Channels won't come in
These are a few things I want you to check first.
1) Make sure the cable set top box is on and the cable is connected to the TV properly (This may seem simple but I have had to charge many people a $60.00 service fee plus a $70.00 travel fee just to turn on a cable set top box)
2) Make sure the TV is set to the proper input you are using (RF( F connector) , HDMI, Component video, and or Composite Video)
3) Make sure the TV is set to the proper channel (either channel 3 or channel 4 depending on your area) The cable set top box should be action as your tuner.
If all of these conditions are met, then we can begin troubleshooting.
First determine if the other inputs work (HDMI, Component video (RGB), Composite video (yellow), s-Video (6 pronged black cable).
If the inputs work then you possibly have a tuner problem
If the inputs don't work then then problem is likely in the video microprocessor.
If the problem is in the tuner or the connective circuitry then we will have to determine where to get a replacement tuner (or you can just use one of your other video inputs)
If the problem is in the video section (which includes the microprocessor) we are going to have to troubleshoot the video section which will involve you having a background in electronics, if not I would suggest having a qualified TV technician perform service on this TV.
I hope this helps,
