Answer: 
We regret the trouble you have experienced with this television. The latest update appears to have been an update/addition to certain apps. The TV should not be turning off when a game system is activated. The unit may require service. To make service arrangements, you may either contact our Customer Interactive Center at 800-243-0000, or you can check our Repair Provider Lookup on our website, at http://www.lg.com/us/support/repair....

NTSC and PAL

I just purchased the LG 55LA7400 in the USA.
Within 2 years I expect to go back to Europe.
Will this TV work in Europe with the PAL system? Or, with this new HD, the video system is not an issue anymore?

Thanks

In this website:
http://www.lg.com/eg_en/tvs/lg-55LA7400/technical-specifications
it states under "Broadcasting Systems":
"Analog TV Reception (PALⅠ, PAL/SECAM BG/DK, NTSC M)"
Also, when a multi-region/multi-system DVD player was set to PAL and playing an European Region 2 DVD, the TV worked fine!

I apologize, but no; the 55LA7400 has been designed for use within the United States only. It is not designed for compatibility with the PAL signal format.
