Common VX600 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 →
A receiving card / group of cabinets shows offline on one Ethernet port
Likely cause: Exceeding the 650k-per-port limit or wiring Port 1 out of sequence drops cabinets past the overload point offline; re-balancing the load and starting the chain on Port 1 brings them back.

Cabinet or whole screen goes dark / will not light up after power on
Likely cause: On the VX600 a cabinet that boots without a valid config file stays dark; pushing the config file back down and reconfiguring the screen restores the normal output image.
- Step-by-step fixGet the fix →
Configure the screen without a computer / recall a saved look fast
Likely cause: Onboard preset memory and front-panel config let an operator run and switch layouts on site without carrying a laptop.
- Step-by-step fixGet the fix →
Genlock and Low Latency cannot both be turned on
Likely cause: The Bypass datapath cannot simultaneously satisfy external genlock timing and the frame-buffer bypass needed for low latency; Video Controller mode buffers differently and allows both.

HDMI monitoring output shows a fixed 1920x1080 regardless of screen size
Likely cause: The monitor port is a dedicated fixed-format preview tap, not part of the scalable LED canvas, so its resolution does not follow the display size.

Key electrical/physical facts for rack planning and power
Likely cause: Having verified power, weight, size and I/O on hand speeds rack layout, power budgeting, and cable prep for the VX600.
- Step-by-step fixGet the fix →
Need to update VX600 firmware / running old firmware
Likely cause: The VX600 has no USB-host update path; the program-loading tool inside NovaLCT/V-Can pushes firmware over the network port, and a matched NovaLCT avoids protocol mismatch errors.
- Step-by-step fixGet the fix →
Receiving card blinks 3 quick flashes then pauses, screen black
Likely cause: The 3-blink-then-pause pattern isolates the fault to the input stage (link OK, no video), so the fix is upstream of the cards at the controller input, not the cabinets.
- Step-by-step fixGet the fix →
Screen flickers or a region blacks out and returns intermittently
Likely cause: Flicker that follows a swapped part points to that part; flicker that stays put with stable signal usually indicates power sag, so PSU checks resolve most cases.
