(You can tell it's the control pod and not the sound system itself.... I tried different combination) until I have a decent sound, with both speakers and subwoofer working. ... I think that you can manage to keep the volume control.
I had quite a difficult time trying to find the internet cable but I have an idea of something that might work. Check out a phoenix connector. If the spacing is right you could use those and regular speaker wire. But if you have to have the Bose brand interconnect I would try contacting Bose service Department. But get ready to pay over $70 for them. The Phoenix connectors are only $1.99. Hope this helps
If you only pull the plug out for 5 minutes this will have nil effect as most systems have a power battery that curves up during use and keeps setting etc during power cuts so until you unplug it for at least 24 hours which is longer than most power cuts the settings put in won't change and go back to factory settings
Looks like a problem with the lcdscreen I would take it to your nearest qualified repairer who may tell you how much anew LCD screen would cost to replace unless it is under warranty
You have something overheating and shutting down. You need to have knowledge of electronics to fix that, do you? You can feel the chips as it plays and see if any get hot. After that, you need some tools you probably don't have, and knowledge that you probably don't have to fix it. yourself. Take it to a repair shop.
