Arghh..
I received by PA271W a week ago. When I first tried to power it on---nothing. Disconnected and reconnected the power cord to no effect. Swapped power cords from another monitor and ,aha, it worked. Took the power cord (that I thought was defective) and connected it to the known working monitor and it worked...sigh. Took that cord and reconnected it to PA271W and the it seemed to be happy with that cord. Maybe a faulty connection originally, I don't know. Happily used my monitor for a few days but this morning I try to power it on and---nothing. I go through the cord switcheroo again, but still nothing. I call my vendor, Other World Computing and they happily set up an exchange.
I'm getting ready to pack it up disconnecting everything and decide to try it one more time---and it works.
I'm still doing the exchange. Why am I sure they'll fire it up just fine when they receive it?
