There should be a filter next to the fan, you can take it out and clean off all the dust. this will help it cool better. also, make sure wherever you use it, it has clear space round it and away from raditors etc

Red lamp or heat light is flashing while projector is off. Can't be sure which it is because it is mounted 16' up. I've cleaned projector & filter with canned air from 12' ladder and red light stops...


Hi,
Here is some information on this model which I hope will help...
The lamp indicator lights when the lamp is due to be replaced. It will flash if a circuit abnormality is found.
The temp indicator lights if an abnormal temperature is detected. If it goes too high it will shut down flash.
The lamp indicator is furthest away from the power switch if that helps.
If the lamp timer was approaching the end of the lamp life you would see a REPLACE LAMP nag screen when the projector is turned on. The fact that you have not mentioned this suggests that this is unlikely to be the problem.
The filters on the model are on the underside. There is a removable panel directly under the lens. You should not use canned air as you are blowing dust into the projector. It is recommended that you use a vacuum cleaner. Filters should be cleaned every 100 hours and replaced when the projector is relamped. You can wash the filter by hand with water only, ensuring it is dry before replacing it. Do not run the projector without the filter in place.

Projector shuts off after 45min


if the fans continue to run after the lamp shuts off, there may be an overheating issue. blow the dust out it with canned air. the dust keeps in the heat that the projector is trying to expell. also keep things away from the vents. if the fans and the lamp shut off at the same time, you have a power supply issue, usually dried caps due to heat. if it is the power supply, you can send it in for repair or buy the part and do it yourself. either way, try av solutions in ny. they're really good. www.avsolutionsny.com

Cinego is randomly shutting down


if it is overheating, blow out the projector with canned air. excessive dust keeps in the heat that the projector is trying to expell. also, make sure all of the fans are working properly. if it's cleaned out and the fans are running, you may have a main board issue.

My benq projector keeps blowing lamps.


first, blow out any dust with canned air. dust keeps in the heat that the projector is trying to expell. next, don't buy cheap lamps from random websites. you get what you pay for. and make sure you have the correct lamp that the manufacturer states. also make sure there is sufficient space around the projector. the vents cannot be blocked. lastly, reset the settings to factory default. many times there is a low power/full power setting. the fans go on full on high power. there should be at least 2 fans. one for the lamp, one for the optical engine. may be one for the power supply. if the one near the lamp is not blowing much, replace it.

TOSHIBA SATELLITE LAPTOP a300d-14O TURNS ITSELF ON AGAIN AFTER SHUT DOWN WHEN LID IS CLOSED


Your power management in Windows is corrupted. I would do a system restore to an earlier date.
1.
Click Start, point to All Programs, point to Accessories, point to System Tools, and then click System Restore.
2.
On the Welcome screen, click Restore my computer to an earlier time, and then click Next.
3.
On the Select a Restore Point page, select the date from the calendar that shows the point you'd like to restore to, as shown in Figure 2, and then click Next.

Figure 2
4.
On the Confirm Restore Point Selection page, verify that the correct restore point is chosen, and then close any open programs.
5.
Click Next if you are ready to proceed or click Back to change the restore point.
6.
The computer will shut down automatically and reboot. On reboot, you'll see the Restoration Complete page, and then click OK.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Canon LV-S1 New bulb but won't power up


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.

Projector shuts down after only a few minutes.


I'm having the same problem. My Model is PB8253. Projector started, then afer a couple minutes it goes off with the red lamp led flashing.
Just replaced the lamp, but the problem persists. Tried to remove all connecting cables, except for the power, but still the same problem.
