Firmware v114.602.050/080 breaks Dolby Vision and HDMI eARC audio on Bravia 8 II
The Bravia 8 II is explicitly named among models hit by Sony's v114.602.050.1 / v114.602.080.1 firmware: Dolby Vision playback failure, audio desync worsening over time, and complete audio dropouts via eARC. Sony's fix v114.603.100.1 was rolled out to US owners, but the article states UK and European owners were still waiting — directly relevant to this EU-market subject.
What to check. If buying an 8 II in the EU, check the installed firmware version before relying on Dolby Vision/eARC; the buggy v114.602.x builds shipped in 2025 and the European fix lagged the US one.
Vertical white line at center of Bravia 8 II OLED panel; Sony swaps TV rather than repairing panel
An owner reports a ~1-pixel vertical white line at the center of a Bravia 8 II panel; a reply states Sony does not repair or replace panels but swaps the whole TV (new or refurbished) at its discretion. This is a panel-level defect with a replacement-only resolution path.
What to check. A vertical line on the panel is a hardware defect; Sony's policy is to exchange the whole TV rather than repair the panel, so a buyer should act within the warranty/return window (14 days online in the EU) rather than wait.
Falling scan lines visible in Dolby Vision on Bravia 8 II after firmware v114.602.050.1
The thread title names the Bravia 8 II specifically; the OP reports falling scan lines in dark Dolby Vision scenes after the v114.602.050.1 update, present regardless of gradation settings. Other owners confirm the same on the 9 II and A95L, pointing to a firmware-introduced artifact rather than a per-unit fault.
What to check. A visible picture artifact in dark Dolby Vision scenes that appeared after a specific firmware update; buyers should be aware it may be present on current firmware and is a software artifact, not a panel defect.
Live-TV stuttering/judder on Bravia 8 II after firmware 114.602.030.1 / .080.1
Two owners of the 8 II (K-65XR8M2 and K-55XR8M2) report persistent motion judder/stuttering on live terrestrial TV after the 114.602.030.1 / 114.602.080.1 firmware updates, with streaming unaffected. This is a firmware regression specific to the 8 II model codes.
What to check. Live-TV motion stuttering appeared after a specific firmware update; owners report workarounds (changing channel, Motionflow tweaks) but no clean fix yet, and Sony support had not marked it as a known post-update issue.
