Abstract:LED screens are often used in Road side advertisement screens, they last long and can withstand the harsh outside environment. Even though these screens are generally well built, this doesn’t mean they don’t need to be repaired. This paper aims to research how Prognostics and Health Management (PHM) can be implemented in large scale LED screens, to go from reactive maintenance to preventive maintenance. Mainly maintenance records of these screens are used to analyse the kind of failure modes that occur in these screen and whether they are suitable for PHM. These screens turned out to mainly have issues with corrosion on the cooling fan of the power supplies and water damage in the LED tiles. The internal diagnostics system is unfortunately not very expandable, causing possibilities to be limited in terms of monitoring important parameters.
