That's just some careful trial-and-error, you'll be fine.

While you've got the display off and the motherboard out, I recommend tightening and using loctite on all the screws that connect the handle, those loosen rather easily. If you've got the skills, I also recommend this. A rattling handle is annoying. My friend Tod's handle actually squeaks as it rattles and I keep telling him I'll fix it for him if only I he'd let me get my mitts on the player for long enough.
