The only reset is to unplug the power to the TV for a minimum of 2 minutes then plug it back in and retry

You can use a brush to clean the inside and look for any bits or pieces of component in the board. if so this will indicate the component and the relativity to the POP noise. It can be a capcitor shorting and bursting or even a transistor that has popped. The fuse being blown is due to a failure and it can be SHORT in the board. You need to use a multimeter to probe the +B and trace the short, Isolate the sections and it will lead to the shorted ccomponent.
