The CDU has been declared obsolete by the OEM, furthermore, product support had been withdrawn by the existing supply chain. The depot was now in a critical situation whereby all the float of CDU\u2019s had been declared \u201cunrepairable.\u201d One unit had been in an unrepairable state for 10 years. TP Matrix were invited to investigate possible solutions.The solutionTP Matrix performed a Condition Assessment on a sample unit and quickly determined the units were repairable. Two of the faulty units were repaired, tested and installed on vehicles within 4 weeks. TP Matrix engineers were present on site to witness the installation and testing. During the Condition Assessment it was determined that the main component, a Vacuum Fluorescent Screen was obsolete. Although a later version screen was available, this was not compatible with the CDU. The only viable solution was to design an Interface Card to allow the original control electronics to communicate with the new screen.
