Can you use a 5 amp fuse instead of a 4 amp fuse in a television?

I have never seen a 4 amp fuse, only 3 and 5. The peak power draw and dump is when you switch on and off your TV. Try a 3 amp and if it blows when you turn it on, then no, your particular TV can't use a 3 amp fuse. Don't worry about this test, it shouldn't damage the TV and fuses cost so little.
