Sony BRAVIA Update v114.603.100.1: What Actually Changes?
A TV update is easy to ignore when everything works. When dialogue falls behind the picture or your sound system starts acting up, that same update suddenly becomes a lot more interesting.
Sony BRAVIA firmware v114.603.100.1 has a September 15, 2026 release date on Sony's U.S. support pages. The official description is brief: general performance improvements. That leaves owners with practical questions about compatibility, audio problems, and whether to install it.
The quick answer: Check your exact model and current firmware before updating. Sony's U.S. notes do not promise a universal HDMI/eARC fix, and some older software versions require intermediate updates.
Information checked September 24, 2026. This guide focuses on U.S. owners and Sony's published documentation; it is not a hands-on firmware test.
What Does Sony BRAVIA Update v114.603.100.1 Change?
Sony lists “Improves general TV performance” as the current benefit. It does not provide measurements or a detailed breakdown of those improvements.
Read the longer changelog carefully. On the BRAVIA 7, 8, and 9 update page, My Cinema, Direct Connect support, and several picture and sound fixes appear under Previous Benefits and Improvements. Those are carried forward from earlier releases.
Our reading: treat this as a maintenance update. The release notes alone are not evidence of brighter HDR, faster gaming, or a new picture-processing upgrade.

Does It Fix Audio Delay, Lip-Sync Problems, or eARC Dropouts?
A complete fix for every audio problem is not confirmed by the U.S. changelog. There is relevant official context, though.
In a September 2026 notice, Sony Japan acknowledged HDMI lip-sync errors and popping or other audio noise after an earlier software update. It said a September update was planned to improve lip-sync, while investigation of the noise problem continued.
That notice concerns Japan and does not identify v114.603.100.1 as a universal solution for U.S. sets. It also does not establish that every sound dropout has been resolved.
Listen for the specific problem: Dialogue arriving late, brief silence, and audible crackling are different symptoms. Improvement in one does not prove that the others are fixed.
If audio is your reason for updating, repeat the same movie scene or gaming session afterward with the same source device and sound system. A quick menu check will not tell you much about an intermittent problem.
Sony Japan's HDMI audio notice provides the regional background.
Which Sony TVs Can Install This Update?
Compatibility follows the full model number and region. These are examples explicitly listed on the Sony U.S. pages checked for this article, rather than a complete model list:
| TV family | Listed model examples |
|---|---|
| BRAVIA 7 | K-55XR70, K-65XR70, K-75XR70, K-85XR70 |
| BRAVIA 8 | K-55XR80 |
| BRAVIA 9 | K-65XR90, K-75XR90, K-85XR90 |
| A95L | XR-55A95L, XR-65A95L, XR-77A95L |
| BRAVIA 7 II | K-50XR70M2, K-55XR70M2, K-65XR70M2 |
| BRAVIA 9 II | K-115XR90M2 |
Use the applicable-model list on the BRAVIA 7/8/9 page, A95L page, or BRAVIA 7 II/9 II page to verify your set.
BRAVIA 5 and BRAVIA 8 II also appear on Sony's Asia-Pacific release page. U.S. owners should confirm availability through their own model's U.S. support page or TV update menu. Do not use a different region's download as a shortcut.
Check Your Current Firmware Before You Start
Press Input on the remote and open Help; the software version appears below the model name. If Help is missing, Sony says to add it through Edit in the input menu.
For the older North American models covered by Sony's prerequisite instructions, the update path is:
- 114.602.050.1 or later, but below the target version: install v114.603.100.1 directly.
- 112.634.100.2 up to, but not including, 114.602.050.1: install 114.602.050.1 first.
- 112.602.120.1 up to, but not including, 112.634.100.2: install 112.634.100.2, then 114.602.050.1, then the new release.
For anything older, follow your model's support instructions or contact Sony. Do not assume this sequence applies to every BRAVIA family. If you already have v114.603.100.1 or a newer version, you do not need this installation.
How to Get the Update on Your TV
For automatic update notifications, Sony gives this route: Input → Help → Status & Diagnostics → System software update → Automatically check for update. Skip Status & Diagnostics if it is not displayed.
Automatic availability is staggered, so the TV may report that it is up to date before the new firmware reaches it.
Prefer a manual installation? Follow Sony's USB instructions for your exact model. Extract the outer download and place its three contained files in the USB drive's root directory. Allow up to 30 minutes for installation.
During installation: Keep power connected and leave the USB drive in place. The TV may restart as part of the process. Check the software version after completion.
What to Test After Installing v114.603.100.1
Give the update a fair comparison. Our suggested checklist keeps the focus on how you actually use the TV:
- Replay a familiar dialogue scene. Look for a mismatch between lip movement and speech.
- Use your usual HDMI source. Test the console, streaming player, or disc player that showed the problem.
- Compare built-in apps with that external source. Note whether the symptom happens in both.
- Keep the session running. If trouble previously appeared halfway through a movie, test for a similar length of time.
- Change one setting at a time. Record the starting setup so you can make a meaningful comparison.
If the problem remains, give Sony your TV model, installed firmware, source device, soundbar or receiver model, and the steps that reproduce it. “Audio slips out of sync after 40 minutes on this HDMI source” is more useful than “sound is broken.”

Should You Install the Update?
Our recommendation is to install the officially offered update for your exact model after checking its prerequisites. Schedule it when you have time to test your normal setup afterward, especially if you rely on an external sound system.
Keep expectations practical: judge the result by the problem you wanted solved. A firmware number on the Help screen confirms installation; it does not tell you whether an intermittent audio issue is gone.
At TelevisionCafe, our advice is to save a quick record of your current settings and symptoms before you begin. That gives you a useful starting point if you need further troubleshooting.
Sony BRAVIA v114.603.100.1 FAQ
Will the update erase my settings?
Sony says personal settings are retained. Photographing any carefully adjusted settings is still a useful precaution.
Can I roll back if I dislike the update?
Sony's official instructions do not allow installation of an older software version. Contact support if a problem appears afterward.
Should I change all my sound settings after updating?
Our suggestion is to test your existing setup first. Changing several options immediately makes it harder to identify what helped or caused a problem.
How should I report a remaining audio issue?
Describe the symptom precisely, list the connected equipment, and explain when it occurs. Include whether built-in apps behave differently from external HDMI devices.
