Jvc lcd tv model lt-32ex19 video inputs are not working as well as tv channels doesnt appear only blank blue appears pls help

sounds like the remote batteries could be bad or the buttons on the remote need to be cleaned. some JVC TV remotes, I'm not familiar with this particular one though, can be cleaned using a clean pencil eraser. Be careful opening the remote because some parts can fall out or you can damage the connections to the LED emitter that sends the signal to the TV. Also the solder connections on that LED could be bad.

All LCD tvs HDMI cables support both video and audio.Tries another HDMI cable or tries another HDMI hub port on the tv.

On the right hand side of this television there are panel buttons. It appears that your son in law knocked the tv out of the correct input. Press the input button in order to cycle through the 5 inputs. Typically pressing the input button on the side panel of a television and pressing it again and again and again will make it change inputs. Universally the buttons on the tv panel function as follows: Channel up moves the cursor up. Channel down moves the cursor down. Volume + moves the cursor right. Volume - moves the cursor left.
Hope this helps

Seeing as it does not have a digital tuner in it, I would think this would be the problem, you will have to get a box for it.

Check the video cable coming out of the xbox, depending on which model xbox it is (arcade, pro, elite etc.) it will most likely have both component cables - green, blue and red or RCA cables - Yellow, red and white. It sounds as if your JVC would only be able to run RCA cables (due to its age) so use the yellow cable for video and white and red (or just white if you only have a yellow and white input) and then make sure the switch located on the cable is switched to "standard" and not "hi definition" hope it helps.

These are the codes printed in the owners manual for your dvd/vcr player.If they do not work you will have to contact Emerson and ask them for help getting the code. The contact number should have come with the instructions for the remote. Just give them the model number of you remote and the units model number and they should be able to help you. I hope this information helps you with your problem. Switch the input selector on your TV to an appropriate external input channel (usually near channel 0).
Press a button on the TV’s original remote control that selects an external input channel until the DVD
recorder’s picture appears. Check your TV owner’s manual for details.

faults & possible causes to LCD & Plasma screen are given with illustrations. You can get an idea about the fault to an extent. Faults to all LCD & Plasma screen are similar,

It sounds funny but, unplug the set for 30 seconds to allow the TV to reset then see if the problem still is there.
