The results of this investigation are unequivocal: edge-lit TVs are inherently prone to significant durability issues, including warped reflector sheets, cracked light guide plates, and burnt-out LEDs due to concentrated heat. These problems manifest after prolonged use at maximum brightness, posing a significant risk to their long-term reliability.

we recommend prioritizing models with better heat distribution, such as direct-lit or FALD TVs, for improved longevity and performance.

Excluding the 18 OLEDs, which have burn-in from constantly streaming CNN, over 25% of the 82 LCD TVs in our test suffer from visible uniformity issues.
It gets worse if we look at LCD TVs by their sub-type. Seven out of the eleven (64%) edge-lit models in our test suffer from uniformity issues, one has outright failed, and others are in the process of doing so. In contrast, only 14 out of the 71 (20%) full-array local dimming (FALD) and direct-lit TVs have uniformity issues.
