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.

LG TV and sound bar? This is for you
I like the connectivity I have between my LG tv and sound bar but when my subwoofer went out, I was contemplating replacing the sound bar. Luckily I found this service and within 4 days of placing my order, my subwoofer is back up and running, making everything sound great again! Much cheaper than replacing the entire system. Would recommend, especially if you have interconnected LG products.

Awesome subwoofer repair!!!
Fantastic service!! I purchased a LG soundbar (SN6Y) with wireless subwoofer from Amazon and the sub wouldn’t pair up with the soundbar. No green light came on ever and I knew then something was wrong. I bought the system for a pretty good price and liked the soundbar and was hoping to get it fixed rather than the hassle of replacing it. After looking online I came across a video on YouTube of this guy fixing LG subwoofers and decided to give him a shot. I messaged him and he responded back right away with instructions on how to take it apart and what to send him. I did this and he did an awesome repair changing out the faulty chip on the motherboard. I live in Vancouver Island Canada and was up and running in days not weeks. I couldn’t believe how fast he got it back to me and I have nothing but good things to say about this service for sure and recommend it to anyone 1000%

Subwoofer not turning on
I almost throw away my Soundbar system and spend more money on a new one. I was searching on the Internet and YouTube about similar problems and read about this man. He's the savior, my Soundbar works as the same day I got it. Thank you again you are the best!

Fast and legit!
It works! I wish I'd found him before wasting hours troubleshooting and griping at LG reps on the phone. Shipped the board went to the opposite coast, got it back, installed it, and optested sat within the week.
