I just bought a new dynex 32 inch DX-32L152A11 tv. I tired to hook it up to my dish system and the picture is black and white and no sound.

i dunno but mine is doing it and i have only uad it for 1 year

You need to replace the inverter board thats what preventing the backlights from lighting up so you can see the picture. You can get the inverter board from www.tvrepairworld.com

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.)

With a Black and White picture it sounds like you're trying to connect the DVD Player's "Composite" connection to the TV's Component Connection.

Composite is a 3 wire system with Yellow for the video, and red and white for the audio. On your TV this connection is located on the side.

Component is a 5 wire system, with Blue, Green & Red for Video, and Red and White for audio. On your TV this connection type is located on the rear panel.

Check to make sure you are hooking the DVD player & the TV to the same input types.

You can get the user manual for this unit from this link, just click HERE

it only for tv update for firmware

I have a DX LVD33 power light is red and no picture or sound screen is black. Please advise.

if you are useing componet output and the pic is black and white you have them hooked up in the wrong order
