We didnt have a surge protector on our tv we

Look at the power supply module, most of them will have a surge protection devices (called MOV, same as used in common surge power strip but cannot handle big surge that power strip can handle) installed to protect minor surge, it should blow the fuse. Once MOV blown, it will more likely stay short circuit, if you put the new fuse in it will blow the fuse right away. You need to see if the MOVs blew up any sign of blown up components.
