Philips TAS7507 Troubleshooting

The speaker will not respond or show any sign of powering on.

Make sure that the speaker has been fully charged to 100%. Try charging it overnight to ensure it has been fully charged which you tell by the 4 blinking white lights on the button. Each white light represents at least 25% battery of the speaker's battery.

See here to look over the Motherboard repair guide which also helps replace the capacitor.

Sometimes the power button gets stuck which prevents you from turning on the device. Try cleaning the power button and pushing the button hard until you hear a clicking sound.

The speaker will not hold charge or will not charge.

• Make sure that the USB socket is properly connected to the speaker
• Make sure that the charger you're using for the speaker actually works
• Make sure to charge your device for at least 4.5 hours

Ensure the charging cable is properly inserted into the speaker and the power source. If the charger is properly connected and the light on the speaker does not turn on to indicate charging then the power source may be incorrect. Check to make sure the power adapter is appropriate and is delivering 5 volts and 2 amps to the speaker.

If the charger is properly connected and the charge light on the speaker is on, but the speaker only turns on while plugged in, then the battery may be faulty. It may be damaged preventing it from holding a charge, click here to find out how to change the battery.

Inspect the charging cable for tears in the insulation. If you can see the silver or copper wire inside then the insulation is severely damaged. Inspect the exposed wire to see if it has broken or torn. If so, you may need to purchase a new cable. Monitor the speaker lights to see if the charger is actually charging to find out if it's the charger or speaker.

Or if USB-A and/or USB-C ports have damage; click here to see USB-A & USB-C port repair guide.

Note: The device has multiple speaker connections abilities

• The Bluetooth may be out of connection range
  • The device's Bluetooth range is 66ft (20m) so make sure you are within this range when pairing
• You might not be pairing with the correct device
  • Make sure that your device is in pairing mode
  • The Bluetooth Profile may be one of these two (This is how the speaker will show up on your device's pairing screen):
    • A2DP
    • AVRCP
• Restart the device and try again
• Click here to see the Motherboard repair guide which also helps replace Bluetooth.

• Make sure to press and hold for 2 seconds to enter Bluetooth pairing mode
• If you can’t find the device then try again with the same method
• Try to forget the device in your Bluetooth settings

• Blinking blue quickly — Ready for pairing
• Blinking blue slowly — Reconnecting the last connected device
• Solid blue — Connected

The speaker can no longer produce the original quality of sound and instead makes a muddy or sharp sound that is unpleasant to listen to. Click here to see the Speaker Repair guide.

Turn the volume down. Having the speaker at max volume over long periods of time can damage the speaker or push it beyond what it can handle.

Choose better or higher quality cables for your speaker because if you use improper cables for the speaker it can lead to overheating because the cables fail to manage and distribute the heat produced. If the damage is too much we will either have to replace the speaker or repair the parts that are damaged.

The volume of the speaker is very low or quiet even though you have increased the volume on the speaker.

The distance can result in the volume getting lower or sometimes cutting out since the signal is too weak for the speaker to hang on to. The battery on your phone or your speaker can also influence the loudness of your speaker due to it struggling with power while also trying to maintain the Bluetooth connection.

Check who is connected to the speaker multiple people can be connected to a speaker and the speaker can only output the sound of one device. If you are the second one to pair with the speaker it will say that you are connected but no sound will be outputted. So double-check who is connected or reset the speaker and connect to it again.
