My brother’s xbox does not appear to work, any recommendation?

I don't actually onto this website, however I would like some assist with my brother's xbox. Couple of weeks earlier than he went to school, my sister was cleansing and taking stuff out of his room so she will make hers. When it was time to maneuver the xbox, I'm guessing she didn't maintain correctly or one thing, however she should've have finished one thing accidentally (so I heard, I used to be downstairs taking part in video video games or one thing). Anyhow, when my brother tried to play a sport on the Xbox, no video was taking part in on the TV. The Xbox does appear to activate however nothing is proven on the monitor nor TV. In my assumption, I believe there may be an issue with the HDMI. Clearly, he was mad because it brought on round 500 to get one. I let my brother have my xbox whereas the one he has stays right here. There's two choices of how this is able to go; both my sister will get him one other Collection X for breaking his (she has a job), or we attempt repairing it which I'm making an attempt to do however I'm probably not good relating to restore. I used to be considering possibly pay somebody to restore however I don't know who would I’m going to. With all that out of the best way, I simply needed to know if anybody know what's occurring with my brother's xbox and the way I can repair it. Thanks and have a great day. (I’ve some photos of the xbox and the again. I attempted taking a greater image of the HDMI, you can too see that in one of many photos the xbox being on however nothing on my monitor)
