KlikyA TV that changes volume or channel by itself is receiving commands. Take the batteries out of every remote: if it stops, a button is stuck. If not, turn off HDMI‑CEC and unplug HDMI devices one at a time. If it continues with nothing connected, the TV’s own button is faulty.
1. Rule out the remote
Remove the batteries from the TV remote, and from any streaming, soundbar or cable remote nearby. Wait a few minutes.
- It stopped: a button is stuck or the keypad is dirty. Press every key firmly a few times, clean around the keys with a cloth dampened with isopropyl alcohol, and test again. If it comes back, the remote is worn out.
- It continues: the remote is innocent. Go on to step 2.
A quick way to test infrared in general: put a strip of tape over the TV’s sensor window. If the problem stops, something in the room is sending infrared, such as a second remote wedged in the sofa or a neighboring TV’s remote of the same brand.
2. Turn off HDMI‑CEC
HDMI‑CEC lets connected devices control the TV: a console waking up switches the input, a soundbar changes the volume. When one device misbehaves, the TV appears possessed.
| TV | What CEC is called | Where |
|---|---|---|
| Samsung | Anynet+ | Settings › General › External Device Manager |
| LG | SIMPLINK | Settings › General › Devices › HDMI Settings |
| Sony | BRAVIA Sync | Settings › Channels & Inputs › External inputs |
| Roku TV | 1‑touch play, System audio control | Settings › System › Control other devices (CEC) |
| Vizio | CEC | Menu › System › CEC |
If turning CEC off cures it, turn it back on and unplug HDMI devices one by one to find the one responsible.
3. Phones, voice assistants and routines
Anyone in the household with a remote app, an Alexa or Google routine, or a casting app open can change the volume or wake the TV without meaning to. Check the smart-home routines that mention the TV, and the TV’s list of allowed devices.
4. The TV’s own button
If the menu opens or the volume moves with every remote disabled, CEC off and nothing plugged in, the button or joystick on the TV is shorting. Unplug the TV for two minutes first. If the problem returns, it needs service; on some models the button panel can be disabled in the settings as a stopgap.
Control the TV while the remote is in pieces
- Install Kliky from the App Store or Google Play.
- Connect your phone to the same Wi‑Fi as the TV.
- Pick the TV in the list and confirm on the TV if it asks.
