A:Answer Hello jnguyen6
Thank you for your inquiry.
The LG 2.1 Channel Sound Bar with the Wireless Subwoofer, Model # NB3530A, has 2 Digital Optical Inputs and a Portable Audio 3.5mm Input with which you can connect external devices with that do not have Bluetooth capabilities!
What you will need to check on the TV you intend to purchase is if it has Optical Outputs on it or RCA Stereo Audio Outputs (you will need the correct Audio cable for this!) It's not a matter of compatibility, it's more about connectivity!...IFV
