Question about Hitachi CP-X275 Multimedia Projector
Lamp bulb and power LED indicators are both lit (red). I have replaced the bulb, but the result is the same.
Check the bulb is fully seated and connected. otherwise it could be the bulb firing board or connections to the bulb.

In your Menu options there is a subfolder where it either reads lamp or lamp timer.
Scroll down to it and hold down you right or left arrow key on the Projector for a couple of seconds.

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.

There is a small tab on the lamp cover that should press into an "L" shaped slot on the lamp housing. This tab may break off, and not press into slot far enough to make the lamp dectection switch click. When the lamp heats up, the plastics expand and the detection switch opens. The projector quits as if no lamp is installed. The fix is to make an extension for the tab. I cut a small piece of sheet metal and crazy-glued it to what was left of the plasic tab.

Probably overheated. Turn off the power and wait for the machine to cool. Then check that the filters are clean and that nothing is blocking air flow - and that fans are running. Turn it back on. If the same thing happens, they say to replace the lamp. I would check the number of hours on the lamp - it may be nearing end of life. Hopefully, it is a ventilation problem.
