Question about Astar LTV-3201 32 in. LCD Television
32 inch astar 1080i lcd keeps having invalid input pop up which then leads to the tv switching to standard mode (channel 8 for example). Then I have the hd button to go back to whatever channel I was watching at the time. This problem occurs every 5-20mins and is also accompanied by the volume bar popping up right before the problem occurs.
I have the same problem in the office, but, not at home. I believe the IR sensor is confused by office florescent lighting, which has an unperseptible 60-cycle flicker not charactoristic of home incandescent lighting. Energy saving compact florescent probably have the same effect.
I have attached a dark tube over the sensor with relative success. This cluge is an unfortunate compensation for poor engineering because of the reduced angle of reception (the remote has to be directly in front of the sensor).
