Just received a pair of 3100e/40's. One seems ok, the other will boot ok
but after about four minutes the screen will freeze and the keyboard will
become completely inoperative.
Turning it off and on results in three or four bright vertical lines on
the screen and no other activity. Turning it off for twenty minutes or so
results in it booting up normally as above.
Does anyone have any suggestions as to where to start?
