I'm having the same problem, and in my frustration I must state that this piece of hardware has never worked to my satisfaction. Since I first picked it up I've experienced problem with it. Powering it on sometimes takes several atempts, I have to unplug the powercord and wait a couple of minutes before I can power it up again. How can this problem occur out of the blue??? I havn't used the projector for a while (3 weeks) and now when I tried to power it up I took a closer look on it and all the buttons where blinking .... And I cannot get it to start. Does anyone have a solution? And how is LG's service, I really don't want have my projector sent away for several weeks. Please post how you all solved this problem!!
