The manufacturer confirms this model’s platform. The menu steps below follow the manufacturer’s platform instructions; check that they match the software on your TV.
Troubleshoot with your model
Model code: 55R5D5CA. Source market: Canada. Match the whole code, including its suffix and generation, with the label or model information on your device.
Your model is preselected when you open the 3D guide. Also select the other device’s model if you use a separate audio system.
Start with these checks
Play something and check volume
Play a scene with speech. Cancel mute and raise the volume a little. If you use a TV box, check its volume too. Check whether sound is being sent to connected headphones.
Does sound return? Replay the original programme and keep the audio output that worked.
Compare TV speakers and the audio system
Temporarily select the TV’s own speakers in its sound menu if offered. Listen to the same scene. The menu name and path depend on the model and software.
Do the TV speakers work? Check the audio system’s input and connection. If the TV is also silent, compare sources in the next check.
Compare programmes and sources
Try another programme and a built-in TV app if available. Compare with your TV box or HDMI player. Note which sources produce sound.
Is only one source silent? Check that source’s audio track, volume and output. If all sources are silent, run the model’s built-in sound test if its manual documents one.
Check the connection you are using
For a separate audio system, compare the socket labels with both manuals and select the matching audio-system input. Switch devices off before changing an accessible cable. Let any update finish first.
Does a TV app work while the external player does not? Check the player’s connection and audio format. Change one setting at a time so you can identify what helps.
What is confirmed about this model’s connections?
- Documented connection: HDMI eARC. Model source
- Documented connection: optical audio. Model source
These facts apply to the documented model variant. Check the other device’s connections and supported formats too.
Restart or reset?
A normal restart and a factory reset are different actions. Follow the model’s restart instructions and replay the same source. Wait for any software update to finish before disconnecting power.
- Open Settings → System → Power → System restart. If Power is absent, select System restart directly under System. Confirm the restart and wait for the TV to start again.
Manufacturer restart instructions
The guide’s separate reset procedure may erase personal settings. Check the exact model and source market, record your settings and read what will be erased before confirming. A sound test or normal restart does not require a factory reset.
If the problem remains
Note the full model code, purchase country, selected source and input, cable type and which checks produced sound. Include any error message or indicator pattern. Manufacturer support can then continue from your results.
