Basic checkpoints on screen issues (Lines/Blurred/Odd colours) from the Audio/Video device

The following shows you solutions if you experience issues when connecting a TV and an Audio/Video device via an analogue cable (composite or component cable) or HDMI cable.

  2. Check if the cable is firmly connected to the TV and the connected device
    There may be a case that audio/video does not output from the TV correctly if the cable connected to the TV and the A/V device gets loose from the terminals.

    Replace the currently used cable then check if the situation will improve.
  4. Connect another input terminal of the TV and check whether the input terminal on the TV causes this issue

Press the Input button on the TV's remote control then switch the input method to the one that corresponds with the input terminal that you connected in step 1, and check whether the picture appears on the TV screen.
  5. Connect another A/V device to the TV and check whether the connected A/V device causes this issue
    If you have another A/V device, connect it to the same input terminal of the TV as the original A/V device then check whether the picture appears on the TV screen
