Hi there, I have a Sharp pgd3750 and I’m having a problem with it. Ive just replaced the lamp and not the projector won’t turn on. When I press the power button the lamp light indicator blinks green and the power light is solid green. After a few seconds, the fans shut off and the power light then blinks red. Ive tried resetting the lamp hours by holding enter, down, menu, and power to no avail and I’ve checked the lamp cover switch and it seems to be in good order. Please guide me down the right path! Thanks
