The motherboard for any electronics should only be replaced after all troubleshooting has failed. This is an extremely fragile component and requires patience to remove safely. However, this motherboard was very easy to remove and can be done with only one person though, we recommend asking a friend for help just to be safe.

To begin, remove the 8 screws locating on the back of the soundbar. These can be removed with the ifixit screwdriver equipped with a Phillips'head in size J1.
-
The cover will lift up, but there will be wires underneath connected to the cover that need to be unscrewed.
-
The 8 screws on the back cover, as well as the screws removed in the following steps, are all the exact same length (approx. 1 centimeter). Keep track of all screws but do not worry if they become mixed up.

-
Remove the two screws using the Phillips #1 screwdriver. Once they are unscrewed, the panels will hang loose allowing unobstructed access to the motherboard.

-
Remove the three sets of wires plugged into the motherboard (image 1). These are removed by gripping the base of the wire firmly and pulling straight up.
-
Unscrew and remove the four screws (two on either side) to release the motherboard from the rest of the soundbar (Images 2 & 3).
-

-
Now that the soundbar is unscrewed, carefully lift the motherboard up and remove the wire attached to the underside of it. To do this firmly grasp the wires at the base (image 1) and pull them straight up.

The motherboard is now completely detached.

Hi
Did you find where to buy a motherboard replacement?
Where do i buy a motherboard replacement?
This info is useless if you know the motherboard is broken and needs to be replaced but you don’t share the link to buy it again! Otherwise you have to dispose the whole bar in the trash can.
Guessing no one ever found where to buy a motherboard?
Probably at mother boards .com, if not trash it goes.
Called Polk. They do not sell the motherboard. if under warranty, they will have Massimo send you a new soundbar and won't even ask for the old one to be shipped back! if not under warranty, then congratulations, you now have a very expensive anchor which can be attached to a chain and thrown overboard to stop your small boat from moving while fishing.
The motherboard is a very easy part to replace. a few screws, a few plugs and a ribbon cable. But Polk won's sell them to you. Don't purchase Polk products unless you want a product that has no viable repair options.
Hi .do you repair or can i buy from you?
