LG - 43" Class 74B Series QNED AI Mini LED 4K Smart webOS TV (2026)

Regrettably, without details about how you are attempting to hook up the LG 43" Class 74B Series QNED AI Mini LED 4K Smart webOS TV (2026), Model # 43QNED74BUA, with your Comcast Cable Set-Top box, we cannot determine why you are unable to hook it up.. It is a standard 4K smart TV equipped with HDMI inputs, so it is fully compatible with any modern cable box, satellite box, or streaming device on the market. Depending on what connectivity your Comcast cable set-top box has, the TV can be easily connected to your set-top box. You can connect one end of a standard HDMI cable to the HDMI Out port on the back of your Comcast box, and plug the other end into either HDMI 1 or HDMI 2 on the back of your LG TV. Then turn on both devices, press the Input/Source button on your LG remote control, and select the corresponding HDMI port you plugged the box into. If you prefer not to use a physical cable box in that room, you can download the Xfinity Stream app directly onto the TV from the built-in LG Content Store. This allows you to stream your live Comcast programming and On-Demand content entirely over your home Wi-Fi network. If your TV keeps forcing you back to the LG smart home menu when you power it on instead of launching your cable box input, you should disable the Home Auto Launch option. You can turn this off by navigating to Settings ➔ All Settings ➔ General ➔ System ➔ Additional Settings ➔ Home Settings on your TV...^Ivan.
