I purchased a Sony XBR 55X930D televison in July 2016.
Recently I have been receiving a message which states "No signal.Check the external input or select another input using the INPUT button". Input is correct (HDMI 1).Usually this problem self-corrects within 24 hours(no action taken by me) but it has been occirring more frequently in the last month. I have changed no settings/cables/connections on the TV and there is no apparent reason for this issue . Resetting the TV did not correct the problem.
When this message appears, I can still use the internet functions on the TV but cannot watch any cable channels
I welcome suggestions on how to address this annoying problem
Welcome and thank you for considering the SONY Community!
We regret to hear about the issue you currently have. To isolate the issue, kindly refer to the steps below:
Check which input on the TV the source device is connected to.
Using the supplied remote of the TV, press the INPUT button repeatedly until the correct HDMI input is displayed.
NOTE: The location of the Input button on your remote and the Input labels may be different on your TV.
Disconnect and reconnect the HDMI cable.
A bad connection may occur temporarily and cause this issue. Follow the steps below then check if the situation has improved.
Turn off all the devices.
Disconnect the HDMI cable from the HDMI Input terminal on the TV.
Disconnect the HDMI cable from the HDMI Output terminal on the connected device.
Reconnect the HDMI cable firmly to the same terminals as it was connected on the TV and the connected device.
Turn on the TV and the connected device, and turn them off. Then turn them on again to let the TV recognize the connected device.
Check if the input of the audio system (such as amplifier or theater stand) corresponds with the video output device when the video output device is connected to the TV through the audio system.
: Video output device (Example: Blu-ray Disc/DVD player)
: Audio system (Example: AV Amplifier)
Make sure the connected device is set to output through its HDMIconnection and the video format being output is compatible with the TV.
NOTE: The output signal set on your source device may be indicated on its display or in its menus.
Some devices may output a 1080/24p or 1080/30p video signal, but some TVs can only accept a 1080/60p video signal. Changing the video output format of the connected device may resolve the issue. Check the manual or contact the manufacturer for further information about changing the video output format.
When connected to an A/V receiver using an analog connection type (Coaxial, Composite A/V, Component A/V, or S-Video), the receiver may not be able to up-convert that signal to HDMI to send to the TV. Refer to the operating instructions included with your A/V receiver for more information on other connection options.
If the device is connected to an A/V Receiver or other component before being connected to the TV, try connecting directly to an HDMI input of the TV. If this works, your receiver or other device may not be an HDMI repeater and might not pass the signal on to the TV.
NOTE: An HDMI repeater receives an audio/video signal from one HDMI device and passes it through to another connectedHDMI device. While Sony® products are supported for use with HDMI repeaters, products from other manufacturers may not be supported.
Power reset the TV and the connected device.
Try using a different HDMI cable.
NOTE: To view 1080p (50p/60p) quality picture on the TV from an external device, use a High Speed HDMI cable with the "HDMI" logo as the connection cable.
If possible, try a different device that can output an HDMI video signal using the same connections.
