Sony has released a new firmware update to address critical video and audio malfunctions affecting several Bravia television models. The patch, version v114.602.170.1, targets issues like Dolby Vision black screens and HDMI eARC synchronization errors.
The MediaTek Pentonic 1000 chipset connection
The software malfunctions specifically target Bravia models utilizing the MediaTek Pentonic 1000 chipset. According to the report, this includes a wide range of devices from the Bravia 5 and Bravia 7 to the Bravia 8, Bravia 9, and the flagship Sony A95L. These errors were originally introduced through faulty firmware versions v114.603.050.1 and v114.602.080.1.
Sony has instructed users experiencing these issues to check for the latest software update and install it manually . The hardware-specific nature of the bug suggests that the interaction between Sony's custom software and the MediaTek chipset is the primary point of failure.
Black screens and eARC audio lag
Users reported that while native Android TV applications functioned normally, connecting external hardware caused immediate disruption.. Specifically, when a game console or media player was activated, the audio via HDMI eARC would fall out of sync with the video. As the source notes, this lag can ruin the home-cinema experience, especially when using high-end soundbars or AV receivers.
Beyond audio synchronization, the faulty firmware caused significant visual disruptions. Viewers have reported encountering black screens during Dolby Vision playback and seeing scan-lines appearing across the display. These glitches effectively neutralized the premium features of the Bravia lineup.
Why version v114.602.170.1 isn't a total cure
While Sony released version v114.602.170.1 to rectify these errors, the patch has not been a universal success. The report indicates that several users are still encountering audio dropouts when using eARC-connected external sources. Furthermore, some customers have reported significant video glitches when attempting to watch content encoded in Dolby Vision, suggesting the "bug fix" may have introduced unintended side effects.
Sony's technical support team has even suggested that the firmware may be incomplete. Although the company has officially labelled the update as a "bug fix," there is growing concern among the user community that the patch is merely a temporary measure rather than a permanent resolution.
Criticism of Sony's delayed Japanese support response
Sony's delayed response and initial silence on its Japanese support website have drawn criticism from the enthusiast community. This incident highlights a growing tension in the high-end home cinema market, where software stability is as critical as panel quality. Compared to competitors who often deploy rapid-response patches, Sony's slower turnaround has left premium owners feeling vulnerable to software-induced hardware failures.
Will Sony's engineers resolve the remaining eARC dropouts?
Several critical questions remain regarding the long-term stability of the Bravia lineup. it is currently unclear whether the persistent audio dropouts are a result of the new v114.602.170.1 firmware or an inherent limitation of the MediaTek Pentonic 1000 chipset's integration. Additionally, because the company's own support team has flagged the patch as potentially incomplete, users are left wondering when a truly stable solution will be deployed.
