Above are your manuals for use and repair.

Sometimes there is a resettable thermal fuse near the lamp, this may have to be reset before it will go again. Sometimes there is a "Counter" to be reset too, but not always.

There is no image or light coming from my projector


Hi Sane,

Multimedia Projectors uses a high power lamp to project the image onto a screen. These lamps have a typical life of 2000-3000 hours. It is quite possible that it may have blown.

  1. Confirm that the unit itself switches on. You should have some sort of visual feedback from the projector that the unit is switched on, ie. the power light comes on, if it doesn't, check your power chord.
  2. If there is power on the unit, but no image/light, check the unit for a fault indicator/light. Cross reference this with your user manual.
  3. If you are unable to verify or do not have a user manual, "google search" your make, model and fault-code, else
  4. approach a sales consultant at your nearest Audio & Visual retailer for advise.
My take is that the lamp has blown and needs replacement. These can be obtained from a Audio & Visual Retailer and can be self-installed with a little technical knowledge.

Dell 1209S Projector, tries to turn on, and the fan comes on for 30 seconds and then goes off again. It tries this several times and then the light bulb icon comes off and it doesn't do antything else


Lamp is burned out or makes a popping sound.
When the lamp reaches its end of life, it may burn out and may make a loud popping sound.
If this occurs, the projector does not turn back on. To replace the lamp, see on page 38.
LAMP light is solid amber If the LAMP light is solid amber, replace the lamp.
LAMP light is blinking amber If the LAMP light and the Power light are blinking amber, the lamp driver has failed and the projector will automatically shut down.
If the LAMP light is blinking amber and Power light is solid blue, the color wheel has
failed and the projector will automatically shut down.
Unplug the power cord after 3minutes then turn the display on again. If this problem
persists, contact Dell™.
TEMP light is solid amber The projector has overheated. The display automatically shuts down. Turn the display on again after the projector cools down. If the problem persists, contact Dell™.

My projector's power light is red, but when I click power it won't turn to green (on)


The likeliest problem here may be a burned out or failed projector bulb. Most projectors will fail to power up at all when if the bulb is out. The HD20 user manual does not specify a red light as an error indication option however, generally amber.
User manual .pdf is located here (takes a bit to download for it's size), Projector Status Indicator instructions are located on page 40.
Here on the product page itself, an email to Optima support may be warranted given the red instead of amber error light.
If you had any messages recently indicating your bulb life was nearing it's end, again, this would be my first guess. Certain models of projectors do have a tendency of blowing through bulbs even before any warning message comes up. I had an experience with a certain brand/model that for the last 3 replacements has given only about 1/4 of the stated bulb life, so unfortunately it does happen.

We use NEC MT1065 and just replace its lamp but it still won't switched on (lamp indicator led is red). How can I reset it ?


Hello, unfortunately the NEC MT1060 - MT1070 series projectors have EEPROM chips built into the lamp housing which counts the hours that the lamp has been used for so the only way to reset the hours is to change the lamp for a new one, if your old lamp has only had the reflector replaced then it will make no differance because the chip tells the projector weather or not to power up depending on the hours its counted, i have not yet found a way to reset the chips even by reprogramming them, i'm afraid the only solution is to replace the lamp with an official NEC unit, but this was obviously their intention, just as an added note, a solid red lamp indicator light means that the lamp has expired, if its flashing red this means its nearing the end of its life, if the status indicator light is flashing then there could be another issue, by counting the flashes you can reffer to the manual in the troubleshooting section to diagnose the fault, I know this is very late, but anyone else reading this may find it helpfull.

TURN PROJECTOR ON. FAN TURNS ON NO LAMP, RED SATUS LIGHT COMES ON


Bulb timer has expired. Press the left arrow, right arrow and power switch simultaneously for a few seconds. The projector should power up, but this indicates that a new bulb is required and should be fitted as soon as possible, as there is a risk of the old bulb exploding.

Plug in the power cord, switch on the projector, and
reset lamp time by pressing the (left and right arrow) and POWER buttons on the control panel simultaneously.
Important:
• If the 3 buttons was not pressed at the same time,
the lamp time may not be reset.
• Please confirm the TEMP indicator illuminates
about 2 seconds and the lamp time has been
reset.
• The projector will not turn on if you do not secure
the lamp lid.
• You must reset the operation time meter after you
replace the lamp.
• Do not reset the operation time meter unless the
lamp has been replaced.

A couple of things...

If the fan is not working, the lamp will not fire. If you have the owner's manual, it should indicate what the flashing lights mean. Check to make sure that the panels are seated properly. When you replaced the lamp, the outer cover was removed. If that is not seated back 100%, the unit will not work. There are a number of safety "checks" built into the unit to prevent damage and possibly fire as the lamps get really hot.

Check the items above and let us know your progress.

red light indicates lamp is expired. even though you get temporary light, the lamp is shot. Try BULBMAN.COM for a new lamp.
