OLED TV Owners Report Green Mist Defect Amid Repair and Refund Claims

Reports are emerging of OLED televisions developing noticeable colour discoloration across portions of the screen, rather than a single uniform defect.

While commonly described by owners as a “green mist,” “green haze,” or “green spot,” the issue often presents as uneven colour distortion that becomes especially visible on certain tones, including yellow, pink, and red.

Some consumers report being refused warranty repairs after retailers classify the screen discolouration as burn-in rather than a manufacturing defect. In these cases, customers are sometimes incorrectly told they must prove the defect existed at the time of purchase.

By adding their experience as a documented case or report, affected owners contribute to a growing body of shared evidence showing consistent symptoms across multiple devices. This aggregation alongside information provided by LG confirming that the discolouration is not caused by burn-in has helped demonstrate that the issue is systemic rather than isolated or user-caused.

Affected Models

LG has confirmed that the screen discolouration, often described as a green mist, is a known issue and not caused by burn-in. In affected cases, it has been treated as a manufacturing defect and covered under warranty.

Here is a list of TV models with cases and reports.

Consumer protection laws in several countries may also apply. In some jurisdictions, retailers are legally required to repair, replace, or refund products sold with manufacturing defects, regardless of whether the product remains within the manufacturer’s or retailer’s stated warranty period. In the UK, consumer rights may extend up to six years from purchase, while in Scotland the period is up to five years. Guidance for other regions, including the EU and US, is still being clarified.

Possible Causes

OLED panels are known to be sensitive to temperature extremes. While the display panel itself generates limited heat, internal components within televisions can produce uneven or excessive heat, which may contribute to display abnormalities over time.

Broader OLED Concerns

OLED technology offers superior contrast and color performance but is also subject to material degradation over its lifespan. As organic compounds age, brightness and color accuracy can decline, making OLED displays more vulnerable to permanent image retention and burn-in. These risks are particularly pronounced in scenarios involving static on-screen elements such as channel logos or game interfaces.

Consumers who believe their television may be affected are encouraged to add their experience as a which will be documented as a case or report. Each submission helps build a clearer picture of how widespread the discolouration issue is, strengthens the shared evidence available to other consumers, and supports efforts to challenge incorrect classifications and warranty refusals. As more cases are recorded, the combined documentation improves visibility of the issue and increases the likelihood of fair outcomes for affected owners.
