Solutions to common problems of beam light bulb not lighting up

If the beam light bulb does not light up, you can follow the steps below to troubleshoot and repair:

        1. First, check whether the bulb is burned out. How to detect: Simple method, install a good bulb to test, if it is a burned out bulb, just replace it. If it still does not light up after replacing the bulb, check the lighting device, that is, the lighting board, and consider the lighting board.

        2. If there is no response when turning on the machine, check whether the power supply is burned out. When turning on the machine and checking the power supply, use a multimeter to check whether there is voltage output. (If it is burned, there will be no voltage output; you need to replace the power supply, which is a core component that supplies electricity to the entire lamp).

        3. If the light bulb is sometimes good and sometimes bad, check and replace the light bulb first. If the light bulb is still sometimes good and sometimes bad after changing it, check whether the fan next to the lighting board is broken. If the fan of the lighting board is broken, the light bulb will be sometimes good and sometimes bad, and the fan must be replaced.

        4. If the three problems are still not checked, check whether there is a 5V voltage power supply wire terminal on the lighting board, and use a multimeter to measure whether the 5V voltage has arrived. If not, it is necessary to consider that it is a problem with the motherboard and the motherboard needs to be replaced.
