Question about ViewSonic VA721 17" LCD Monitor
1) To unlock the monitor: http://www.fixya.com/support/r4554177-viewsonic_monitor_lock_unlock
2) I am not sure about the red light, are you taking about the power light or you are getting red tinting cast on the screen.
3) The monitor is old will more likely to have problem in the power supply by now due to bad caps and it can make the monitor act strangely. I am not sure what you mena by loos power cable.
I would not suggest you to try to take it apart since there are high voltages inside that can kill you.
