Last week my iPhone X fell off the couch (Mexican jumping bean?). It had an Apple Case on and landed screen side up, but I was confronted with one Fluorescent Green bar on the screen. I restarted and now I have 4 such Bars, one with a little bit of pink. In the current crisis, it's hard to find an authorised Apple repair shop. I tried to do a hard reset, but it wouldn't do it, nor would my Mac recognise the phone when tethered. My suspicion is that there is a loose connection rather than a screen issue. Can anyone confirm this and give me an idea of repair cost? A good guide is the US price which will translate roughly into £'s or Euros. I attach a photo, although the lines show as white rather than the green to the human eye.
