I have an Hitachi Projection TV 43UWX10B. When I turn the unit off, the picture goes off, but the red light stays on and you can hear that it has not completely turned off. This has happened once before and I was able to correct the situation, but I forgot what I did.
If it is any comfort, my light has been on since I posted this and the TV has not burnt out yet.
I HAVE A SURGE PROTECTOR ON THE SYSTEM I TURN IT ALL OFF FROM THERE ALL DAY TODAY AND STILL THE SAME ISSUE ACCURS I DO HAVE ONE OF THE SMALL INDICATOR LIGHTS INSIDE THE UNIT THAT DOES NOT COME ON AT ALL .ITS A GREEN LIGHT NUMBERED DP23 I HAVE LOOKED FOR FUSES AND ONLY CAME ACROSS ONE SO FAR WITH THAT PANEL OFF IAM GONNA TAKE THE TOP COVER OFF AND LOOK THERE TO SEE IF THERE IS ANYTHING I CAN SEE WRONG IF NOT I GUESS A REPAIR MAN WILL BE OVER .
Try to unplug it for awhile like all day or do like i have and get one of those really cheep christmas light remotes and put it in line to turn off power and then every time that you turn off your set if the light dose not go out just turn off the power or have a repair man replace your power switch for alot of $$$$$.this work well for my system.
