Polk Omni S2 Motherboard Replacement

Description: The motherboard is the "brain" of the Polk Omni...

Steps:

1. Pry off the grille by pulling on the top middle part of it.
2. Remove the grille carefully, but note that it takes a large amount of force to remove. If it seems like you're bending the grille too much, try pulling on it from the bottom instead.

3. Remove the eight 12 mm screws securing the front cover using a Phillips #1 screwdriver.
4. Like the grille, pull from the top middle of the gray cover and slowly remove it from the speaker, like separating a sub roll.
5. Be careful of the wires between the cover and the motherboard. If you pull the cover apart too far, you might damage these wires.

6. Remove the two square cotton pieces.
7. Unplug these three wires plugged into the motherboard by gently pulling and wiggling the wires until they're unplugged. Grip the wires close to the end to avoid damaging them.

8. Use a Phillips #1 screwdriver to remove the four 9.5 mm screws.
9. Use a Phillips #1 screwdriver to remove the 9.5 mm screws with washers.
10. Be careful not to lose the washers when removing the screws, and make sure they go back where they belong when reassembling.

11. Remove these two pieces of tape holding down black wires by peeling very slowly. You can use a spudger to pry them off and avoid tearing them.
12. Remove these two taped down metallic strips by peeling very slowly. Again, a spudger helps to ensure the tape isn't damaged.
13. Don't worry too much about bending the strips a little bit — they bend back easily.

14. Carefully remove the motherboard.
