I own a 5-DVD Changer with a Home Theatre System. It is an LG Model # LH-E932TB. It was working great then all of a sudden it now says ''CHECK REGIONAL CODES''. Does anyone know what to do to get rid of this message and the player working again?

DVD region code can be changed, but only for limited times. So before you change the DVD region code, you should think carefully because once you reach the max change time, you will not be able to change DVD region code again.
You can try Leawo Blu-ray Player which is a region-free player. With it, you don't need to change the region code and it can play DVD and Blu-ray discs of all regions and it's free.

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.
