LG Simplink Not Turning Off Sony Blu-Ray Player - Smart Home | digitalhomefaults.org

Technical Background:

Simplink leverages the HDMI-CEC protocol for inter-device control. The LG TV acts as the controller, sending power commands to connected devices like Blu-ray players. Failure indicates a break in the CEC communication path, a misconfiguration of CEC settings on either device, or firmware incompatibility. Power consumption profiles of both devices are normal in standby, but the Blu-ray player fails to enter low-power mode upon TV shutdown.

Symptoms:

Blu-ray player (Sony) fails to power off when LG TV is powered off via Simplink. No error messages displayed on LG TV. Blu-ray player remains powered on, LED indicator solid blue. Attempts to power off Blu-ray player via LG TV remote (Simplink function) are unsuccessful. CEC (Consumer Electronics Control) appears inactive.

Possible Causes:

HDMI-CEC disabled on the LG TV or Sony Blu-ray player.
Incompatible HDMI cable version (older cables may not fully support CEC).
Firmware incompatibility between the LG TV and Sony Blu-ray player.
Incorrect HDMI port usage (some ports may not support CEC).
Interference from other devices on the HDMI bus.
Power fluctuations affecting CEC communication (common during Canadian winter power grid stress).

Solution:

1

Verify HDMI-CEC (Simplink on LG, Control for HDMI on Sony) is enabled on both the LG TV and Sony Blu-ray player via their respective settings menus.
2

Use a high-speed HDMI cable that supports CEC. Replace existing cable with a certified HDMI 2.0 or higher cable.
3

Ensure both the LG TV and Sony Blu-ray player have the latest firmware installed. Check for updates via the devices' respective network settings.
4

Try connecting the Blu-ray player to a different HDMI port on the LG TV. Refer to the TV's manual for designated Simplink-enabled ports.
5

Power cycle both devices: Unplug both the LG TV and Sony Blu-ray player from the power outlet for at least 60 seconds, then plug them back in.
6

Disable any other devices connected via HDMI to the LG TV temporarily to rule out HDMI interference.
7

Check the Bravia Sync settings on the Sony Blu-ray Player. Change them to default, then re-enable after power cycling the devices.

Safety Warning:

Do not attempt to disassemble or repair the LG TV or Sony Blu-ray player yourself. Doing so could void the warranty and create a risk of electric shock. Ensure proper grounding of all connected devices.

Prevention:

- Regularly check for firmware updates for both the LG TV and Sony Blu-ray player (at least quarterly). - Use high-quality HDMI cables that support CEC. - Periodically power cycle the devices to clear any accumulated errors. - Ensure stable power supply using a surge protector, especially during Canadian winter months.

Expert Tip:

Some LG TVs have a hidden Simplink menu. Try accessing it by repeatedly pressing the 'Info' button on the remote while on an HDMI input. This may allow for more granular control over CEC settings.
