LED outdoor screen water intrusion short circuit claim case

An outdoor LED bulletin board installed in a residential complex in 2023 went black after just eight months due to continuous rainfall. Professional inspections revealed cracking and aging of the screen’s sealant, allowing rainwater to seep into the internal circuitry, causing a short circuit and completely burning out the core driver board. When the homeowners contacted the installation company, they refused repairs, claiming the six-month warranty had expired and that the rainfall was considered force majeure. They offered only a high-priced replacement (offering a price exceeding 70% of the initial installation fee). The community homeowners’ committee, after compiling evidence, discovered that the LED board was purchased from an unqualified, small manufacturer and installed without undergoing IP65 waterproofing testing. They have now joined over 50 other homeowners in filing a complaint with market regulators, demanding the manufacturer assume responsibility for repairs and compensate for lost work time.
