It is important to note that these are just some of the common causes of lines on an LG TV screen. If you are unable to identify or resolve the issue on your own, it is recommended to seek professional service or contact LG for warranty coverage.

LG TV Warranty and Coverage

When purchasing an LG TV, it is important to understand the warranty and coverage that comes with it. LG offers a standard warranty for their TVs, which typically covers manufacturing defects and malfunctions for a specific period of time. The exact terms and duration of the warranty may vary depending on the model and region.

What Does the Warranty Cover?

The warranty provided by LG usually covers any defects in materials or workmanship that occur during normal use of the TV. This includes issues such as dead pixels, screen burn-in, and faulty components. If any of these problems occur within the warranty period, LG will typically repair or replace the TV free of charge.

How Long Does the Warranty Last?

The duration of the warranty can vary depending on the model and region. In most cases, LG offers a one-year warranty for their TVs. However, some high-end models may come with an extended warranty of two or more years. It is important to check the specific warranty terms for your TV to know exactly how long you are covered.

What is Not Covered by the Warranty?

While the warranty provided by LG is comprehensive, there are certain situations and damages that are not covered. These can include physical damage, liquid damage, unauthorized repairs or modifications, and damage caused by natural disasters or accidents.

Extended Warranty Options

In addition to the standard warranty, LG also offers extended warranty options for their TVs. These extended warranties provide coverage beyond the standard warranty period and can offer peace of mind for a longer period of time. It is worth considering these options, especially for high-end TVs or if you plan to keep your TV for an extended period.

Standard Warranty Extended Warranty
1 year 2 or more years
Covers manufacturing defects and malfunctions Provides coverage beyond the standard warranty period

It is important to weigh the cost of the extended warranty against the potential benefits and risks. Consider factors such as the reliability of the TV, your usage patterns, and the cost of repairs outside of warranty when making a decision.

Preventing Lines on LG TV Screen
