LG Subwoofer Repair – Fix Power, Pairing, and Red Light Issues
Subwoofer not working? If your LG soundbar subwoofer won’t pair, flashes a green light endlessly, stays on a red light, or won’t power on at all — you’re not alone.
These issues are usually caused by a corrupt firmware update or a faulty EEPROM chip. Instead of spending $100+ on a replacement, get your original subwoofer professionally repaired — fast, affordable, and backed by warranty.

LG Subwoofer Repair FAQ
How do I fix an LG subwoofer that won’t pair (blinking green light)?
A constant blinking green light usually means the subwoofer’s firmware or EEPROM is corrupted. Our service replaces and reprograms the EEPROM so the sub can pair reliably with your soundbar again.
Why is my LG subwoofer stuck on a solid red light (or has no light)?
A solid red or no light often indicates firmware corruption or a failed EEPROM/power-on sequence. We diagnose and repair the board, then fully test it under load before shipping it back.
Is it cheaper to repair or replace my LG subwoofer?
Repair is almost always cheaper. Our flat rate is $69.99 with a 1-year warranty. Replacement subs typically cost $150–$300+ and may still have pairing/firmware issues later.
How long does the repair take?
Most boards are repaired within 1–2 business days after we receive them. We’ll send it back fully tested with tracking.
Which LG models are compatible?
We support: SPN5B-W, SN8YG, GX, SN7Y, SN11RG, SPN8-W, SN9YG, SN6Y, SN10YG, SN7R, SP8YA, SPP8-W, SN5R, SPN5-W, SN5Y, SP11RA, SP60Y, SP70Y, SP9YA, EBR89625801. Not listed? Email us to confirm.
What exactly do you repair?
We specialize in EEPROM replacement and reprogramming to fix firmware corruption that causes no-power, red light, and pairing loops. We also check related components and reflow solder joints as needed.
Do I need to ship the whole subwoofer?
No. Ship only the main board (and small daughter board if you’re unsure). Use our shipping instructions for packing tips and the correct address.
Is the repair permanent?
Yes—our fix addresses the root cause and includes a 1-year warranty. We’ve repaired hundreds of LG subs with long-term success.
Do you serve international customers?
Yes. We regularly handle boards from the US, Canada, UK, EU, and Australia. Just follow the same ordering and shipping steps.

Outstanding Service
Quyen is the man! He did a fantastic job supporting me through the process of taking out the motherboard so I would be able to ship it to him safely. Any time I had a question about the process he would respond to me within minutes. My subwoofer is working great now and Quyen made the process of getting it repaired effortless for me. If you are on the fence about using his service you should go for it, you will not regret it!
