Common ColorBlast TRX errors & problems
What techs run into most, and what's usually behind it. The step-by-step fix for your exact unit is in Ask Roadie.
- Step-by-step fixGet the fix →
What DMX modes does it have?
Likely cause: Corrected to the TRX RGBAW channel modes from the manufacturer spec sheet; the prior text described the legacy ColorBlast fixture.
- Step-by-step fixGet the fix →
How do I address a ColorBlast TRX?
Likely cause: The TRX added onboard touch-sensitive menus, so unlike the legacy ColorBlast it can be addressed at the fixture without QuickPlay Pro.
- Step-by-step fixGet the fix →
End-of-run fixtures dim, color-shift, or drop out
Likely cause: At 24 VDC the current is high and undersized/long conductors cause significant voltage drop, starving the LED drivers.
- Step-by-step fixGet the fix →
Fixture is completely dark even though DMX is patched
Likely cause: The PDS is the fixtures power supply and DMX-to-CKDMX converter; without it the fixture has neither 24 VDC nor data.
- Step-by-step fixGet the fix →
Fixture running hot / worried about LED life
Likely cause: LED lifetime and lumen maintenance are strongly temperature-dependent; the diagnostics menu exposes the junction/ambient temp so techs can act before degradation.

Full specs / what is a ColorBlast TRX
Likely cause: These are the manufacturer spec-sheet figures for the base ColorBlast TRX (do not confuse with the RGBAW ColorBlast 12 TRX or the outdoor ColorBlast 12).
- Step-by-step fixGet the fix →
Can I use the ColorBlast TRX outdoors / is it weatherproof?
Likely cause: People routinely assume all ColorBlast fixtures are the IP66 outdoor originals.

How do I set the address / fixed color / run diagnostics on the fixture itself?
Likely cause: The onboard touch UI makes the TRX self-addressing - a key difference from the ColorBlast 6/12 which required QuickPlay Pro serial-number addressing.
- Step-by-step fixGet the fix →
How do I update firmware on a TRX?
Likely cause: QuickPlay Pro is the manufacturer commissioning tool that talks to fixtures via the PDS to read/write firmware and configuration.
- Step-by-step fixGet the fix →
How many TRX fixtures can one power supply drive?
Likely cause: Each fixture draws 50 W max; the PDS wattage and per-port design set the fixture count.
- Step-by-step fixGet the fix →
TRX colors do not match my other/RGB fixtures
Likely cause: The extra Amber and White channels expand the palette but make RGBAW output look different from plain RGB rigs; RGB-in modes constrain it to a matching gamut.
- Step-by-step fixGet the fix →
Fixture dead or faint glow, no DMX response
Likely cause: The PDS provides both 24V power and data per port; exceeding heads-per-supply starves fixtures below operating voltage.
