Many makers are regionalizing the HDTVs. So only LG can answer if you can change the region.
I am planning to take along my LG SMART TV (LG 47LM6400) to India.
I checked LG has also has a LG SMART TV Apps website for India.
My question -
1) Will I be able to use my existing SMART TV apps in India
2) Can I download apps from India LG TV Apps website and use them.
