I did some research on this, but was unable to find out how to adjust bass and treble control individually. this is a link to the users manual (not sure if you have or not). You can download it if you like. I did, read through it, and didn't find anything to solve your issue. Unfortunately, this is a common setup for a lot of newer sound systems. Since they are digital, to achieve superior performance, they keep the settings digital and dont allow for fine tuning of the lower and upper frequencies (bass and treble).


I hope this helps.

As for the sound, there are some players that has different volume controls for each speaker, so check the volume of the speaker through your remote.

Or maybe the sound I.C of the player is bad.

You might just loose the Player with a screw driver and you may probably see what's wrong with it and if you don't, couple it back and put it on, don't be surprised to see your player working properly.

My Samsung player hung such that no button functions. What I did was just to loose it and clean the inside and by the time I coupled it back, it started working perfectly up till now.

Note that this could only work if the player is not having any major fault.

I wish you the best.

I have the same problem. I tried to get it fixed by sending it to my retailer (Best Buy) who then sent it to the LG company and they said everything was fine. But there was one problem with their diagnostic...it wasn't. The subwoofer worked fine when i originally bought it, but about a month later it would not work or it would work intermittently. It literally takes about an hour for this thing to start working, and now my right speaker has started to not work. My judgment is that this product is poorly made and the service people at LG are incompetent!

press the "2" button on the remote while pressing & holding the stop button on the device, something like OP 86 will come up on the lcd display, repeat the same procedure and press "enter" afterwards, the device should restart and the problem should be solved.

Hook a digital optic cable from the Tv's digital ouput to the Recievers digital sound in. This should fix it. You might have to switch the input of the reciever.

Check which Channel you are using on the Remote. i.e. 2.1 Multichannel or Auto the Centre Speaker and the 2 rear speakers don't work if its 2.1 channel setting

be sure bluetooth is on. also turn both headphones off. once headphones are off, start scanning for bluetooth devices. once scanning, hold the power button down on both earbuds for ten seconds or until theyre both flashing red and blue. your device should then notify you about pairing.

If the subwoofer works perfectly when tested separately, something is wrong with the subwoofer output of your LG home cinema - perhaps it is intended for use with a powered sub.

Have you changed the Regional Code of the DVD changer? Changing of Regional Code of the Changer is permitted for 5 times. To view movies of different region code, some people change it. Suppose you or someone have viewed a movie of different region movie after changing the region code & now you are trying to view a DVD of your region. In this case you will have to change the region code to your region. Changing of region code is available through the setup of the Changer.
