Can not control volume or mute or turn on or off tv with any remote controls
Sounds like the infra-red sensor inside it is either damaged or it do not get proper voltage to work. Check it. If it get proper voltage/s and still not receive any infra-red signal from the remote control, replace it. The part in discussion will look somewhat like this.
Prior the replace this component, make sure that the remote control you're using works properly, and do emits infrared light rays, during each button presses on it. Check the remote control for its infrared emission. Check it with fresh batteries. If you wish to get more details about how to check a remote control, please visit this site. One among the posts has details about it. Surf the site with patience.

SOURCE: Remote volume control for Sharp Aquos 42inch LCD not working
User 'rapolley' is absolutely right. One can cycle through the functions to access different options, ie. 'TV', 'Audio', 'DVD', etc. I stumbled upon this solution when I thought my 'Menu' button wasn't working. All I had to do is cycle through the 'Functions' and choose 'Menu' once I get to 'TV'. Thanks!

IN THE GOOGLE SEARCH ENGINE TYPE VIVITEK V37835 MANUAL. ONCE YOU GET THE MANUAL LOOK IN THE SECTION OF THE MANUAL THAT SAYS SETUP CODES FOR SATTELITE RECEIVERS. FOLLOW THE INSTRUCTIONS FOR PROGRAMMING UR REMOTE. ALSO WANT TO LET YOU KNOW THAT I HAVE DISH SATTELITE AND I USE MY VIVITEK REMOTE NOT THE SATTELITE REMOTE FOR MY PROGRAMMING. MAYBE TRY THIS. IT WORKS FOR ME.
