Have TV Questions? Ask a TV Technician

Hello, I'm Shahid. Sorry to hear that you're having trouble with this but I'll do my best to help.
Lets try one thing that might help. Unplug TV power cord from wall outlet for 5 minjtes to reset, replug back in, turn it On and run network setup again to make fresh connection with router and check if it helps to get better internet speed for video streaming?
If it doesn't fix the the issue then I'm afraid it would be either wifi board or main processor chip on main board of TV problem which isn't capable to process the internet data properly and causing the lag. I am really sorry about this and you are going to have to return the TV to have it replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you. I would recommend different model/ brand as replacement to resolve the problem. I hope these info will help. If you have any additional questions, feel free to ask. If you're satisfied, please rate me a 5-star at the top of your page. Thank you.
