The IPTV application on the lg SmartTV problem

[Rayancaleb]

HI
I installed IPTV applications on my TV today (LG 42LV375S-ZC) and I have a problem. Well, the test channels that I received during the installation work without a problem but when I run the program from the list, which I updated myself, it turns off the TV and then turns on again. Could someone help me? What am I doing wrong? What could be caused by the continuous shutdown of TV when trying to launch any channel updated by me?
Thanks

I did not find the right solution from the internet.

Hello,

What is the name of the application?
How do you install it on the TV?
