Troubleshooting and Resolution
01In the event of issues with the display, audio, or control system, we perform remote preliminary diagnostics and, if necessary, schedule on-site technical support.
Technical Support and Maintenance Services
We provide technical support and maintenance services to ensure the uninterrupted operation of your LED displays, digital signage, and AV systems after installation.
Scope
What Does This Service Cover?
The most critical phase of an AV system often begins after installation. No matter how well the display, audio system, or video conferencing infrastructure is set up, software updates, hardware wear and tear, or changes in usage habits will eventually create a need for technical support.
At Koz Teknoloji, we support our customers with fault diagnosis, spare parts procurement, and periodic maintenance both during and after the warranty period for the systems we install.
Periodic Maintenance
02We recommend regular maintenance visits to prevent issues such as dust buildup and loose cable connections that may occur over time, particularly in LED display and video wall systems.
Spare Parts Redirection
03We manage the process of quickly sourcing the correct replacement part for a faulty module or component.
Software and Firmware Updates
04We ensure that content management software and hardware firmware updates are applied without compromising system stability.
Remote Diagnosis and Preliminary Diagnosis
05Using content management software and a network connection, we remotely monitor the screen’s status and determine whether the issue stems from hardware or the broadcast feed without the need for on-site intervention.
Spare Module and Parts Planning
06To ensure color consistency on LED screens, spare modules must be selected from the same production batch. For critical installations, we carry out this planning during the project phase.

The frequency varies depending on the environment. For LED screens in dusty or humid areas, maintenance every six months is generally sufficient, while in controlled office environments, annual maintenance is usually sufficient. The determining factors are the screen’s operating time and the conditions of the area where it is located.
Module surface cleaning, inspection of cable and connector connections, examination of the power supply and cooling components, measurement of color and brightness differences, and software version verification are performed. Any wear and tear detected is reported.
After examining the system, we evaluate it. The brand of the hardware used, the availability of control boards, and the availability of replacement parts are key factors.
Note whether the entire screen or just a portion of it is affected, when the problem began, and whether there was an update or a power outage beforehand. This information significantly speeds up the remote preliminary diagnosis.
