There is a side panel where the Lamp is located and held on by a screw or two.
Open that compartment and vacuum out all dust. Also any fans should also be cleaned.

Why does my projector keep switching itself off?

This sounds like an overheating issue, with the temperature sensor shutting it off when it gets too hot for safety reasons. Assuming this did not start until after you replaced the lamp, my initial guess would be that either the wrong lamp was used, and it's generating more heat than the unit feels comfortable with, or, the temperature sensor itself is going bad.

I have a Panasonic pt-56dlx75 television that has

follow this recomendation.God bless you
Temperature is a common reason why many Rear-projection TVs do not perform well when they get to hot. You may start to see your TV shutting down automatically when it overheats. Here are a couple of things you can do to prevent overheating. First make certain any TV ventilation ports are free and clear of debris and dust. Second make sure the TV has enough room for airflow. Third, the temperature in the room should be around 72 degrees. Due to the high degree of heat generated by a rear-projection TVs, it is not advisable to watch TV on a hot days when you don't run the air condition. This could cause damage to your TV.
  • Check the fan. Once the television is turned off, it is just normal for its fan to become louder. A projection TV actually depends on its lamp, which requires cooling so that it will not prematurely burn out. If the room where your TV is placed is very hot, the fan would also continue to run.
Replace projection lamp. To properly do this, make sure that the lamp's bulb has cooled down and the TV is unplugged. Carefully remove the cover of the lamp's compartment using your screwdriver (Phillips-head). Unscrew the sealed part of the lamp that can be found at the television's rear part. Take away the old lamp cartridge and then insert a new one. Seal the lamp with screws, replace its cover and then screw tightly.
iF THE Problem persist you have to fix it the power supply inside.
God bless you

Message says airfow blocked, turns on for about a minute then shuts off

1. Remove the air intake filters on your DLP projector. As explained by InFocus, a manufacturer of LCD and DLP projectors, each DLP model will house the air filters in a different location. However, for most DLP projector products, the filters are accessible by unclipping a simple plastic latch.

2. Wipe the air filters with a small cloth dipped in rubbing alcohol.

3. Blow compressed air into the unit's vents. This will force some internal dust out of the DLP projector, but you may still need to open up the unit for additional dust removal.

4. Unsnap the main cover from your DLP projector. Because DLP projectors need periodic lamp replacement, the main cover is rarely secured with screws or bolts. However, if the DLP projector's cover does not snap off, then you'll want to inspect the unit for possible screws or an alternate release latch.

5. Reach in and remove visible dust globs with a paper towel. Be careful to avoid touching the lens, as fingerprint smudges can diminish DLP projector image quality. If you accidentally smudge the lens while picking out dust blobs, wipe the lens with a dry, lint-free microfiber cloth.

6. Spray compressed air into your DLP projector to remove any lingering dust particles.

7. Close up the projector and reattach the filters.

When tv is turned on message comes up that tv will shut off....check for dust etc. Room is cool. Tried system reset. removed and reset bulb in place. Any ideas? Barry

Cool room will not have much effect on the inside temperature of the TV. Check for the dust on the air filters of the projector & clean them. Inside the projection TV there is thermal sensor which senses the temperature. If it is more than the maximum recommended temperature set by the manufacturer, it shows the above message. It is quite likely that your TV's thermal sensor is not functioning or a fault has occurred in the sensing circuit.

It seems as though my Sony HD tv's picture has gotten darker over the few weeks. Does the bulb need to be repalced?

IF it is over two years since it was replaced, this is the way that they fail---get darker just before they fail completely.

Average life span is 2,000 hours which works out to for most people about 2 years.

Google the model number with the word Lamp after it and you will find dozens of places to purchase a replacement---the lamp is meant to be a customer replaceable part.

If this told you something you did not know, rate this solution as very helpful as I do this here for free.

I have a infocus X2 projector that powers on for about 15 seconds then turns off ( the light goes from green to red). What is the cause of that.

Your projector most likely has a bad ballast board(lamp power supply) that is the most common cause of this problem. The reason why this happens is because the lamp is drawing more power than usual and hence the protection circuitry will shut down the projector as precautionary measure to avoid damage to the components.

Hope this helps,

My infocus IN1 projector won't turn on anymore.

It may be the lamp is out. Normally a projector will try & fire the lamp 3-5 times then shut down with a different color light like amber or red. If the lamp doesn't light then it could be the lamp or perhaps the lamp ballast that starts the lamp has failed. A stuck fan also causes similar symptoms. There's 2-4 fans in the projector if one is stuck or bad it will turn off within 5 seconds or so after the lamp lights.
Does your lamp light at all? Are the lights a different color after it shuts down? Answers to these questions help figure out what's wrong though it's impossible to say for sure without looking at it. I service almost all Infocus projectors if you would like a quote please reply with your email address or write me at
Good Luck,
