Try disconnecting power cord for ten minutes, and connecting back. That should reset the TV to default settings.

Is this an LCD, Plasma, DLP or CRT television?

This sounds like you have trouble with the powersource or flyback on your television, they usually are a couple of hundred dollars to replace.

Hi, post the direct TV remote # and the box model # so I can lookup the info for you. you probably already know directTVs remote programming is built into the menu (codes and all).
You did not mention if the DT remote powers the TV on or off?

Check your TV seelected correct input source

Depends on how many things you are trying to hook up but if you are going from cable box or dvd player to your tv all you need is the HDMI in most cases as this will carry the audio and the video over the HDMI cable. You may have to double check/adjust the settings on your tv and/or the cable box/dvd player.
Thank you,

Okay most settop direct TV boxes go into a coaxle connector in the back of your TV witch then your Tv would need to be on channel 3 make sure channel 3 is detected by autoscanning for it or undeleting it if its been deleted but make sure the direct tv box is on and running.

If you have them on the scant connectors make sure you on the right input on your TV control there should be a input button press that to scan through to find your direct tv box!

I hope this helps!

This set should have a digital tuner.. If it is more than 3 years old it could still be using an anolog tuner.

You can only receive clear qam signal. If your cable company scrambles all available channels then you need decoder to receive cable tv

This could be a lot of things.. You did not post the model number of the television but you may have interference from other devices in the home and it the remote is not infrared then you may have stray radio waves causing problems.
