Dynex dx-32l151a11 the picture is black and white with the dvd player

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

You need 3 RCA plugs... generally colored red, white, and yellow. on the back of the DVD player plug the yellow to video out, the red to audio out (stereo), and the white to audio out (mono). The other side of them goes to the back of the TV... the yellow video input 1, the red audio (R) input 1, the white Audio (L) input 1. Then take the cable service round coax cable and screw it into the back of the DVD unit where it says Coax. Get another short coax cable and hook to back of the DVD unit on Cable out, and the other side to the back of the TV under cable/vhs. And that"s it! Hope that helps you!

You will need to get a HD receiver box. Your tv supports upto 720P so a HD box that is set to 720P should work just fine. You should connect it via HDMI . As for your second question does the audio be like that even when you are using other input source such as a DVD player?

The main set up is that you need to set your PC video resolution to the native resolution of this TV in PC mode otherwise the pictures will look real bad and not clear. No driver needed.
To use the TV as a monitor will not be as good as the PC monitor due to limited resolution the TV can display.

first rotate and secure all of the RCA plugs (red, yellow white) if that doesnt work, if there is a coax in the equation, it is not screwed in proplerly.

First, there is no such thing as a 'universal' remote, even the 'learning' remotes will not learn from every original remote. Second, for anyone to help you, you need to post both model numbers, the player's and the remotes.
Generally, if a remote is only even a little older than the player, it may not contain the code set for the player.

Make sure the cables are pushed on all the way. I've had a similar problem.

Sadly that happens with all rechargable batteries...they eventually lose their holding capacity
