I bought a LC-37D62U 2 months ago. Recently just realized the volume and channel control on the TV is not working. If I try to change the volume or channel on the TV, it displays the INPUT select option instead. What's wrong?

This problem very common in sharp tv.The POWER,OPC flashes.First turn on have power LED indicator light stable at all? Tries the power again couple times will have backlight come back on,than it will work.Not at all more than 5-6 times than ur main turner signal board is the problem,must replaced.
Your dish remote should be set to the code for your TV. Then you will be able to control the channel number, not just up/down, as well as volume and maybe even the input. But do try to get a real remote for your TV so you can get to its menus.
Meanwhile, use menu+menu to see the channel being output by the Dish receiver. (Must be a 622/722... based on the 60 you listed.) Try to find an unused UHF channel number that your set does have in its up/down list. Match Air/Cable setting of Dish and TV. The Dish output is analog (NTSC) although the tuner(s) only accept digital (ATSC).
On some cable boxes they have their own volume control. Raise the volume on the box if you can. if the volume on the tv is up all the way it should be loud. It should not be the tv if you have volume already coming out. try hooking up a dvd player or some other device and see if you have the same result
TV is under warranty. Get a tech to look at it. It could require a new IR sensor, a firmware upgrade or a system reset that only a tech can do called an Industry Initialization that is in the service mode only
If you use a digital cable box, it could be that the volume on that isn't turned up all the way. I didn't even realize the box had volume controls until 2 years after I got it...makes a HUGE difference now
We had this problem with a 28PW6515. The control would work for 30 seconds after switching on, then nothing. It was diagnosed as the "glue chip" which handles all the control functions. About £200 to fix it as it's a surface mount chip.
