LE Trouble

Basic Info for Lynx Express (LE) Trouble Shooting

Here is some previous info that other members started putting together Click Here

Slow Seven Segment LED Scroll

* Possible bad firmware loaded - Reload the LE firmware from here Click Here 
* Possible defect pic - replace pic and load LE firmware

All Channels Flickering

* Possible too cold inside case - Add 3 C7 lights to warm up the board

No DMX Input Wired

* Plug the cat5 cable into the DMX out to see if the Data LED comes on (ver 5 pcb) or if you start to see lights working with other versions
* You have the Data led backwards so it is shorting out the DMX data
* You have the wrong resistor in line with the DMX led causing problems

Triac (bad/stuck etc)

* First swap out 6 pin opto chip above Triac with another one on the board where the triacs are working fine ( with power off of course)
** If the problem follows the opto then the opto chip is bad
** If still on then remove the opto and try again - if that doesn't turn off the Triac then the Triac is bad
