LG Subwoofer Replacement Board FAQ
Will this board fix an LG subwoofer that won’t pair?
A continuously blinking green light can be caused by firmware, EEPROM, or main board failure. Replacing the faulty board can restore communication between the subwoofer and compatible LG soundbar.
Will this fix a solid red light?
A subwoofer that remains on a solid red light may have a firmware, EEPROM, or main board problem. If the original board is the cause, replacing it can restore normal operation.
Will this fix an LG subwoofer with no power or no light?
It may. No-power conditions can be caused by the main board, but they can also be caused by other components inside the subwoofer. We recommend checking that your original board matches the replacement before ordering.
Do I need to send you my old board?
No. This listing is for the replacement board itself. You do not need to mail your original board to us.
Is this a repair service?
No. This listing is for a replacement LG subwoofer circuit board for $89.99. We ship the board directly to you for installation in your compatible subwoofer.
How difficult is installation?
Installation normally requires unplugging the subwoofer, removing the rear panel, disconnecting the connectors from the original board, removing the mounting screws, and installing the replacement board in its place.
Do I need to solder anything?
For compatible models, the replacement board is designed to replace the existing board using the original connectors and mounting points. Installation generally does not require EEPROM programming or board-level soldering.
Which LG models are compatible?
Supported models include SPN5B-W, SN8YG, GX, SN7Y, SN11RG, SPN8-W, SN9YG, SN6Y, SN10YG, SN7R, SP8YA, SPP8-W, SN5R, SPN5-W, SN5Y, SP11RA, SP60Y, SP70Y, SP9YA, and EBR89625801.
Because LG may use different board revisions within similar models, we recommend comparing your original board number before purchasing. Contact us if you are unsure.
Does the replacement board include a warranty?
Yes. The replacement board includes a 1-year warranty.
Why replace the board instead of buying another subwoofer?
A complete replacement LG subwoofer can cost significantly more and may be difficult to find for older soundbar systems. Replacing the failed board allows you to keep your existing enclosure, speaker, and soundbar system.
Do you ship internationally?
Yes. We serve customers in the United States, Canada, United Kingdom, European Union, Australia, and other supported destinations.
