someone help me get out of it? have a Sanyo LCD 900p tv. Model number DP-19648. I had my computer connected to it and after making a cake it was in standby mode and I can't get it out of it i tried move the mouse i changed the channel to my dish network receiver and I can hear the audio but no video and the green light is on. I don't have the money to buy and new one or bring it to a repair shop. I unplugged it and plug plugged it back in an hour later and its still in standby mode
