We currently have a Norcent LM 730. It has been working fine until last week. Now when you turn on the computer the monitor comes on but doesn't say on. The power is on and the monitor displays an image for a second and then goes black. I checked all of the wires and connections and they are fine. After turning the monitor on and off about 10 times, it comes on and works fine. Can you let me know if this is a common problem or if there is something that I can do to fix it. My email address is m6a2r7k5@hotmail.com. Thank you for your time.
