Technographic Displays provides on-site and factory-based maintenance services for all its own LED displays, control systems and also many of the displays previously manufactured by Invision.

The photographs on this page show an Invision display, originally installed in 1995, being upgraded by Technographic Displays. The upgrade entailed on-site fitting of new LED display modules, designed by Technographic Displays to be superior in every respect to the originals. The new LEDs are on the right of the photographs (above and right). The refurbished display is shown below:

The refurbishment has extended considerably the lifetime of the display, without the need to replace any driver boards, controllers, housings or power supplies, meaning a significant cost saving for the customer.

Technographic Displays still undertakes maintenance of Invision's fleet of mobile video screens plus many of the permanent installations, either directly for screen-owners or at component-level for third-party maintenance companies.
