Hi, i have a pokemon yellow cart, i polished and cleaned it with a mars eraser and the contacts look great.

but the game still just shows a blank screen after the nintendo logo and the beep.

so i looked at the pcb and noticed that on C5 there is no resistor, but on all the other locations there are.

is there supposed to be a resistor there? how do i know what strenght?

right now it is just 2 solder points.

any ideas?
could this be the problem?

if the battery was dead wouldnt it still come up?
