My Dynex tv keep saying scan channel

If it is asking for zip code you have not told it to scan for over the air or antenna channels when it asks air or cable

The first time that the TV is activated, it expects to have to search for either over-the-air channels or CATV channels. Obviously, the ROKU is coming in on one of the Aux inputs, but you'll still have to run the scan just to get it out of the way.

for some reason it is not seeing you cable signal. you will need to make sure you have it set up for cable and not air. check your input options, like tv/av/hdmi/ ect hope this helps

you need to select cable from off your remote and run the auto scan.even if it says you does not need to run auto scan still run the auto scan.good luck.

Which Dynex TV do you have? The manuals for most Dynex TVs are available from the product page. Start at http://www.dynexproducts.com/products/televisions.html . If you have an older Dynex that isn't on the main list, check under Discontinued Products. Alternatively search for your model. Then click on the Support tab to find the manual for that model.

For at least one Dynex TV (DX-32L152A11), the procedure to scan for channels is below.
To scan for channels, first make sure that the current input is set to TV. (Press the input button on the TV or the remote). Then press Menu and use the left/right arrows to select TV. Then press Enter or down arrow (the manual says the right arrow). Use the up/down arrows to select the entry to change. First, make sure that the Tuner Mode (first item) is set to Air (use the left/right arrows to change this). Press Menu to go back to the TV menu. Then go down to Channel Scan and press Enter. You may need to confirm the channel scan and press Enter again. Wait for the scan to be completed.

On a discontinued model (DX-32L151A11), the procedure is slightly different. With the input set to TV, press Menu. Select the Channel submenu and press Enter or down arrow. Set the TV mode to Antenna (use the left/right arrows to change the value). Then press the up/down arrows to reach AutoScan. Press Enter. Move cursor to highlight Yes and press Enter again. Wait for the scan to be completed.

I hope this helps.

(There were some Dynex monitors built. They usually do not have a coaxial antenna in port since they didn't have tuners.)

okay lets do a cable check... cable from wall /outside connected to cable box in, from the cable box out to (please note any DVD recorder or VCR should be connected here if you have and then on to TV) TV in ..... TV on , turn to channel 3 (this should be the only ch locked on the TV no scan is needed) you are using coaxial cables... if this was/is a hi def connection (your set should be on component)

Excuse me but the other answers are written by people who have not actually confronted the problem and are just guessing. They are all wrong. Here's the answer:

If your TV is expecting a TV input, it will keep searching for at least one TV channel on cable or antenna. If you only have a DVD player plugged in, for example, or if your cable is hooked up wrong, so there's no video signal on it, the TV will keep searching forever. (This is an unforgivable design flaw, by the way. But then, it was a cheap TV, wasn't it?)

To solve the problem, look at your remote control. You will find input buttons. Mine are small, along the top, right under the "power" button. Try pressing "video" for example, instead of TV. That stops the TV from hunting for TV channels.

Have a merry Christmas. Enjoy your new TV. Watch it in moderation and eat fruit and vegetables every day.

What you have to do it go to the TV Menu and go to channel. Then go to channel scan and do one of those. THe problem is that is just doesnt know where to look for channels, but a quick scan will fix that.
