Secure the lamp cover and the air filter cover of the
projector body if the projector does not power on. Ensure that the power
cable is firmly connected to the projector and an active power plug. If
the projector was turned off and then on quickly--let it sit for 90
seconds before trying to turn it on.
Replace the projection lamp if the projector will not power
on or if the lamp indicator is flashing. Turn off the projector and let
it sit for at least 30 minutes. Locate the lamp cover and remove or
loosen the lamp cover with a screwdriver. Carefully remove the
projection lamp from the projector housing using the handle, if
Place the new projection lamp into the projector housing and
secure it to the projector. Replace the lamp cover and reset the lamp
timer. Power on the projector to ensure the new lamp is working
Remove the projector from the enclosed area to allow air
circulation if it constantly overheats. Place the projector into an open
area and make sure there is no blockage for the ventilation holes.
Unplug the projector for at least 45 minutes to allow it to soft reset.
Clean the air filter to allow the projector better air
circulation. Turn off the projector and unplug it from the outlet.
Remove the air filter cover and use a vacuum to remove dust from the
area. If the filter is unable to be cleaned correctly or is damaged,
then replace it. Pull the air filter from the projector and place the
new one in the now empty slot. Close and secure the air filter cover.
Here is some information on this model which I hope will help...
The lamp indicator lights when the lamp is due to be replaced. It will flash if a circuit abnormality is found. The temp indicator lights if an abnormal temperature is detected. If it goes too high it will shut down flash.
The lamp indicator is furthest away from the power switch if that helps.
If the lamp timer was approaching the end of the lamp life you would see a REPLACE LAMP nag screen when the projector is turned on. The fact that you have not mentioned this suggests that this is unlikely to be the problem.
The filters on the model are on the underside. There is a removable panel directly under the lens. You should not use canned air as you are blowing dust into the projector. It is recommended that you use a vacuum cleaner. Filters should be cleaned every 100 hours and replaced when the projector is relamped. You can wash the filter by hand with water only, ensuring it is dry before replacing it. Do not run the projector without the filter in place.
Replacement of the lamp can be done as follows:
1. remove the power and keep the projector under a soft cloth.
2.There is small door with one philips head screw which will open the cover.
3. You will find the lamp with two screws which are marked . remove the two philips head screws and using the handle which can be taken out from a catch , pull slowly up. do not pull violently.
4. Clean before you put the new lamp into the slot, replace with the two screws after the lamp goes into the connector.
5. clean tthe filter after you remove the cover and set it back.
6. Switch on and use the menu to reset the lamp timer.
You are now ready to use the projector but take care to keep in ventillation and clean the filters occasionaly.
Helpful I hope. Good day
1:Remove the lamp from the projector. Ensure that it has no cracks, discoloration or "smoky" appearance.
2:Try removing and reseating the lamp, or to try another lamp.
3:Reset your lamp timer. Most projectors have no way of knowing if you physically have replaced your lamp or moved it out . They rely on the user resetting the lamp timer
4:Pull the lamp back out of the unit, give is a brisk shake and reseat the lamp. Occasionally there is some buildup on the lamp contacts or filament during manufacturing.
5:Are the input and output vents blocked or obstructed in any way? That could cause overheating problem and what you see with your projector is one of it's symptoms .
6:Are the filters dirty or clogged? Most manufacturers will recommend filter cleaning on a monthly basis depending on usage .After cleaning the filter always remember to reset your projector .
7:Remove any extension cords, power strips and/or surge suppressors. Many current model projectors will not even try to ignite the lamp if they detect drops or fluctuation in voltage supplied to the unit. This is a safety feature to reduce stress on the lamp.
OK, let me throw out some possibilities. Most projectors how a built in lamp and filter timer. This lets you know when you need to clean your filter or replace your bulb. If left unchecked some models can prevent you from using the projector til the maintenance has been resolved. Clean your filter and refer to your owner's manual for how to reset the timers. If you still get the blinking or red lights after you have reset the timers then you may have a bad bulb or the contacts in the lamp assembly are tarnished or corroded. Pull out the lamp assembly and make sure the leads to the lamp are tight now take a small knife and scratch the metal contacts that the lamp assembly uses to connect to the projector. Clean them well so they will make good contact. Reinsert the assembly, close the case, and try it out. If you do not know how to take out the lamp then refer to your manual as it will have detailed instructions. If your projector still does not work then your lamp is bad and needs to be replaced.
this is a fairly old model!
the lcd optic engine requires cleaning as the mirrors inside will be dusty,also from what u have mentioned,it appears that the polarising filters inside are damged.pl check if the image that u see is spotless.if it has permamnent patches of green or red or yellow, then the polarising filters are damged & u need to change them!
