I'm not sure what part you're talking about, but the User Manual has a diagram. Unfortunately, the ifixit bots are marking my link as spam, so I can't post it here.

Try a new/different HDMI cable and a different TV if that doesn't work. That will eliminate the cable and TV as parts of the problem.

If the tablet is brand new but an older model, you will probably have to wait for google play to update itself. Once it does, it will update everything else and it should be fine.

Try a recovery disk if you have one. Alternatively, you can make one yourself. Personally, I use a program called Hiren's Boot CD to do diagnostics when anyone is having trouble booting. You can actually make it work on a thumbdrive. I would show you a link but ifixit bots are not letting me for the time being. I am not all that familiar with Macs, but there should be a system diagnostic called S.M.A.R.T. that you can utilize to determine if your hard drive is going bad. I will tell you, though, that more than likely your hard drive is failing after ten years.

Do you have a bluetooth device connected?

Download a temperature monitor for your laptop. If it is overheating, try blowing out the heatsink, usually located right where the fan blows out. Do you only notice this problem while running on battery?

Make sure your sound settings are not turned all the way down. Since you removed your volume buttons, you should be able to change it in settings.
