Hi! I'm new here, and frankly, don't know much about plasma TVs. We just purchased a TH-42PD50U Panasonic 42" plasma TV, and after only having it for four days, it now won't turn on. The power light indicator keeps flashing on and off, and when we unplug it/plug it back in, try to turn it on, it makes a clicking sound, but no picture. The user's guide says nothing about this in the trouble shooting, and the Panasonic technical support center has terrible operating hours. Can anyone help? Thank you!!
