I have a Sharp Aquos LC-46LE830U tv that I've had for many months and my xbox was able to control it perfectly fine. Now, all of the sudden, it refuses to control it, meaning I have to use the remote. I tried manually setting it up but it doesn't know my model number even though I punched it in exactly, and it also worked before. I don't know what is going on.
When I set it up automatically, it detects my tv very quickly and shows a remote code, but it still cannot control it.
