Unfortantly it sounds like you have dirt or dust inside this unit or there is a defective LCD panel. Good Luck

unplug projector for about an hour, and then remove bulb, and filter, inspect areas for damage, also inspect it to make sure your inserting it correctly. put filter and bulb back in, put covers back on, then plug it back in. reset the timer. if you still have problems let me know.

Filter timer needs to be reset

In the advanced menu go to option, then highlight filter time and hold down on the right side of the menu button until the filter time reset menu comes up. When that comes up choose reset by pressing the up arrow on the menu button.

Large dot in the middle of the projected display

there is a burned-in spot on the polerizer light filter for the blue lcd. it makes sure the light is blue coming through, that's why it is black on a blue screen, and yellow when the red and green are the only light showing through. it needs to be replaced. pat # PFiLW0213CEZZ.

Problem with hitachi cp-RS55 multimedia projector sir

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

Hi there

This is a faulty LCD - only way to get of the problem is to replace the faulty LCD.

Must warn you that the LCD's are normally expensive.
