Question about Optoma RD50 50" Rear Projection HDTV-Ready Television
Perhaps one or more of the cooling fans are inoperative. One of the fans is easily accessible by removing the two screws that hold the grille cover on the left side of the set. When you power up this is one of the fans that should kick on. The other fans require removing the back panel and probably will require a service tech for replacement. You can enter the service mode by pressing "Menu"- 619 -"Menu" and going to "INFO" on the menu bar. You can check your system temperature and it may indicate which of the fans is not working.
