Yes, the same thing happens to me with the LG TV bought at Costco in the USA, & I brought it back to Canada. This is a BUG LG SHOULD FIX.
I'm sure people from Tijuana etc. also have this problem with LG TV bought in the US & brought back to Mexico.
Wake up LG, cross border shopping exists with USA (& I'm sure in Europe too)!
I previously bought a Samsung TV at the US Costco & brought this back to Canada, & ALL SAMSUNG CHANNELS WORK IN CANADA.
I returned the LG TV since the LG CHANNELS DON'T WORK IN CANADA, when the TV is bought in the US. I'll NEVER BUY A LG TV AGAIN!
