Sounds a lot like a heat problem; the unit may not be running hot but there may be a bimetal thermal switch that has become fussy.
If you have an electronics supply nearby, they will have 'freeze spray' and if you procure it, you can see if the projector will turn back on if you give it a shot in a vent. Do NOT spray it on a hot lamp; it may cause it to fracture.  

I would also keep it out of the reach of kids since it can impart a nasty 'burn' if misused.
If this does make it turn back on, you will have to come back and seek help in locating the failing switch although the common ones are disc-shaped with two contacts coming from them.
This construction is failing in 100s of thousands of drip coffee makers too.

My Sanyo plc su20n comes on but shutts off after a couple of minutes. Does not give a temp warning just ready indicator goes of and picture goes off. IF you wait a couple of minutes the ready light will...


check the physical nature of the lamp in the projector. around the filament of the lamp, you might notice dark corrosion building around it. this what normally cause premature shut off.

Lamp didn't strike


Hi,

lamps are affected by strikes. each strike erodes a part of the anode. so in essence, the lamp wears out. However a Xenon has a much longer hour life as once it is running, it cares "relatively" little about how long. SO for commercial units, this is an advantage. there are also larger potential issues about colour stability over life.

with UHP, they care only minimally about strikes, it really is not even a strike, so while frequent on and off can kill it early, with normal usage, you are going to be fine. However with a UHP, if a lamp runs for longer times... then you have issues. THe way i had it explained to me was as such;
With a UHP, it gets up to proper operating temp in about 5 mins. once it is there... it SLOOWWWLLLLLYYYYY continues to heat up. After about 2-3 hours, it starts going outside the nominal operating range. once it does so, it starts to degrade the lamp. thereby lowering life expectancy. if you shut it off after about two hours or so and let it cool for ten mins then do it again for two hours... you are in a much better place. In a grand scheme, apparently if you run the proj for an average of 4-6 hours every time, then expected lamp life goes to about 50%. THis is very rough and in a general sense so just take it as general guidelines.

TIPS TO EXTEND PROJECTOR LAMP LIFE:

Lamp life for a projector will vary based on many factors including application, installation, intake of cool air and exhaust of hot air, usage, and proper maintenance. Heat buildup can reduce lamp life and even damage your projector. Here are some tips to help your projector lamps last longer.


Once you turn on your projector, wait at least five minutes before turning it off to allow the fan to properly cool the unit. After the fan has cooled your projector, you may unplug it and store it as desired.

Do not obstruct the air intake or exhaust vent. Paper should not be placed on top of a projector, or where vents are located.
.
Keep the exhaust vent at least two feet from any object.


If the projector is built into a compartment, wall, ceiling or shelf mount, the minimum distance requirement (usually at least two feet) stated in your owners manual must be maintained.

Clean the projector's air intake filter every three to six months -- or more frequently -- based on your operating environment.

Do not move your projector until the lamp has cooled (about five minutes).

Run your projector for two weeks and/or 20 hours shortly after your purchase. If the lamp is going to fail, it will usually occur within the first ten hours of operation. Lamp warranties typically last just 90-180 days from the date of purchase, rather than the first installation.

When you purchase a replacement lamp for your projector, remove the existing lamp and use the old lamp as your spare. If your projector is new, test the original lamp for the two weeks/20 hours before removing and storing as a spare.

I hope the info. which i have given you solves ur problem if not i am sad to say you have to get it repaired..

Goodluck,

Projector would turn on then turn itself off


Ok I have not seen the projector so hopefully you will reflect that in your ratings. It could be the lamps ballast that is your issue or the lamp counter reset might have gone bad on you. Most dells the ballast would be the problem area. The ballast is what the lamp connect to. That is what powers the lamp. Ok when those go bad you will see wierd visual effects not created by the projector but the problem alone. Now do not shoot the messanger here but 9 times out of ten that is what the issue is. Soince this solution was free at no cost to you I would at least expect it to be rated. First thing I would do here is check the lamp again, check the lamp door, and ultimatly check the ballast.

Good luck to you please rember to leave a rating and feedback,

Replaced bulb but unit goes through cool down then shutts off


You can't, since the unit doesn't have the ability to do what the remote can do. However, the remotes are inexpensive and easy to obtain. Simply type in "Cinego Remote" as a search expression on your search engine, and several places will pop up. Alternatively, contact your local Radio Shack store.

I turn on the 4805,green led blinks & bulb does not come on?


After a few minuets does the green blinking light turn to a red blinking light?

If so the problem is the lamp did not strike.Either the lamp has failed (most likely) or there is a problem with the power supply (less likely)

Lamp


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

Lamp light


That light is there to tell you that the lamp is close to the end of its useful life. It simple monitors the amount of current that the lamp is drawing, so if the lamp stops drawing a preset amount of current, the lamp light will come on, indicating to you to order a new lamp so you have one when this lamp finaly burns out. Good Luck
