I was able to measure the voltage out of the ELN-60-24 with the outputs of the EldoLED set to various levels and it gave a constant 24.1V. Due to the urgency to get the display up and running I didn't have the time to check current or quality of the DC. I have spoken to one of our other technicians who deals with LED installations a lot more than I do (He was on annual leave when I originally posted this) and his approach is if the LEDs are doing anything strange swap the driver/PSU and see if this solves the problem. Thanks for all the help in solving this.

The faulty unit was a ELN-60-24 replaced with a LPF-60-24 I think. The main question is why was the faulty Driver/PSU causing the EldoLED to output corrupted DMX.

I have found the problem. All of the LEDs where daisy chained using Eldoled POWERdrive 90D controllers powered by Mean Well 60W 24V drivers. The second driver in the chain appears to be faulty as when the LEDs powered by this one are faded up all of the LEDs after it start to flicker and flash randomly. Replacing the driver has fixed the problem. I assume that the driver was no longer able to supply sufficient current for the LEDs which was causing the controller to start sending out corrupted DMX to all of the other controllers down the chain.

Thank you for all your help. I purchased a Swisson XMT120 which has allowed me to start working through the system eliminating components one by one. I have now worked out that a set of 3 LED uplighters is causing the problem, I now have to work out why. The installation has 8 objects which are each lit by 3 led uplighters and 6 LED RGB panels. With the Swisson controlling the lights (LanBox Disconected) when one set of 3 uplighters (which have individual DMX addresses) are lit all of the other LEDS in the entire display randomly flicker and flash even when their DMX Chanel is set to zero. I am assuming that the controller for these uplighters is faulty and somehow corrupting the DMX signal to the other fixtures. The objects are difficult to move and I am not sure where the controllers or ballasts are situated in the structure. So I have a lot of digging about to find everything before I can even start swapping out components. Wish me luck and thanks again for all the help.

Thank you for the quick reply. The system is connected to a LanBox LCX which is being sent data via artnet which has been deeply embedded into a much larger content management system. The company that wrote the CMS went bankrupt many years ago and we have no paperwork as to how the system can be edited. We want to get the chase sequence and possibly edit some of the steps. Then transfer it to a simpler DMX playback device as we no longer need the complexity that the CMS has.The Swisson seems like something we need in our tool kit but as the chase is fast I can't see how we would be able to see each individual scene as it is running.

We have a DMX playback unit which is becoming very unreliable. It runs a complex light show over 147 channels and there is no documentation as to what the sequence is. Is there any hardware that I can connect to the output which will show the channel levels step by step.
