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.
I'd recommend checking the fans of the projector, and make sure that they're spinning. Since you've mentioned that the lamp blew inside the unit, bits and pieces of the lamp might have lodged itself within the fans. It might also have to do w/ the after-market replacement bulb, which I normally wouldn't recommend.
If the LAMP INDICATOR flashing red then.
Problem: Lamp circuit failure
Sulution: your two lamps are ok you need to repair the lamp drive circuit this is repairable and if you don't want to repair you buy a new one lamp circuit and install it.
Did you replaced lamp in projector? if yes, please make sure lamp cover is fixed properly on its position. There is safety switch under lamp cover that needs to be pressed to turn off lamp cover light flash. Thanks.
I have the same problem as posted too, ordered 3 new lamps and they all still do the same thing. I`m starting to think its the projector that has a problem. Anyone got a solution other then keep buying new lamps and try getting it to work... I mean, after 3, how bad lucky can you be that they are all bad lamps...
I sent mine in. They changed the bulb and cleaned the unit. The one thing they did suggest that seemed helpful was to upgrade the firmware. They did this as part of the service. That may be your problem, but I don't know that the firmware is upgradable. Yes indeed, they do charge an outrageous price!! I went through Sharp because they would guarantee the work, and I didn't want to buy two bulbs.
the cover switch is probably not fully made.
Ensure that the cover tangs are pushing the pin
on the miniswitches.
Try putting slight pressure on the fan or lamp cover to see if the lamp/cover light
you will need to do a restart on the PJ to check this out
