I have an Element ELEFT502 50 HD Digital tv. I am trying to connect my cable line to the TV but cannot get the past the auto scan screen

Where is your antenna hooked up? Thru a cable box? Direct to tv? Completely describe setup, maybe post photos

try going to settings ,menu then hit present or auto scan

Connect the TV to the Comcast box using an HDMI cable, then set input on the TV to HDMI - that's all. You then select channels on the Comcast box , not the TV (although the TV remote can be programmed to change channels on the cable box)>

Check it by making a hard reset. Unplug the TV from AC mains wall socket, and re-plug it back after 10 minutes or so. This must make it a hard reset. If this do not help you, check and replace it system control memory IC. It is faulty. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock! Instead, contact the nearest service center.

Make sure you have a good connection from antenna to TV. Check antenna and cable and cable connection to TV. Select DIGITAL button on TV remote when wanting HD channels. Remember HD channels are always digital. Also, any given TV station may not be broadcasting in HD at a given time. They can broadcast in digital but in standard definition sometimes. Your TV has a built-in DVB-T tuner. Try executing a channel scan to pick up all available channels. On-screen menus go to Digital Setup, then Digital Tuning, you can auto-tune or manual tune channels. The TV should take a few min. to scan thru available channels and store the channels its finds. Check with anyone in your area to see if they get HD channels (it is possible to be outside of the range of some TV stations) Your TV is a 2006 model and should still be compatible with local digital TV broadcasts but keep in mind digital signals could change in the near future (DVB-T2) and you may need a tuner/converter box to make the TV compatible.

unplug the tv and the direct cable box reset the box by plugging both the tv and box back in. MAKE SURE the tv is set on the right input for the box first. if the tv said to do auto scan then you lost the connection from the box either by changing the input that box is connected to if by a cable its usually 3 or 4. if by hdmi or rca cables its an input channel. also make sure not cables are loose try that first before unplugging the tv let me know

Your TV probably does not have a digital tuner connected to the DTV/ANT input. Mine didn't. I had to connect the digital antenna to a digital converter box THEN go to the DTV/ANT input. Only then would it activate the DTV menu and allow me to scan for channels. If your TV worked fine with Cable TV connected to the input, it was because your signal was coming from the digital tuner in your DVR, or your cable provider was sending you an unscrambled digital signal (not likely).
I used a digital converter box I had purchased with the government $40 coupon back in 2009 but the resolution is only 480 and looks like a Monet or Renoir. Now I am shopping for a high quality tuner.

Hello, the HDTV input is what you would use if you were not using a cable box.
You should connect your cable from the wall to coaxial input on the cable box, and connect an hdmi cable from the hdmi output on the cable box to the hdmi 1 input on your tv and then switch the tv to that input.
