youre best bet would be to open the guitar up. look and see if you have any loose wires or connections. if youve tried different sets of batteries, is there a way to hard wire it to the xbox? if so try that.
if the battery has swollen up its bad, dont try to reuse it and properly dispose of it it could cause a fire or burn you if it decides to pop and explode. get your hands on a new battery and try to full charge it and use that. if it doesnt work after that post back up on here!
typically yes, is it the same style hard drive? you may need to format it properly for the Xbox to see it. if you dont it wont work at all and the xbox wont boot. there are a TON of guides on how to do this that can be found wit ha simple google search usually.
so first off, you bought it new ? just exchange it for new one! typically if you got it from a big chain place you should be able to exchange it no problem. if you cant then you will have no choice to open it. it honestly sounds like the screen ribbon cable is shorting out. best case its just dislodged from the connector. worst case is its sheered off and loses connection in that one position when you move it.

(1) try and inspect and reseat all connectors for video. (2) try using a different monitor \ cables (3) remove the power cord from your pc and try to reseat your ram and video card ( if applicable) (4) if you have multiple sticks of ram try removing them all except one and see if that changes anything. (5) try using other ports on the video card.
from the sounds of it youre on your own when it comes to getting this fixed. if you have any electronics knowledge this will be easier. if not a few google searchs i think youll be alright. start by opening the unit, im sure there are some phillip screws holding the out case together. then try to find the PCB and see if there are any obvious signs of dmg, burning , scorching, corrosion. things like that. also check to see if there is a fuse that may have blown. having a multimeter will DEFINITELY help with troubleshooting this. also post some pictures up on here to help with narrowing down the problem! good luck!
while the phone is SUPER robust odds are if it spent the entire wash cycle in the machine…. the odds of it not being pretty damaged are low :( really the only thing you can do your self is open it up and check the components on the phone from the sound of it there is probably more than one issue with the phone. do you have it backed up? it would only be worth trying to save if there is stuff on it that you dont have backed up. if so i hope you have insurance. honestly it would probably be cheaper to do it that way if you have the coverage.
