There is a menu item which has both the lamp hour reset and check air flow, etc. You must go into the menu and reset the air flow item. MAKE SURE YOU CLEAN THE DUST FILTER!! Heat is the number one killer of projectors and Hitachi's run "hot". I clean my projector once a week--Hey, I'm not rich. lol! Also, excessive heat will cause the lcd panels to fail prematurely and cause lots of other components to do the same.--Rick
if the timer is reset, try cleaning the color wheel. Optoma HD20 Projector Cleaning this video is for an optoma but the color wheel is cleaned the same way in most DLP projectors. Dirty or dusty color wheel sensors cause the projector to shut down and act like its the lamp.
If you do not have a remote here is how to reset the filter time. Use the "Menu" bottun to get the "easy menu" to display. Push the down arrow until you get to "Filter Time," then push and hold the RIGHT arrow to reset the filter time. DO NOT try to reset using the "Reset" option on the easy menu, it will not work.
What you want to do is go to the advanced menu, find the filter time and using the remote hold down reset button for 3 seconds or so while the filter time is selected. This will bring up a reset menu and reset the timer.
easy on botem vent unscrew it then u see screw in ther holding balest of the bulb unscrew it litte pull up action on its arm as u will see lift it all out to get new in then reset timer ok
First find someone you know who has a working unit, just to make sure you don't have a problem with your PC output or the cable so you KNOW you have signal at the input.
If no signal then, make sure your input is "configured" correctly in the user menu.
I would have to think your VGA input board on the projector is faulty but let me know what you find.
