Weird eject issue and device control not working

So this is actually two separate issues:

1. I am having a strange issue with my One X where the eject button is intermittently not working, but when it is not working, the disc will eject if I push on the front of the top of the case. I would assume there’s some shorting issue going on, does anyone know what part I would need to inspect and/or replace to fix it?
2. When I received my X back from being repaired by Microsoft, I noticed that the device control feature no longer works. It didn’t bother me enough to send back again for another 2-3 weeks, so I figured now that I have the time I’d fix it myself. It worked before and I used that feature to turn my TV on and off with the Xbox, and now it is not working. It will say that it has recognized the TV and can control it, but it doesn’t actually work. I have tried it with several TVs to the same result, so I know it is an issue with the Xbox.

If anyone has any insight on either of these issues, I would greatly appreciate the help. Thank you!
