I have a RCA Scenium DLP. Thursday, the picture was frozen on the screen. Tried to turn the tv off. The TV would not respond. Tried the buttons on the front and the buttons on the remote - no response. Wound up unplugging it to get the power to shut off. Left it unplugged for the day. When attempting to turn the tv back on - still have no picture - no sound. The Blue lights on the front panel of the TV come on - stay solid. No picture or sound at all. Buttons still do not respond. Any suggestions welcomed. Thanks
