Does anyone know what this means.
Yesterday am my M92 was working fine. Came back to it an hour later to find a blank screen with a single black line. It won't turn on, or off (to be honest I'm not sure wether it is on or off). There is a continuous blue light. I plugged it into the USB on the computer and an orange light came on which turned to magenta a few seconds later. The disc doesn't mount on the desktop and nothing happens on the M92 screen. After a while the single line turned into 6 lines (not all at once - the additional lines have appeared slowly). If I press and hold the on/off switch the light does go out after about 15 seconds but comes on again after I release it.
I've used the reset button in the back and pressed the on/off switch, several times, after reading other posts. It hasn't had a knock or anything like that - I've just been using it on my desk at home.
I'm really worried I might have lost the work on there, which is quite a lot and there is a deadline for getting it done

( I know - should have backed it up).
I had a look on other posts and a blank screen with lines s been mentioned a couple of times in posts about other screen issues, so I am hoping this is something recognisable and fixable....
Does anyone have any ideas?
