Hello, my name isXXXXX can assist you. As you have discovered, you really need a remote to access most of the Tv's functions. The first thing I would suggest is to figure out if your Tv is not responding to the remote's signal or if your remote is not even sending a signal.
It's actually pretty easy to test if the remote is sending a signal. All you need is a camera or camera phone. Point the tip of your remote into the lens of the camera, as if you were taking a picture of the tip of the remote. Now look at your camera's screen and start pressing buttons on the remote. You should see a blinking/flashing white light coming from the tip of the remote. That is the remote sending a signal. If you do not see any while flashing light on your camera screen then the remote is indeed not working. If that is the case then your best course of action is to purchase a new remote. You can go to your local store and get a universal remote but you will have to program it with a code to work with your Tv. Or you can buy an original Sony remote that will not require any programming, it will just work-click here to buy original Sony Tv remote
Now, if you actually do determine that your remote is sending a signal then there is actually a problem inside your Tv that will likely require a Tv repairman. If you have previous experience with DIY electronics repairs then we can actually help you here, so reply here if you want to attempt that.
Hopefully this is just an issue with your remote, in which case a replacement is your best bet. Please understand that I am here to give you honest and complete information. At least you are now informed of your options and you did not have to waste time and money on a repair shop.
