Chosen Solution

I blew a fuse and replaced it with the same type. When plugging back in, heard a pop and it now reads E9. The board inside shows Resistor 1 to appear toasted and and more black evidence around a multi leg connector. I can’t find schematics and can’t read the value of the resistor–any ideas?

This multiprong connector had evidence of burning on the other side. Is this a component or just a junction? I would like to test it.

if u zoom all the way in it almost looks like the numbers are 4731
