First, the main reason for the projector not being powered
1: The reason for this situation is mainly the problem of the power board. The power board method supplies power to the motherboard, which causes the normal operation.
2: If there is a problem with the lighting board, it will also cause non-energization (60%).
Second, the reason why the projector bulb does not light up
1. It is possible that the bulb is broken and the bulb is not lit.
2, if the lamp office is faulty, it will also cause the bulb to not light up.
3. If there is a problem with the motherboard or the driver board, the bulb will not light up. (The motherboard is a system that works at low voltage. When it is powered to a circuit, any abnormal power supply will cause different reasons.
