You can try a different power supply
Get one of the universal after market supplies for the laptop
Different TVs have different quality and sensitivity
My HP laptop is less than a foot from my Visio TV
Both are plugged into the same power strip
I can watch the news while working this forum
If it's an inconvenience to charge the laptop someplace else
I would get another charger for it
If that doesn't work?
Your options are limited, replace one or both TV and laptop
Or keep charging in separate rooms
I'm assuming you would like to use the laptop with charger while in the same room with the TV
