We have a Zennith Z42PJ240 Flat screen plasma TV that just powered off and we are not able to turn back on. It died only 1 year and 2 months of having it. We bought it without a warranty plan; we thought it would last us for several years. The question is: What can we do to power it back up? Without having to wait 2 weeks for a Sears technician to come out? Please help us. Lisa Hancock 928-634-0123
