Stopped working after 16 months

I received this monitor from Dell. It did not come with a stand, which needed to be purchased separately for about $300. It was working fine and then suddenly stopped displaying a picture, stopped responding to the remote control power switch, stopped responding to the standby switch on monitor. The monitor is 16 months old, has been plugged into an APC UPS surge suppressor and only has one video cable plugged into it. I was told by Planar that they would replace the unit for $1600. I would not recommend purchasing anything from Planar.
