Thank you, Ken. But I am in big trouble. If you can help, please do, see my post at:

Basically, the light is gone and the top right corner of the page is no longer touch-sensitive (e.g. I can't come out of Settings screen except via reboot).
Should I do factory reset? I doubt it will solve anything.... Any ideas?
