What's wrong?
The Weldon V-MUX Vista IV Standard is the LCD display panel on affected 2019-2021 E-One vehicles. It gives the operator a screen-based way to control emergency lighting and HVAC functions, so the display has to stay powered and responsive during vehicle startup and use.
The problem starts when the vehicle creates a negative voltage spike during startup. The display is designed to restart after voltage drops outside its operating range, but affected units do not always restart cleanly. Instead, the LCD screen can lock up, go blank, or stop functioning. The issue traces to a design update made after an older component became obsolete, which left these displays more sensitive to voltage spikes from vehicle wiring and startup conditions.
There is no warning sign before failure. The owner or operator sees the problem when the display is blank, locked, or nonfunctional, and Weldon found the screen reset after a power cycle or restart.
