SOURCE: TV IS NOT RECEIVING SIGNAL FROM LAPTOP
Check graphic card software on laptop to make sure it's on the right settings to output image to TV.
SOURCE: I have a LG 47Inch
On the LG remote, push the "netcast" button, which is between Menu and Q.Menu.
You need to have a Netcast account set up at Netcast.com
SOURCE: My LG LCD TV
Is it going one way - channel 1-2-3-4-5 bottom to up or any way at random. Find out which way and check the channel button on the TV to see if it is stuck.
SOURCE: how to stream media from macbook pro to lg smart tv
From what I can see, there is no way to stream to this TV from any computer. You'll most likely have to buy an adapter cable to allow you to connect your Macbook Pro to one of the HDMI ports of the TV.
SOURCE: Problem with remote control or TV sensor? (Sanyo lcd32xr8da)
From your detailed description, I assumes that the infrared sensor inside your TV has the fault. This part can be loacated just behind the infrared sensor window at the front panel of the TV. You have to open the TV, and desolder it out from position, note the type used, and repalce it. There are so many types of these. Pictures of some are attached here.

Hi Peter Carroll, we want to help you with your question, but we need more information from you. Can you please add details in the comment box?
No signal for what ?
Does DTV signal not found mean when on source DTV if so- check antenna cable plugged into antenna socket on TV
and cable is plugged into wall socket that goes to antenna on roof of building .
make sure cable used is for TV RF signal rather than a video cable as they look identical but are different in electronic characteristics you need 75 ohm coaxial cable designed for radio frequency signals.
