What to do if there is no sound from my Panasonic CQ-C5400?

First, check the wiring to ensure the power cord (battery, ACC, and ground) is correctly connected. Verify that the MUTE function is set to OFF. Also, make sure the speaker lines are correctly wired, and there are no breaks or poor contacts. If a demonstration screen is active, press the display button to exit it. If the demonstration screen appears frequently, check the battery wiring, ensuring it's correctly connected and always powered.
