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.

LGSN5Y woofer
I live in Costa Rica and my subwoofer died. I took it to a local repair guy here and he told me it needed a new bluetooth reciever but that part isn't available here. He said he could order a new motherboard from LG but with shipping to CR, i was looking at over $200. I found Quyen while searching for how tos for fixing this thing. My wife was planning a trip to the states and took the motherboard tobsebd over to him. She mailed it the day she arrived in the states and 2 days later he had received it, repacked it, and shiiped it out back to her. Ahe brought it home, i reinstalled, and now i have my sound back! I am so glad to have found him.

Fantastic service A+++

Excellent and fast service
He fixed my subwoofer for my LG sound bar combo.Was extremely fast getting it repaired and shipped it out same day as the repair. Honestly couldn't recommend him enough! No one else was able to offer a permanent repair without just replacing the whole circuit board which would wind up having the same issue eventually. Get it fixed by him and it will be fixed right. Thanks again

Incredible fast work.
Found Quyen on reddit/YouTube after my subwoofer stopped turning on. He had it fixed, shipped back to my house and working in 4 days time. I was amazed. This guy is doing LG's customer service all by himself. A+ A+ A+

LG subwoofer repair
I used this service a little while back and am very pleased with the results. I thought I was going to have to get a new sub. But after watching his video and texting with him, I gave it a try. The service was great..very fast and he kept me apprised of everything. No hidden fees or surprises. Highly recommend this service.

Subwoofer repair
I highly recommend Quyen in fixing your subwoofer that won’t power on OR connect wirelessly to your soundbar anymore. I had both of these issues, sent him my circuit board and had it back in under a week. Works like brand new now. Thanks
