Re: Projector smells hot

I have a Dell 2400mp 3,000 lumens. After you pull out the old lamp, find an air chuck, now be carfull, you want to make sure that there is no watter in the air line, trust me what can go wrong dose.<---. Now make shure that the air pressure going into the projector fan is not to much, for example 120psi would rip your projector appart.This was the best cure for mine, be carfull with those air cans also, they work well for alot of stuff, but projector fans are a little harder to get to. If you use an air can make shure to hold it in the position it would be if it were on a counter or sitting some other place. And do not put the screws on very tight.

Lamp didn't strike


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.


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..

I have a Sony VPL-CX61 Multimedia Projector. I just changed the lamp and I cannot get the "please replace lamp" message to go off.

When you use a projector it automatically keeps a timer of how long the lamp has been used for. The message that comes up on screen saying "please replace the lamp" comes up not because it's some how sensing that the lamp is getting old, but because the lamp hours gets to a certain number (usually up around 1500 hours). Because of this when you replace the lamp you need to reset the lamp hours counter, or the projector doesn't even know you've changed it. Every projector does it this way, and they all do it a different way, I googled the model you gave us and found this set of instructions on how to do it, so give it a go.

Reset the lamp counter hours of operation for the projector SONY VPL-CX61
Using the remote commander while the unit is powered up, press "ENTER", "ENTER", "LEFT"
and "ENTER" in sequence. A prompt will appear on the screen asking if you wish to enter the factory mode.
Press the "UP" key on the remote and the unit is now in service mode. This sequence will add two new groups
to the customer setup menu. Press the "MENU" button to view.
Whenever the lamp is replaced, the lamp timer should be reset. With the unit in the "factory" mode, press
"RESET", "LEFT", "RIGHT" and "ENTER" on the remote commander. Verify the lamp hours have been reset to
zero in the service menu.

Hope this worked for you,

Last night, a message started appearing saying the lamp needed to be replaced on our Panasonic LCD TV. What is this and is it something we have to do? I think it's the Panasonic PT-AX200 LCD Projector, but...

the lamp is good for about 2000 hours. after this, the lamp may still work, but not as well or for very much longer. after you replace the lamp, you have to reset the lamp timer (in the menu settings).

lamp hours can only be displayed by connecting two test points in side the projector. in normal operation, a message will be displayed on the screen when the lamp hours = 1090. when the lamp reaches 1100 hours, the projector will shut itself off. when you do replace the lamp, be sure to reset the lamp time in the setup menu (this is covered in your manual).
