Question about Hitachi 42V710 42" Rear Projection HDTV
Your problem is a bad optical engine. These units run with alot of heat and sometimes it cooks the TFT panels or the panels weren't made correctly and go south sooner than expected.
You will have to replace the optical engine or have a technician do it. I have a tip at http://www.fixya.com/support/r4251975-replace_dlp_light_engine which explains in detail how to remove the old engine and install a new unit as well as where to get it at the best price.
Thanks for using FixYa and for the generous rating.
