How do you switch input modes on a samsung without a remote control?

I have a Samsung TV and when i turn it on it goes straight to input mode. I was wondering if there is some way to get the TV out of input mode. I tried to use my universal remote but I don't think that it will work while the TV is in the input mode. Does anyone know some buttons I can push to get it in the regular mode?|||It sounds like one of the manual buttons may be stuck in and is constantly pressing on the switch behind it. Press each one in one at a time to see if they all move freely and if the switches feel like they are working right. Most Samsung sets have an input button on them and that one is probably stuck in.
