Following the release of firmware version 1710 for the Samsung QN90B (2022 Neo QLED 4K TV), a subset of users across forums (Reddit, AVSForum, Samsung Community) reported that their TV runs noticeably hotter than with previous firmware versions (e.g., 160x, 150x). The heat is often described as radiating from the back panel, particularly near the top-center and One Connect Box connection area (on models with external box). Some users reported thermal shutdowns, though not widespread. Samsung has not officially acknowledged a heat-related issue in release notes.
