Diagnosis and Repair Guide for Pixel Burn-in on LG OLED65C24LA TV

SAFETY WARNING: Televisions operate with mains voltages (230V) and power board capacitors can retain lethal residual charges even after disconnection from the outlet. However, for the specific defect covered in this guide (burn-in), opening the back panel is entirely useless for resolution purposes. ReeFix provides this information for purely diagnostic and educational purposes, advising against disassembling the device.

Pixel Burn-in Diagnosis on LG OLED65C24LA

The phenomenon of "burn-in" (or permanent image retention) on LG OLED65C24LA TVs is caused in 90-95% of cases by the physical and irreversible wear of the LG OLED65C24LA OLED Panel. In panels with OLED technology (like the C2 Evo series of this model), sub-pixels subjected to prolonged static images (TV channel logos, video game HUDs, fixed interfaces) lose brightness faster than the rest of the screen, creating a "ghost" image.

It is extremely rare for the defect to be attributable to a malfunction of the LG OLED65C24LA Main Board or the LG OLED65C24LA T-Con Board, as failures of these boards usually generate dynamic artifacts, sharp vertical lines, global color distortions, or a total absence of signal, not static printed images.

Quick diagnostic checks:

1. Pixel Cleaning: Access the WebOS TV menu (Settings > General > OLED Care > Pixel Cleaning) and run the manual cycle. This function realigns pixel voltages. If the ghost image persists after the procedure is complete, the damage to the organic diodes is permanent.
2. Uniform Color Test: Play (for example, via the TV's YouTube app) a burn-in test video containing solid color screens (red, magenta, yellow, 10% gray). This will allow you to accurately map the extent and severity of the exhausted pixels.

Costs & Tools: Panel replacement on a 65-inch C2 series TV has a prohibitive cost, often equal to or exceeding the current market value of an equivalent new television. Although theoretical disassembly requires a set of precision screwdrivers, plastic opening tools, and an anti-static wrist strap, physical intervention is not recommended as it is not a solution without the main replacement part.

Operational Decision: If the "Pixel Cleaning" software function does not eliminate image retention and color tests confirm burn-in, we are facing permanent physical damage. Repair by panel replacement is uneconomical. The most logical solution is to tolerate the defect until viewing is acceptable, then consider replacing the entire television.
