Projector image switches off when image gets super bright

When a full screen of brightness a flash or explosion is projected as intended in the program being viewed, the projector seems to be either exceeding some kind of output limitation or is picking up a signal via it's remote control sensor, causing it interupt the program image, sometimes going to the blue/no signal screen for a few seconds. it will resume play but if bright images, flashes or explosions are still happening in the program it will flip out again for another few seconds... this is really annoying when the most exciting moments of the program usually involve brightness, flashes and explosions. I blocked the window where the remote is supposed to be sensed but i can still use the remote through the air vents i suspect and the problem still persists. I'd just like to know what is going on here, even if it can't be fixed... thanks

I have a Kodak Ektagraphic with no model listed on it at all. How can I find a replacement bulb, all I can find look wrong.


Supplied with 82V, 300W EXR lamp Projection Lamps Quartz-halogen 82 V projection lamps- Here is service manual link http://resources.kodak.com/support/pdf/en/manuals/slideProj/manual/ektagraphic_sm.pdf Several different Models all say EXR 300W As CORRECT Bulb : EXR, 300 W (35-hour lamp life at full lamp/medium-brightness) Sampling of other lamps: EXY (200 hours/less brightness) EXW (15 hours/maximum brightness) FHS (70 hours/medium brightness) Use combinations of lamp brightness, plus half- and full-lamp settings to approximate image brightness in multi-projector presentations. Lamp Tips • Projector operation on line voltages above 125 volts greatly reduces the lamp life. • Unplug the projector before changing the lamp. • Allow for unrestricted flow of air to the exhaust vent to prolong lamp life. • Gently wipe off any fingerprints with a soft cloth moistened with rubbing alcohol.

Can I project outdoors with an Acer PD113 ? and How big will the image be?


Not sure of the lumens or brightness of this model but in the dark it should be bright enough. Most projectors will do up to a 300" diagonal image.

Gradient brightness


Make sure all your cords are plugged in. Try restarting the projector, make sure nothing is blocking the lenses. If the does not help, Call Radio Shack or Staples.

Screen adjustment


Adjust the screen area of the computer’s display settings to match the projector’s native resolution. Refer to your projector documentation for the optimum or native-resolution setting for your projector model. If you can't find this information or are uncertain, most projectors support a maximum of 800 x 600 pixels.
• With certain laptops, you might need to disable the laptop display to obtain the best image, especially when the native resolution of the laptop exceeds the native resolution of the projector.
• Font smoothing will automatically generate a cleaner font outline, both on your laptop and on the projector. To apply font smoothing, do the following:
1.
In Control Panel, open Display.
2.
On the Appearance tab, click the Effects button.
3.
In the Effects dialog box, select the Use the following method to smooth edges of screen fonts check box, and then select Standard or ClearType in the list.


If the projected image is dimmer than it was on the laptop, check your projector documentation for information regarding lamp timers. If the lamp life has expired, replace the lamp for maximum brightness.
If the projected image is not rectangular, try one or both of the following:
• Make sure that the projector is perpendicular to the viewing screen.
• Raise or lower the projector.
If the projected image displays vertical lines, "bleeding," or spots, try one or more of the following:
• Adjust the brightness of the image.
• Check the projector lens to see whether it needs cleaning.
• Adjust the sync and tracking on the projector.

Acer projector


A DMD has no inherent colour capability - it's just a configurable mirror array. If you want to do full-colour projection, then, you'd expect that you'd have to use three DMDs and three coloured filters - red, green and blue.
But if a single DMD's switched in synchrony with a rotating "colour wheel" - a spinning tri-colour filter that lets through red, green and blue light in turn - then the very rapid switching speed of the DMD lets it lay down red, green and blue images in such fast succession that the result is a perfect colour image.
You can do the same trick with a single LCD panel, but it's not a good idea; LCDs are transmissive, rather than reflective, devices, and block something like half of the light that tries to get through them. To maximise brightness in LCD projectors, a three-panel design works better. If you try to pump the entire output of a super-bright lamp through one LCD, keeping it cool becomes rather challenging.
The extreme smallness of the moving parts on a DMD mean that it behaves like a solid state device, not a mechanical one. For all their complexity, DMDs have very high Mean Time Between Failures (MTBF), and well-made projectors based on DMDs can be expected to last easily as long as LCD units, and probably longer. If a DLP projector fails, it's not at all likely to be because there's something wrong with the DMD.

No Video Display


The lamp should be blindingly bright. The light passes through a color LCD and through a series of lenses that will project the image onto a screen. If the light is "very weak", you won't have enough light to project onto the screen. Try using it in a pitch black room really close to the screen. If you can see ANY image being projected, then the unit is fine and all you'll need is the lamp.... usually a rather expensive item.

Bright yellow


I can't imagine a setting that would cause this - It sound more like some sort of fault with the projector's blue LCD panel. (The image is created from a mix of red, green and blue light. If you loose the blue, everything will look yellow.)

Is it capable of showing any shades of blue?

Using any graphics or photo-editing software, create a solid blue image (R=0, G=0, B=255 in your colour settings) and if possible, display this full-screen. Is there any output from the projector at all when you do?

If not, it sounds like it need a professional repair.

Screen goes blank momentarily


cover up the infrared remote sensor on the projector. The heat of these colours or something might be messinf with the infrared remote sensor. TRy this and see what happens. It may just be bad contacts. Some projectors just cant handle stuff like this. Some were meant for presentations and presentations only. BUt seriously try covering the remote sensor to see what happens. If it is an older projector the infrared signal detector might be sensitive to bright light or stuff like that.

TV shuts off with high color images . Example: explosions,bright lights etc


Normally, the screen control being up a little to high, would cause this problem. If no one has worked on this unit when it started may be a sign of something else, for example, the 200 volt line may be running a little low. Check the brightness and contrast for starters and if that doesn't help, then, the screen control would be my next step. Hope this helps.

Why is my projection dark and muddy compared to the brightness on my computer screen?


John here, customer advocate at Dell headquarters. If you can nvigate to the On Screen Display Menu, you should see an "all images" section on the main menu. There you will find brightness, contrast, color temp, white intensity, and gamma controls. You should be able to make adjustments from that menu to sharpen and brighten the image.
