What kind of connection are you using to connect the TV to the laptop, S-video or PC(VGA)?
Did you try to extend the display? To do so, press and hold the Fn key, press the F8 key simultaneously. You may have to press the combination keys several times to get the desired result.
Also, you can try to change the input source on the TV depending upon the cable connected. You can refer to the Owner's manual for Panasonic TX-32 LXD.
You can also refer to the Owner's manual for Latitude D630 for your reference.
Do write back with the information.
Thanks and Regards,
