Hi Greg147

The resetting is not done in the menu.

Plug in your power cable - Machine is now in standby mode.

Then Hold down the left and right arrow keys on the Projector and press the power button. You'll see a indicator light on top of the Projector flashing twice - Lamp hours is now reset.

Hope this is of help.

SOURCE: Blinking status light

Replacing the lamp with an old one was helpful for me. Good news: the projector itself not faulty. Bad news: I have two projectors with the same issue at the same time (the lamps were replaced also at the same time) after only 400 hours of running.

SOURCE: Reset Lamp Hours Timer

Make sure the main power switch is OFF. Hold the "ON", "MENU", and "VOLUM -" buttons at the same time and turn the main power switch on. Keep them held until the yellow power standby light comes on, then let go. It is done.

I replaced the lamp on my XGC55X Sharp Projector and it worked great for 2 nights (roughly 6 hours). Now it goes to warm up, with the lamp light blinking, and will power down with the status button showing...


Have reset the lamp hours after installing the new lamp? If, not the projector has treated the new lamp as old lamp & refusing to light further. So, reset the lamp hours to zero. To reset the lamp timer do as follows. Plug the power cord into the AC socket of the projector. Switch ON the power of the socket. (not projector) While pressing simultaneously INPUT, ENTER & UNDO on the projector, press ON on the projector. "LAMP 100%" is displayed, indicating that the lamp timer is reset.
If this does not correct your problem then the problem lies in other area. Let me know so that further I can provide you solution. Above things are preliminary

Will not coming on ,standby light is orange temp and lamp light not on


hi,
Just try to reset the lamp hour of your projector. For resetting the projector do the following.

While simultaneously holding down MENU/HELP, ENTER and Down arrow button on the projector, Press STANDBY/ON on the projector.
Remember one thing lamp hour reset is recommended only after the lamp replaced. Before going to buy a new lamp just reset the lamp hour and confirm that the projector doesn't have any other problem.

If these doesn't help then check the lamp of you projector chances for lamp became faulty.
ok

Changing the lamp


There is a small cover plate, about 3"X6", that 'just' snaps off. You might have to use a small screw driver to pry it open. The bulb can then be pulled out. Align the new bulb and press it down into the socket. Be careful not to touch the bulb with your hands; use gloves or a lint free cloth.
