    The tv does not seem to be able to find any over the air signals during channel scan. Could the tuner be defective?

Try checking the signal strength then run the scan again.
Checking the DTV signal strength
You can check the DTV signal strength to determine if you need to adjust your antenna or digital cable input. The higher the signal strength, the less likely you are to experience picture degradation.To check the DTV signal strength:
1.Press MENU. The on-screen menu opens.

2.Press < or > to highlight Channel, then press v. The Channel menu opens. The DTV signal strength is shown at the bottom of the menu.

3.Press EXIT to close the menu.

Finally bought anRCA antenna for my new Dynex TV.Nothing no signal,no way to scan for channels I can see.AGGH.Is it a lemon?


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.)

Dynex TV losing favorite channels


Try changing the batteries in your remote. If the batteries are weak they may not be sending strong enough signals to the TV thus sending different signals than you meant.

Need code for Dynex/DX-l42-10A for Dish Network


I know you've probably figured this out by now, since you posted last May, but I figured I would post the solution, since I just found it, and someone else may want to know.
I bought one of these sets the day after Christmas 2009, and finally figured out the code that works with the Dish Network 5.4 IR remote.
I did a Code Scan, and found that the code that works is 721. In the Dish Network listing, this is listed as the third code for Sansui.

Hope someone finds this useful, even if it's too late for you.
