Sony uses BRAVIA Sync, BRAVIA Link and Control for HDMI names for supported HDMI-CEC control. Compatible equipment can share selected power, volume or playback commands. Check the exact models, ports and device list; one working command does not establish that every remote action or media format is supported.
Write a command and device list
Record the Sony TV, external player and any receiver or soundbar in the HDMI chain. Include the port connections and remote in use. Then identify the required action: power, sound level, player transport or movement inside an app. These should be tested as separate commands.
Use the manuals for the actual models. Sony’s overview notes that menus and even required ports can vary. A modern route through Channels & Inputs should not be copied into an older Watching TV or External Inputs interface solely because both sets carry the Sony name.
Check the supported HDMI control route
Confirm the relevant HDMI control setting on compatible equipment and inspect the TV’s model-specific BRAVIA Sync device list. Verify the named target rather than relying on an input’s generic label. Keep the original settings recoverable before a comparison.
If a soundbar sits between the player and TV, include it in the record. A volume command reaching the soundbar can be useful even when a player’s app navigation needs another supported remote action. That difference is evidence about control routing, not proof of a broken picture connection.
Compare commands independently
Use an idle state and ordinary controls; do not interrupt an important device task.
| Action | Expected recipient | Useful observation |
|---|---|---|
| Volume up/down | The chosen TV speaker system or soundbar. | Record which device changes level. |
| Power | The intended linked equipment. | Record each device’s response separately. |
| Basic play/pause | The selected supported source. | Check the source’s documented transport support. |
| Directional movement | The external player’s active menu. | Record whether its focus moves. |
| Home or settings | The device assigned that remote action. | Identify which interface actually opens. |
Retain the limited conclusion
If one command succeeds and another does not, record both. Avoid describing the whole connection as working or broken from a single observation. Use the original device remote as a baseline where its normal controls are available.
The expected result is a known supported command relationship or a model-specific question about one command. CEC success does not certify resolution, HDR, audio decoding or account access. If a required control remains unavailable, ask Sony and the external-device publisher about that exact model pair and command rather than applying a universal reset or protection-bypass recipe.
