I've changed my lamp (bulb) but the projector starts up, and then shuts down again. I've looked at the manual, and have tried to find the filter. I can only see vents, no filter. Anything else I can do?

HI Clay,Is the green lamp light on fully ie is not flashing.?

There is no reset for overheat, if the problem is like blocked vents when it is rectified the only reset is power on/off and the fatal red or flashing orange error condition should go away

I have seen a simualr model that had the lamp cover open not showing an error but stopping it from working, but I dont think it was the exact same model but worth checking the cover is on properly

How many hours has the lamp done, do you have two of these machines?

If you do please swap lamps between the two again because this sounds like a lamp issue although we should be getting the error code unless the counter has been reset without changing the bulb for new..are you 100% sure your not using 2 dodgy bulbs and thats our issue, because Im suspect on these lamps unless of cause you can swap one into another and see it light, if that is the case then its has to be lamp contacts or a board fault but i need to know more exactly the deal with "known good lamp" and exact lights

Ensure we are fitting the lamp correctly and the contacts for the lamp are clean and fitting tight.Please ensure we have checked the silly things like lens cover, signal is being sent and pc aint asleep etc

It is 2.30 am in Oz, I'm off to bed but let me know some more info if you can and I have a dig deeper at work tommorrow for you and see if i can come up with some solution because all i can see it being now in my sleepy state is bulb, bulb contacts, lamp cover, mis reading lights, silly stuff or a board fault....

Cheers below is your user manual and the error light table

Speak soon

There are 2 possible causes.

The first may be due to overheating. Most projectors have a "air filter" that can be removed and cleaned. If it gets clogged with dust over time, the projector can't breathe and shuts down.

The second cause may be your lamps life hour clock. Most projectors keep track of the amount of time that their bulbs have been active. Once a preset # of hours has passed the projector will limit functionality until a new bulb has been installed AND the lamp life clock reset. Most projectors do not automatically reset the lamp life clock after a new bulb is inserted.

There should be instructions on how to reset the lamp clock in your users manual, and info on cleaning the air filter. Unfortunately I went to the Sanyo website and was unsuccessful in locating a PDF of the user manual for you.

The bulb is not lighting correctly.
Take out the bulb and check the connectors are not dirty and reinsert.
See if you can see the bulb looks ok, you may be unlucky that the bulb has prematurely failed (hope not)
Try again to start it.

firdt off, did you reset the lamp counter? did you clean the dust out of the projector? it may be overheating as well. if the lamp looks ok, you may have just blown the ballast. try projector doctor online.

sounds like you may have the wrong bulb and it is being overpowered.

could b ballast or powercsupply board

You have 1 of 2 possible problems.

(1) You need a new lamp.

(2) You have an overheating problem.

Just a quick couple of notes about your projector. It is a DLP projector (not LCD) and as such the machine as no air filters to clean. It does have air intake and air exhaust grilles, but no air filters to clean. This next part comes directly from the owner' manual for your projector:

When the lamp operation time exceeds 2000 hours*1 *2, the projector automatically shuts off and can’t be used until the lamp is replaced and the lamp operation time is reset.

Your machine is designed to give visual warning messages at 1500 hours used, and 1900 hours used. Did you see any visual warning about lamp life over the past few months?

If you were experiencing an overheating problem, a "TEMPERATURE!!" message would flash up on the screen just before the unit shuts down. If there is no warning, you don't have a heat problem.

If you have a replacement lamp available, install it and reset the lmap hours according to your user manual. If you don't have the manual, google it on the web (it available).

You need to reset the lamp hours. Here is the manual to tell you how to reset.

Good Luck and please Rate. FixYa!

You need to clean the filter , the unit is shutting down so it doesnt over heat..look for online manual on how to remove filter and blow off dust.. Good Luck

Have you cleaned the filters? In this situation, the fan and power shuts down even before the bulb lights up and heats up the unit, but perhaps the unit can detect clogged filters.

You can download the manual here if you don't have one. Instructions for cleaning the filters are on page 37.
