To connect your Sony DAV-DX155 to a television, use an HDMI cable. Connect one end of the HDMI cable to the HDMI OUT port on the back of the DAV-DX155 and the other end to the HDMI IN port on your TV. Select the correct HDMI input on your TV to receive audio and video signals from the DAV-DX155.
Check if the speakers are properly connected to the main unit. Ensure that the speaker wires are securely inserted into the correct terminals. Also, verify that the volume is not muted and is set to an audible level. If the problem persists, try resetting the system by unplugging it for a few minutes and then powering it back on.
To reset the Sony DAV-DX155 to factory settings, turn off the system. Press and hold the STOP button on the main unit, then press the POWER button while holding the STOP button. Release both buttons and the system will reset to its factory settings.
Currently, the Sony DAV-DX155 does not support firmware updates via the internet or USB. Ensure that your system is functioning properly and check Sony's official website for any support bulletins or updates.
First, ensure there is power to the unit. Try pressing the OPEN/CLOSE button on both the remote control and the main unit. If the tray still does not open, turn off the system, unplug it, wait for a few minutes, and then plug it back in and try again.
To enhance audio quality, ensure that your speakers are placed correctly according to the listening position. Adjust the surround sound settings on the remote control and consider using higher quality audio cables or optical connections for better sound fidelity.
Ensure the DVDs are clean and free of scratches. The Sony DAV-DX155 may not play certain DVD formats or region-coded discs that are not compatible with the system. Refer to the user manual for supported disc formats.
To set up the radio, extend the FM antenna and connect it to the FM ANTENNA terminal on the back of the main unit. Use the FUNCTION button on the remote to select "FM" mode. Use the TUNING +/- buttons to find the desired radio station.
The Sony DAV-DX155 does not support Bluetooth or USB audio connections. However, you can use an auxiliary cable to connect the headphone output of your smartphone to the Audio In ports on the back of the system.
Regularly dust the exterior with a dry, soft cloth. Avoid using liquid cleaners. Periodically check and tighten speaker connections. Ensure that the ventilation slots are unobstructed to prevent overheating. Keep discs and the disc tray clean to prevent playback issues.
