effects during use. Most often, this manifests as other bump LEDs lighting up when a bump LED is pressed, or can cause the console to appear to have no DMX output, as the console may be in blind mode that is normally indicated by a blue Next LED

If your console is not outputting DMX, press the Next LED and re-check if there is DMX output
