Error name: Speaker test failed
Error code: #10310
The speaker test will play the user a sound that is confirmed by user-input. If the sound is played by the test, and you select you did not hear it, it will give this error.
Make sure the connector is well seated using the guide below and polarity is correct (Red on the Right, by the +).
Also inspect the speaker, found at the back of the Touch Screen, whether its wires are secure, and no solder pads have come loose.
