How to recognize damage in a television? The most common symptoms and their causes.

Posted by           Guide  

Modern televisions are technologically advanced devices that offer excellent picture and sound quality. Unfortunately, even the latest models can fail. For many users, this means the need to purchase new equipment, but in many cases, the problem can be solved by replacing the appropriate part. In this article, we present the most common symptoms of faults in televisions and their potential causes.

1. The television does not turn on

This is one of the most common problems reported by users. If the television does not respond to the remote control or the buttons on the casing, the problem may lie in:

  • The power supply – damaged capacitors or other components may cause a lack of power in the device.

  • The fuse – a blown fuse may block the power supply.

  • The main board – in extreme cases, it is the main board that requires repair or replacement.

2. No picture, but sound works

If the television emits sound but the screen remains black, the problem may concern:

  • LED backlighting – damaged LEDs are a common cause of no picture in modern televisions.

  • The panel – although rarer, a panel failure can cause a lack of vision.

  • T-Con (Timing Control Board) – damage to this board can lead to issues with displaying the image.

3. Stripes on the screen or distorted image

Vertical or horizontal lines appearing may indicate:

  • Panel damage – this is the most common cause of such problems.

  • Signal cable issues – damaged or loose cables may disrupt the signal transmission to the panel.

4. The television turns off by itself

If the device turns off without a clear reason, it is worth checking:

  • The power supply – it may be overheating or lacking power.

  • The software – outdated or faulty software may cause the device to reset.

  • Sensors – damaged temperature sensors may cause unnecessary shutdowns.

5. No response to the remote control

Problems with the remote control may arise from:

  • Dead batteries – this is the simplest but often overlooked cause.

  • Damaged IR receiver – it may need to be replaced in the television.

  • Software errors – resetting the television or updating it may solve the problem.

How to approach the repair?

Before starting the repair, it is worth:

  1. Diagnosing the problem – make sure you know which part is causing the failure.

  2. Ordering the appropriate parts – use trusted suppliers who offer compatible components.

  3. Using a guide or service – if you lack experience, it is worth seeking help from a specialist.

Why is it worth repairing the television instead of buying a new one?

Repairing a television is not only a way to save money but also an eco-friendly action. Replacing damaged parts instead of throwing away the entire device helps reduce electronic waste and extend the lifespan of the equipment.
