1, проверьте оборудование
Open the back cover of lcd advertising machine, and use multimeter to measure whether the power amplifier on the driving board is energized and normal. If the power amplifier is energized normally, the next step is to check whether the connecting cable of its horn is normal.
2. Replace accessories
If the power amplifier of lcd advertising machine driver board is abnormal, replace the driver board; If the horn is not normal, replace it. In addition, generally, the connecting cable of lcd advertising machine horn is the easiest to fall off if it is not firmly connected. If it falls off, weld it with a soldering iron. If the speaker is noisy, it is that the driving board of the advertising machine is damaged. Replace the driving board immediately.
The above is the solution that Ruiguan brought to you when there is no sound in lcd advertising machine. I believe everyone knows about it, and you won't be in a hurry when you encounter such a situation.
