A tinted image (whether green or another color) is almost always a symptom of a bad or damaged cable - or a loose cable connection. In your case, you'll likely need a new M1 to VGA cable (Part# SP-DVI-A-R).

Assuming that you've made sure that the cable connections are solid at both ends, there is a simple test to verify that this is a cable issue and not a costly projector issue. While the image is tinted green, open the menu. If the menu colors appear fine while the rest of the image is still tinted green it's the cable.

Projector clocked 1000 hours roughly and working fine. However 1 day I tried to turn it own and seems completely dead. no blue light. fuse r al good


Does this projector have an automatic timer that doesn't allow it to turn on after a set number of hours (@ 1000)? If so, you may need to re-set the lamp-hour clock (as if you changed the lamp even though you didn't). Some machines require you to at least slide open the lamp cover to make it think that you changed it.

Can hear sound but cannot see picture


Hi, if your LCD projector turns on and projects light with sound but not the picture on your computer screen, first make sure the projector is plugged into your computer. If it is, check your computer display settings. Go to "Control Panel" and "Settings" or "Windows Setup." Select "Display." Make sure it's set to appear on your laptop screen and the the projector screen. Most laptops have a "Fn" key dedicated to changing the output display setting.


If your projector turns on but emits no light or picture, replace the projector's bulb, often called the lamp. Most have a life of between 2,000 and 6,000 hours. Your projector may warn you when the lamp life is about to expire, although some models simply stop working when the lamp needs replacing.



Thank you.

I replaced the lamp in my Sharp xv-z90u. When I attach the power cord I get a solid green on the power indicator light. I also get a flashing green on the lamp indicator. I tried programming the reset...


First check your bulb properly matched with your projector. After changing the lamp reset the lamp hour (counting from 0hrs). Adjust the osd transparency.

If u set the lamp properly then It may cause the lamp circuit need repair.

Have you got yellow lamp indication before change the lamp? If occur then you have been late to change it. If you used it up to 2500hrs. then this problem may arise. Check those first if everything ok then may be the circuit have some problem, go to the nearest sharp authorize service center or visit website.

Problems with Projector Panasonic PT-L501XU after change the lamp


was this bought new or second hand?
There is a "Lamp Time" setting that can be accessd using your remote control, check this setting.
Look on page 40 and after that of your manual about ambient temperature bulb failure.

By powering off or hittign the reset button the bulb should stay on IF the projector is gettign a signal from a device to show an image. If the projector is not hooked up to a device, laptop, TV, etc. the bulb may turn off to save hours of operation.

The optoma hd72 projector lamp goes out after 30 seconds.. the big game is this weekend... what can I do?


I had this exact same problem. I have changed bulbs gotten 1000 or so hours from new bulb, changed the lamp driver and gotten about 600 more hours from new lamp driver. New lamp cost me $350, lamp driver cost me $120. Then I read on a page to try and flip it right side up, because I had it ceiling mounted upside down. I flipped it right side up and it works perfectly and has been working perfectly for 2 months now. I know it sounds stupid, but it actually worked for me, and it costs you nothing to try it. For some reason, gravity effects this unit.

HD72I WORKS FOR 30SECONDS AND THEN SWITCHES OFF


I had the same problem with very few hours on the lamp. Sent it back to the factory and they said the fan was overheating causing the bulb to shut down. They replaced the fan and the bulb for free under warranty. I noticed before I sent it the projector was putting out an incredible amount of heat. MUCH better after fan replacement.
