Hi,
Looking at a diagram of the back of your TV I see that you have only one Coax input. You will need to plug either your antenna or the DirecTV in one of the other sources available on the back of the TV.
According to DirecTV's website, their box also uses composite video cables and depending on the age of that box, may have an HDMI connection also.
Looking at the back of your TV, the composite video cable input is the top two rows to the right of the Coax input you are currently using.
Once you have both connected to different inputs, you can use your remote to switch between the sources and watch whichever you like.

Usually you need a decoder to receive "Cable" With your "Cable" usually you connect the Cable antenna, to the Cable "Box" form the "Box" to the Audio Visual EXTERNAL inputs, in the back of the TV. Now IF your TV can receive the "Cable" directly, then you would have to connect the Antenna, into the rear of the TV, now you would go to the "Tuning" section, and, the TV, would automatically "Search" for any available channels. They would then, be displayed at the end of the scan. Please find a user manual below, this will help you tune in, IF you can. If you cannot, you will have to get a cab;e "Box" and a remote. Hookup to the TV, from the "Box" to the TV, via, Audio and Video cables. You use the "Box's" remote to change channels and volume. You first must set the TV's Volume, & picture setting, the TV, is basically just used as a "Monitor" for the "Box". Hope this helps..

What to do if you have an all snowy picture (blue screen or the TV displays unusable signal-no signal or no sync)
1 – If you are using a digital cable box or satellite receiver (make sure it’s on) and be sure your TV is set for either CH3 or CH4 (which ever you usually view it on). If you usually view it through video inputs (video1 or 2 etc.) make sure the appropriate input is selected.
If you still don’t get a signal see if you get picture using the DVD or VCR (if available) if you do than plug the satellite or Dig. Box temporarily into the place of the DVD (unplug DVD) you may have to use some A/V cables (RCA yel./red/wht like the ones on the DVD) to hook to the tv from the sat./dig. box. If you get a signal then the sat./dig box is ok. If not the Sat./dig box is not sending a signal and is either defective or needs to be rebooted (unplug wait 5 min try again).
2 – If you are using standard cable or antenna (source) if possible check that the source is good by connecting to another TV. Otherwise try running the source into a VCR and then out to the TV using video inputs (RCA yel./red/wht like the ones on the DVD) and then selecting the appropriate input. Try seeing if the VCR plays using standard CH3 (or CH4)
If the VCR plays on video input but not when connected to CH3 (CH4) then the tuner of the TV may be defective – see if you can use the VCR to change channel using the VCR remote.

BEVERLYQC::
How do you " accidently erased all my chanels " from a tv??
Was the TV connected to a 'cable box' ?
Was the TV conected to 'air waves' or antena input.?
If the TV is attacned to a cable box, temperly remove the cable box INPUT wire, attache an antenna to the IMPUT AND AUTOSCAN WITH THE REMOTE CONTROL
If the TV cannot 'autoscan' in 'air wave' reception...goto menu and set input channel to ch.3 or see if there is a switch in the back that can change to ch.3 or ch.4

You should get all the 'air wave' chanels which will include ch.3 & ch.4

Usually one connects a RF [cable tv, Dish tv, antenna ] cable to the INPUT of VCR & a RF cable output to tv (antenna )INPUT .The reason is that if you are watching TV reception (Cable, Dish, etc) and you want to watch VCR tape, just push the tape in and it should start playing picture.
From what I understand that you are trying to say:: [ YOUR NEW TV ! ] you MUST connect to the RCA jacks, CABLE S with RCA plugs that come out of the VCR to the new TV [ INPUT & OUTPUT] jacks .When you ["" use input botton on VCR remote"" ] you are using a DIFFERENT input signal. You are not letting the TV know that you are changing the signal from RF(antenna, Cable, Dish,etc)to the RCA signal ["" I use my input botton on my vcr remote""]

Hey wegodsky,

If you're not able to find the right channel on your TV to use your DVD player, you may want to try changing the TV's input source instead. Many TV models will require that the TV be set to an external antenna in order for any other device (like a VCR or DVD player) to function correctly. This can usually be done by pressing the menu button on the TV itself and selecting an option similar to "Input," "Source" or "Antenna" if you do not have a remote control for your TV.

Hope this helps you out.

Sincerely,
Aaron

Was an auxillary input accidently selected? Try selecting inputs to see if this straightens it out. What model set do you have?
