Lamp is bad, probably very high hours or just defective. Replace asap or you can damage your projector.

How do I open up a Rank Aldis 2000 Slide Projector to replace a bulb and free a jammed slide?


1. Prepare to turn projector upside down.
2. Unscrew & remove focusing lens.
3. Turn projector upside down & look from the base face of the projector towards the lens aperture - for a slot just under the lid lip. There is a black tab which can be slid with a screwdriver away from the slide path.
4. There's a similar slot at the back under the lid lip and the end of the row of vent holes.
5. After sliding these, the lid is loose - so while holding the lid in place, turn the projector back over onto its feet.
6. The lid now simply lifts off - first at the slides side, hinging away and then off.

A student tripped and unplugged the projector. Now


The projectors usually keep a fan running for a cool down time after the switch is turned off. It's possible that there is that there is a burn mark on the bulb or other part due the sudden power drop. At least have good look at the bulb and immediate area to see if there is any sign of visible damage.

I have sanyo projector model PDG-DSU20E. Few white spots appeared on the right side of the screen. Gradually the spots has filled the right side about 1 feet is width till bottom of the screen. Now few...


1,white spots appeared on screen,means the DMD is broken,you need a new DMD.
2,the projector running off after only a few minutes,means the Inductor (Sensing element),near the Color Wheel. Use a cotton swab moistened with alcohol to wipe the Inductor.

Have a good day!

Blower comes on but the bulb won't come on.


Hello, Appears that the bulb is burned out, This is normal for these projectors due to high heat that the bulb produces. These bulb assemblies are very expensive.
Best Regards, Russell

My son just purchased a Bell & Howell 2575C 16mm projector which seems in good working order; however, we cannot figure out how to turn on the light (the bulb appears to be fine)...we've threaded film,...


Chances are that if everything else seems fine and is coming on then most likely you have a bad bulb or it could be loose,make sure its fitted into the bulb holder assy good and snug,dont force it or you will break it at the base.Go to google and google your model number for the bell and howell projector and find out whats available and pricing.A middle of the road or average bulb should be suffice for what your doing.

Everything seems normal but the lamp will not


check lamp door and filters (if you have them). if they are not closed or in all the way, the lamp will not go on. otherwise, the ballast may be bad and needs replacing.

Hy, having problem with to conect projektor to the computer Anybody can help


The projector should have a cable similar to the monitor cable that would normally be hooked into the computer. The cables work the same and the one coming from the projector will use the same port as the normal monitor cable. Make sure that there is a good connection on both ends -sometimes one or the other get moved and the connection is lost.

Once the cables are hooked up, the projector should be turned on. Normally the projector will soon begin a startup routine and will cause an image to be shown on the screen. You can focus the image during that time.

After the image goes away you should be able to display whatever you want from your computer's software.

Normal problems in doing this are: leaving the lens cap on the projector, having a burned out bulb - once the power is turned on for the projector, it should cause the bulb to come on. Some models have a power on switch and a display on switch that must both be pushed to make the bulb light up.

Hope this helps.

LP690 projector displaying strange lines


to adjust those mirrors, you need to power down, unplug, remove the top, remove the wires from the main board, remove the main board, adjust one mirror, reinstall everything, power up, see whatever difference it made, power down and repeat until it's fixed. it's quite a chore. if that's not the problem, you'll need to replace the optical engine (which isn't cheap) because they don't sell individual parts.
