Acer PD100 overheating

My acer PD100 is overheating. It will stay on for about 20 minutes when started from a cold state (less when starting warm). It gives the overheating warning in both standard and eco modes and then shuts down.

I used an electronics vacuum to clean out all the vents and it seemed to stay on longer for a day or two. I've tried a new lamp with same results.

Any ideas? Should I try to replace the cooling fan?

    The fan is running, though it doesn't seem to be varying in speed at all. It is running at a low RPM, so I'm guessing that a fan replacement might do it.

Solved ! I had the same problem. After connection to notebook and after attempting to correct colors. Overheating after two miutes and shut down. Reassembling aned cleaning was not helpfull. All seemd OK. Resetting the factory default was not helpfull too. But, I tried something, what ist restricted. After aprox one or two minutes, no more of projector work, I switched out the power not correctlly according the documentation, but the main cable from the wall outlet. I was little bit angry and this is what why I forgot if I tried this procedure ones or more time. But, that was hepfull, and projector now runs correctly. I supposed, that my experiment made "reset" of something. I would like if that solution wil be helpfull for you. Kamil, Prag.

I found that by resetting the factory defaults the problem goes away. I have experienced this issue a few times after attempting to correct colors.

this projector does not have the best picture or color quality.

I just spoke to a repair agent for Acer projectors about this problem. It was a very common problem with this model (PD100) and Acer never really got to the bottom of it. There is a 50/50 chance that upgrading the firmware will resolve the overheating issue. The rest of the time a replacement mainboard is required to solve it. Unfortunately this firmware is usually only available to Acer channel members. If you do have it you'll need to upload it via a usb dongle of some kind. If anyone manages to locate the latest firmware please let us know where to find it. Thanks.

I have an acer PD100, and i am having the same problem. But what I discovered is that the projector only overheats when you connect a video source to it. It will run for an hour, but as soon as i connect a source, within less then 2min the unit will display the overheating warning and then shutdown. The crazy thing is this is my second PD100 to do this. the first one i had did this after owning it for only about 3 months. Acer replaced it finally after sending it in to be repaired 3 times. Now the new has started doing the same thing about 4 months after i got it. (Has less the 150 hours on it) This really disapoints me in Acer, because I have been using Acer Aspire products for years. If anyone has any idea how to repair please post a comment. It is really disapointing paying $860.00 for a projector that doesn't work.

Hi DaveMcCall

Yes this could either be a fan or a sensor that is faulty and will need replacement.

Both are very cheap and easy to replace.

Try checking first of all if all the fans are working ok.

Acer dlp power shut off after a few minutes on

That's typically caused by the thermal protector. If the fan is running normally and there filter (if there is one) is clean, then the thermal sensor has probably gone bad. It will need to be sent to a repair center.

Acer Aspire One notebook.when turn on,starts to boot goes windows did not start screen,can choose option and windows starts to load then just shuts off.if you do not choose option shuts off after about 20...

This is generally a hardware issue - if the computer is under warranty get it fixed through Acer. If not you may need professional help. You don't mention how old the laptop is but if it is older than a year or two and you live in a dusty environment it could be overheating. If the fan is not running or always running on super-high then it is probably overheating.

Another thing to try is using a boot CD (any boot CD will work) and see if the computer still shuts down after that 30 seconds. If yes, definitely hardware. If not, possible that it's a windows issue.

Hope that helps!

Acer Extensa 4420 overheating

The laptop must be dismantled to access the motherboard, buy a can of compressed air attach straw. Now remove fan and the heatsink, blow out all open ports and fins on the heatsink and fan, next! remove thermal grease from the processor and heatsink with rubbing alcohol and a paper towel, now! apply fresh thermal grease to the processor and heatsink, "small thin layer evenly spread" now assemble, "solves most heat related issues"

Acer Multimedia Projector PD100 DLP overheating problem

blow the dust out of it with canned air, make sure the fans are all spinning. this should remove the causes of overheating. if it still says that it is overheating, replace the thermal sensor (usually near the lamp or the lamp fan).

ACER PD100D Overheating

I found that by using the menu to reset to factory defaults fixed the issue. It appears to be a combination of settings that causes the issue. I have created this situation a few times while trying to get more accurate colors from the projector.
