Is there a flat screen tv with built in converter box?

Yes, there are flat-screen TVs with built-in converter boxes. These TVs include a digital tuner that allows you to receive over-the-air (OTA) digital TV signals without a separate converter box. This means you can connect the TV to an antenna and watch digital TV broadcasts without any additional equipment. Many manufacturers such as Samsung, LG, Vizio, and Sony offer flat-screen TVs with built-in digital tuners. You can verify the presence of an integrated tuner by checking the product specifications or looking for relevant labeling on the packaging or within the TV's settings menu.
