How do i change the input
The 27" TV uses the same instructions as the 20", and I found the manual for you at the link below. Answering your question directly, here is the section of the instructions about changing input:
Changing the TV's Input
Normally, your TV displays the signal coming through the antenna terminal. However, if you've connected another component to your TV(such as a VCR & DVD) using the Video/Audio input,you will want to be able to view the signal from the component.To do this, you will need to switch from the ' TV ' input to the 'AV1-AV3, CVI' Input, as follows.
1 With the TV on, press the MENU button twice, then " Set-Up " menu will appear.
2 Use the WCHV buttons to select " Input ".
3 Press the CVOLB buttons to change the input source from ' TV ' to 'AV1, AV2, AV3, CVI'.
4 Wait 20 seconds, or press DISPLAY button or MENU button to return to normal TV viewing.
* CVI means the Component Video Input (Y/ PB/ PR) from the DVD player etc.* Users can also select these input modes with the TV/AV button or the INPUT button on theremote controller.
* On the AV1 mode , if you connect the S-VHS jack to your TV, "AV1" is changed to "S-VIDEO".
