Question about Hitachi UltraVision CineForm 55VG825 55" HDTV
You are correct about lamps working or not, but that is the extremes. Over the course of operation all lamps lose brightness as the hours add up. All lamps will lose their brightness over time.
Typically lamps only last at best 6000 to 8000 hours. That is not long if the unit is used most of the day everyday. In addition the cheaper the quality of the lamp, cost and manufacture, the quicker they go down hill.
Assuming that you have a low quality lamp what you are experiencing is normal. You may be able to improve the brightness and clarity of the picture by cleaning the lenses, mirrors and screen. I have a tip at
This tip is labeled projection tv but is also appropriate for cleaning an LCD or DLP unit.
