Philips TAS7505 Motherboard Replacement

Turn the speaker upside down. You will see a rubber base. Use an opening tool to lift up the sides to expose the screws.

There will be 4 exposed screws. Make sure to use the Phillips #0 Screwdriver.

When the screws are removed, you can use an opening tool to take off the plastic cover.

Now that you have removed this cover, there is another cover. This cover has a total of 9 screws that can be removed with a Philips #0 screwdriver.

Once all these screws are removed, you can take off the cover

You can now see the inside of the speaker but you aren't done yet.

Remove both rubber stands that hold up the device horizontally (one of these stands is a cover for the USB ports).

Once you pull these out, you can pull the whole sleeve to expose the infrastructure of the device.

If you are having difficulties disconnecting the battery you can pull the battery out whole in order to get a better angle to disconnect it
