I have a Fujitsu 42" plasmavision TV that is connected to my computer. It keeps shutting off and flashing red light after only seconds of turning on. The problem has gotten worse as it uses to stay on longer before shutting down. When I first hooked it up I didn't have this problem at all and now I'm lucky to get 5 seconds of power. I am running other things like my computer, printer, etc on the same power source and wonder if its not getting enough power? Before I have an electrician come in and run a new power source I wanted to know if anyone has had this same problem and how it got fixed? I can't help but to wonder if its the power source why it used to work fine? Please help!
