Thank you so much for your comment.
I think I'll check this out as soon as possible.
from what you're telling me, it should help me figure out if the Xbox died due to some other problem, or if the switch plate (or flat cable) is the culprit. In that regard, I just ordered the ribbon cable with the plate and connector.
