When you turn on your TV and hear a “click,” it can be a concerning sound. This noise, often accompanied by a black screen or picture problems, can indicate several issues. Don’t panic! This article will analyze the possible causes of that clicking sound and guide you through troubleshooting steps.
Decoding the Clicking Sound
That “click” is often the first sign of trouble with your television. But what does it mean?
- Power Supply: A loud “click” when powering on usually points to a power supply problem. It could be a faulty capacitor, a blown fuse, or even the power supply unit itself.
- Backlight: A quiet, repeating “clicking” sound during operation, especially in LCD or LED TVs, might indicate a failing backlight.
- Relays: In older TVs, a “click” can also come from a faulty relay, responsible for switching between different components.

Causes and Solutions for a Clicking TV
Pinpointing the exact cause requires investigation. Here are some DIY steps:
1. Check the Power Supply
- Outlet: Ensure the TV is plugged into a working electrical outlet.
- Power Cord: Inspect the power cord for any damage or fraying.
- Surge Protector: Use a surge protector to prevent damage from power surges.
2. Check the Backlight
- Screen Test: Turn on the TV in a dark room and shine a flashlight at an angle onto the screen. If you can faintly see an image, the backlight is likely faulty.
3. Check the Relays
- Locate the Sound: Try to pinpoint the source of the clicking sound. If it’s near the power supply, a faulty relay could be the culprit.
