I have a LG NB3740 soundbar. Now just displays Please Wait on the Soundbar panel. No sound. I tried switching off power and then restarting, but no difference.


Since LG will not sell parts to the public I suggest you either have this one repaired if it cost effective, if not replace it.

LG LAS751M SOUNDBAR KEEPS SAYING PLEASE WAIT AND WONT TURN OFF BY REMOTE.


You need to unplug the power cord from the wall and wait 20 seconds or so. Then plug it back in and see if it works. If your unit is less than a year old, you should be able to use the warranty if needed. You should see if it is more economical to repair or replace the sound bar. Hopefully a quick reset will fix the issue.

I have a lg 60lb5200 that has a coxial ouput and i have a nb3530 soundbar that only has optical outputs. How can i make this work with the toslink i got? I hooked it up and soundbar doesnt work.


You will need an adapter. The 60LB5200 is an economy model, The 60LB5900 and above is made to work with your sound bar with no problems. Seller should have known this and not sold you this combination

How do I get my headphones to work with my Panasonic smart tv and LG soundbar?


Let me see if I can understand what you want to accomplish.
You have a Panasonic Smart TV, and an LG soundbar. But you want to use a set of headphone. I guess that your TV is already connected to the soundbar, no?
The first thing that you need to check is for an output, it must be from the sounbar, it could be a 3.5mm jack, or an RCA jack. Usually soundbars only have input, meaning that only takes the sound in, never out. If you have an audio output from the TV, you c an always try, but the soundbar won't be use then.

I have a lg 2540 soundbar connected to my 37inch lg tv. Soundbar works fine on all channels, with the exception of all the HD ones. My tv is connected to a Humax satellite box. Any ideas please.


Maybe the HD channels do not support showing the sound bar via a satellite box connection. Call the manufacturer of the box and inquire with them.

I recently purchased an LG NB3740 Soundbar and everything works great as far as sound. The problem I'm having is that when I try to access the home screen menu to search thru apps, settings and other...


Disconnect the HDMI cable and use only the optical cable for better sound. Don't connect both at the same time. Once the set sees the optical cable it switches to it.
