Congratulations on owning a Stewart LED sign!
We want to make the process of operating, maintaining and servicing your LED sign as easy as possible. Here you can find instructions on replacing LED display components, installing and troubleshooting communication methods, and more.
For general instructions on operating your LED sign hardware, including how to open the LED cabinet and vandal cover.
How the LED cabinet is opened depends on the sign model and build. For most DayStar signs and all TekStar signs, select from the tabs below. "Modular" DayStar signs and VividStar signs do not have opening sign cabinets; they are serviced through the removal of removal of dual maintenance LED modules.
Some models of DayStar LED signs include a vandal cover over the LED display. Use the following instructions to access the front of the LED modules, or to install a vandal cover after the sign has been installed.
How your LED sign transmits data to and from the controlling software is called the communication method. This option is selected at the time of sign purchase. Select your communication method below for setup and troubleshooting instructions.
Using Wi-Fi radios.
For direct line-of-sight communication over a maximum distance of 1500 feet.Short Range Wireless
Using a cellular modem.
For cellular communication using a customer-provided or Stewart-provided data plan.Long Range Wireless
Stewart signs have been designed and manufactured to provide years of trouble-free operation. This section describes some preventative maintenance steps that may be needed from time to time. We recommend following these steps every three months to ensure that your equipment is in good working order.

It's critical to keep water from entering the LED display cabinet. Check the cabinet for signs of leakage, paying particular attention to any holes - like those for lifting points or mounting poles - where water may leak in. Re-apply a silicone sealant periodically as needed.
Check all internal surge suppressors and/or fuses when a sign is being serviced. Surge suppressors are installed on all power DIN rails throughout a sign. A faulty surge suppressor will have a red or orange indicator. A good surge suppressor will have a white or green indicator.
If a faulty surge suppressor is found, obtain a replacement by scheduling an appointment with a technician.
It's good practice to check the fans and ventilation any time the sign is being serviced. Stewart signs have temperature sensors within the LED sign cabinet that monitor internal cabinet temperature. If the internal temperature reaches 152°F (67°C) the display is turned off, which stops the heat generation by the electronics.
This over-temperature condition may occur if the sign installation has blocked the ventilation, or if an excessive number of fans have failed. Ventilation can also be compromised by obstructions to airflow; for example, from leaves, dirt, rodents, insects or birds. Safely remove these obstructions if observed during sign servicing.
The louvers and modules do not require any regular cleaning. However, if you choose to clean the louvers or LED modules, use a mild soap and rinse with plain water.
A power supply converts 120V or 220V electrical current to a lower voltage, and provides it to one or more internal components within your LED display. While how you access the power supply depends on the sign model, the instructions for replacing it are the same.
A sensor may detect ambient light or temperature conditions of the sign. How it is replaced depends on the type and model of sensor. A temperature sensor may also be referred to as a temperature probe, and is only required for signs using PC-installed software.
LED modules are the square or rectangular panels that form your LED display. Most DayStar and VividStar signs use dual maintenance modules. All TekStar and some DayStar signs use rear maintenance modules. When upgrading or changing modules with different power connectors, a non-standard installation may be required.
Your new LED module will include a wiring harness to connect the power wires to the sign. This wiring harness will either connect directly to the power supply, or to another LED module.
A controller may also be referred to as a PC controller or IPC. It may be gray or dark blue in color. The controller can be identified as the component with a power button and various USB and video ports.
A receive card may also be referred to as a receiver card or logic card. It may be red or green in color. A receive card can be identified as a card connecting to the send card or other receive card with an Ethernet cable. As there may be multiple receive cards per sign side, speak with a technician to identify the card(s) for replacement.
A send card may also be referred to as a sender card or DVI card. It may be red or green in color. The send card can be identified as the card with the video cable (HDMI or DVI) running to the controller.
The USB box may also be referred to as a Mencom box. This water-tight box houses the USB port for your sign. The USB box is typically attached to one end of the sign cabinet.
