I have modelL2614XW02 why can’t do a channel serch
First ,what is the current input source? If the source isn't connected to the coaxial antenna (RG59) jack, then most TVs will not have the channel scan option available.
Next, the only L2614XW02 I've found is a version of the Maxent MX-26X3 TV. This TV only has an analog tuner. Very few analog OTA stations are still broadcasting and those that are use low-power transmitters. Thus you have to be close to the signal source to receive the broadcast. For most stations, you'll need an OTA digital to analog tuner converter box. Similarly, if you have cable and use a set-top box, that will not be a signal that the TV will tune in directly. Use the set-top box to search for channels.
I hope this helps.
(Note: the tuner can be damaged by a surge that came through the antenna. My household lost a converter box and a TV following a nearby lightning strike. If this is the case, you may need to replace the TV or at least the main board.
