I plugged a Popcorn Hour A-110 into the HDMI port of my Vizio L32 last weekend and at first it worked, but then it stopped. Now with anything plugged into the HDMI port the unit powers itself off after a few seconds. Without anything plugged in the screen stays blue. Since this happened if I switch to the digital tuner (DTV) all I get is a blue screen. I used to use it to display my over the air digital stations when my satellite went out. I've tried going into the setup menu for both inputs and do a reset. After doing the reset for the DTV, if I try to select the 'TV' option the menu disappears and I'm back at the blue screen.
All of analog, RGB, and S-video ports all work fine.
What do I need to fix the digital portion of the TV?
