To changethe Region code on your DVD player, open Control Panel - System - Hardware -Device manager, and click on DVD/CD ROM drives, then right click on the DVDdrive and click Properties then click on DVD Region.
You can enter a new region and it also shows you how many changes have been made.
NOTE you can make only 4 changes and the player will lock permanently on the4th change.
If you want to play DVD from any region you maybe able to upgrade the firmwareto make it region free BUT if you make a mistake or installed the wrongfirmware the player will be a piece of junk.
The best solution to make the player region free is to install a piece ofsoftware that allows you to play DVDs from any region. There are severalavailable on the Internet but my favourite is DVD-Region Free From:-

There are several reasons that this could happen and given the cost of a new one VS the experience you need and the tools and test gear, it would be best to get another one.
Could be a sticky power of function key, bad laser, bad motor, bad power unit, bad detector

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.

Did you check all connections? All audio settings? If yes and it didn't help I think better will be call to specialist in this field. I recently bought new home cinema Ugee 1910B and it works perfect. Quality of video and sound is great.

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.

Depends what inputs and outputs your TV has, and whether you also have a cable box or other source.

LG Audio Players... | Answered on Nov 16, 2019


Whether the remote, or using any buttons on the unit, those inputs go into a microprocessor(computer within your unit). There can be other issues, but that is the most likely.
If you are interested in having your LG repaired, please look to my website at audioserviceclinic.com. Thank you.

if any of the selector switches is dirty this will happen.
a drip of wd40 into every micro switch should solve it unless it is a dry solder joint on any of the switches.
