Symptoms
- No response when pressing any remote button
- Remote works for some buttons but not others
- Soundbar responds to its own front panel buttons but not the remote
- Remote light doesn't blink when pressed
Likely causes
- CommonDead or weak batteriesWeak batteries are the most common reason a remote stops working entirely or intermittently.
- CommonObstructed line of sight to the infrared sensorFurniture, glass doors, or the soundbar's placement can block the signal.
- PossibleRemote or soundbar needs re-pairing (for RF/Bluetooth remotes)Some remotes use RF pairing that can drop after a reset or battery change.
- PossibleDirty or stuck buttons on the remoteSpilled liquid or debris under buttons can prevent proper contact.
- Less commonFailed infrared receiver on the soundbarA damaged IR sensor on the unit itself won't receive any remote signal.
What to do
- Replace the batteries with fresh ones, checking they're inserted in the correct polarity.
- Point the remote directly at the soundbar's front panel from within a few feet, removing any obstructions.
- Use a phone camera to look at the remote's IR light while pressing a button; a visible flash means the remote is sending a signal.
- Clean the remote's buttons and contacts with a dry cloth if any feel stuck.
- Check the soundbar's manual for a remote pairing/reset procedure and follow it.
- Try controlling the soundbar with its own front panel buttons to confirm the unit itself works.
- If available, try a universal remote or the manufacturer's companion app as a workaround.

When to call a pro
If a phone camera shows no IR flash from a fresh-battery remote, the remote itself is likely dead and a replacement remote should be ordered from the manufacturer.
