DMX Light Issue, Please Help SOS

[chris597]

So I got 4 of these lights a couple weeks ago.

Not the most reputable of brands, but the reviews vs the price seemed worthwhile. They worked fine for me until recently.

I need them for a college final project, they were running DMX good and well through a computer software and through a USB to DMX converter call Entec MKII. My professor and I have thoroughly ruled out the computer, the software, the Entec, and the cables. It seems it has to be the lights. We don't know how one of them could be running DMX perfectly one day and then all 4 of them be totally unresponsive to dmx the next, but that's basically what has happened. Here's the dmx channels and their functions:

"Chan Value Function
CH1 0-255 Dimmer (all colors)
CH2 0-255 Red intensity
CH3 0-255 Green intensity
CH4 0-255 Blue intensity
CH5 1-255 Flash rate
CH6 1-255 Macro functions (see map)
CH7 1-255 Change speed

CH 6 Macro Function Map
Values Function
01-50 Off
51-58 Red
59-65 Green
66-72 Blue
73-79 Yellow
80-86 Magenta
87-93 Cyan
94-100 White
101-150 Gradient Auto Color Change
151-200 Pulse Auto Color Change
201-250 Jump Auto Color Change
251-255 Sound Activated Auto Color Change

Notes: CH5 (flash rate) applies to all modes
CH7 (change speed) applies to values 101-250"

We've tried setting all channels to 255 except 5,6, and 7. We've also tried running up and down all the macro functions and still nothing. They still work fine in every other way except DMX too. It's baffling.
