Question about Hitachi 50V720 Television
What you are seeing is the degradation of hte "light engine". This is normal with extended use. You can try blowing out the area with compressed air to clean out any dust. But any LCD based projection system is subject to this breakdown over time. Can you further describe what you mean by overall picture quality? Is it out of focus? do you see separate colors (convergence problem)?

see page 59,60,61,62. The problem can be the lamp
After extended use, if the TV picture turns dark, the color looks unusual or LAMP INDICATOR light turns on, then it
is time to replace the lamp with a new lamp.
