Lenovo B470 laptop no sound repair case:
This Lenovo B470 notebook speaker and headphones have no sound, and updating the sound driver is useless. I replaced the solid-state drive of the win 10 system, and the system showed "no speakers or headphones inserted."
It is good to find the speaker. This machine has a small board, connected to the main board through the cable, open the drawing 10250-2, all the sound signals on the line are not found to have a short circuit, and there is no voltage during the power measurement.Temporarily exclude small plates.
Removing the power amplifier chip that may affect the sound output and the expansion card chip on the small board, the fault remains.
The connection resistance of the line was not found to be corroded, and it was connected to the sound card. The resistance and the bridge also had a value of 450. However, the blower bridge was tried and the bios was updated, and the fault remained.
In addition to the bridge, there is a small board left. After installing a new sound card board, there is a sound. It seems that the board is broken.
In win 10, the real sound card device is"Realtek High Definition Audio". The device that was misjudged before is said to be an HDMI audio module.
The system displays "no speakers or headphone". The headphone jack is not detected. Because the speakers are turned on the power amplifier and the amplifiers are ok, there is only a problem with the headphone jack.
Reconnect the fault board and test all signals to find the true point of failure.
