Technical Support

We provide a full range of professional technical services

Service we provide

· If there are any issues with the display module during the warranty period, you can choose to send it back to the factory for repair or to our service point. We will arrange for professional technical personnel to provide repair services for you and conduct another test. Once the test is correct, we will package it and send it back to you.

· If there is a problem with your display, we will first provide remote support to guide troubleshooting. If you need, we can also arrange for technical personnel to the project site within the specified time to support and provide on-site solutions. If the issue cannot be resolved on-site, we will first replace the spare parts to ensure the normal operation of the screen and report the issue to the relevant departments for more detailed testing to solve the problem.
