Abstract
"PROCESSOS E SISTEMAS PARA DIAGNOSTICAR FALHA EM DISPOSITIVOS DE PROJEçãO". Uma falha de dispositivo de projeção pode ser diagnosticada por monitoramento de operação inadequada do conjunto de circuitos ignitor da lâmpada de projeção. Um indicador de falha do ignitor pode ser ativado com base em uma falha monitorada na operação do conjunto de circuitos ignitor da lâmpada, para impedir notificação de falha da lâmpada de projeção incorreta.
