TV antenna finds no channels (or loses channels after a scan)

Most antenna problems are setup and signal, not a bad tuner: wrong input or scan type, a loose or damaged coax, an unpowered amplifier, an antenna in a poor spot, a splitter that cuts the signal, or a signal so strong it overloads the tuner. Stations also move or change format, so a rescan is the first step any time channels disappear.

TVs: standby LED blink patterns, why they are model-specific, and how to use them

Some makers use the standby LED as a self-diagnosis output. Sony, for example, repeats a group of blinks with a pause, and the count names a fault area. The meaning of a count depends on the maker and the chassis, so one model's table does not apply to another. Samsung's support simply says that if the red light still blinks after a power cycle on a known-good outlet, the set needs service. Use the blink only to separate power-delivery problems from internal faults and to point to a board.

TV talks: a voice reads every menu or describes the show

This is an accessibility feature that was switched on, often by accident through a remote shortcut (holding Mute or Volume, or pressing Star several times). A voice reading menus is the screen reader (Voice Guide, Audio Guidance, Screen reader). A voice describing the show is audio description, which may be a TV setting or the streaming app's audio track. Nothing is broken.

White or bright round spots on an LED TV (fallen backlight lenses)

On direct-lit LED TVs each backlight LED has a small plastic diffuser lens (often called a reflector) glued over it. When the glue fails from heat, the lens drops off and that LED shines straight through as a hot spot. It is a backlight hardware problem, not settings or a bad input. The fix is to open the panel and reattach the lenses or replace the LED strips; spots that spread over months mean more lenses are letting go.
