The conclusion of this: I called Planar, I gave them the serial number
and from that they knew who bought the monitor. Fortunately, it was only
about halfway through the 3-year warranty. I did not have to send any
documentation to them. They sent me a replacement by 2nd-day FedEx and I
shipped the broken monitor back in the same box at no cost. The last
tech I spoke with thought it was a dead backlight.

So far, the replacement works fine.
