You have thermal protection issues.

On some projectors, once the thermal protection has been activated once, it will activate again at a lower temperature!!!

Inside your Sanyo there are several temp sensors (they are actually temperature-sensitive resistors, called thermistors). I have seen this many times as an electronic technician working on multimedia projectors. For the techs out there, they are actually NTC thermistors (NTC= negative temperature coefficient, meaning as temp goes up resistance goes down).

Once a thermistor has activated to save your machine form heat damage, it may activate again at a lower temperature. The only solution is to take your projector to an authorized Sanyo warranty repair depot, and have the thermistors replaced in your machine.

Typically, there is a thermistor to monitor lamp temperature, and a thermistor to monitor optical block temperature. Better quality machines may have more thermistors, some machines only have one to monitor the lamp temperature.

Hi Here is the info for you :: Caring For The Air Filter The air filter should be cleaned about every 100 hours. If the indicators or a message prompts you to clean the air filter, clean the air filter as soon as possible. If the soiling will not come off the air filter, or it becomes damaged, then it needs to be replaced. Please replace the air filter as soon as possible. memoWhen you replace the lamp, please replace also the air filter. Turn off the projector, and unplug the power cord. Allow the lamp bulb to cool for at least 45 minutes. Apply a vacuum cleaner to the top of the filter cover and the air filter to clean. If the soiling will not come off the air filter, or it becomes damaged, it needs to be replaced. If the air filter needs to be replaced, contact your dealer to prepare a new air filter. Tell the dealer your air filter type. Turn on the projector power, and reset the filter timer. (1) While the projector running, press the MENU button to open the menu. (2) Choose the ?OPTION? on the menu using the / button, then press the button or ENTER button. (3) Choose the ?FILTER TIME? using the / button, then press and hold theRESET button for 3 seconds. (4) Choose the ?RESET? using the button. memo Incorrectly resetting of the filter timer (resetting without replacement, or neglect of resetting after replacement) will result in incorrect message functions.

SOURCE: Displayed massege to check air flow

With most projectors there is a foam air filter behind a grill that is the opening to the cooling channels. A fan ensures air flow to cool the lamp, etc. This filter prevents dust from gumming up the works (and depending on design) may prevent dust getting into the optics. As the filter gets dirty it gradually cuts off the air and at some point a protective circuit kicks in and turns off the lamp.
If the projector is on you will feel a stream of hot air coming out of the exit vent. Projectors vary in terms of amount of air flow, so its difficult to define what is normal for a specific model. However, you can simply hold a hand in front of the vent and see if there is air flow (It will be hot air so, careful). If there is a "good" stream of air things are fine, but if only a very light flow is felt the filter may be dirty.
If the filter has not been cleaned or replaced recently make sure the projector is turned off and cooled down then take off the inlet cover and remove the filter. Clean or replace per the instructions for the projector (and periodically as defined .. but taking into account the operating conditions). Once cleaned turn on the projector and feel the "normal" air current for future reference.
Heat is one of the major causes of projector failure, so make sure cooling vents (inlet and outlet) are not obstructed and filters are kept clean

SOURCE: Sony VPL-CX6 Projector turns itself off. No image projected.

does the "lamp/cover"-led light up? i had the same thing happening, the lamp either broke or is about to break and the projektor won't turn it on again to protect itself. if its very urgent, open the projector pull the lamp out and put it in again, it might work for 1 or 2 more times, but it is very likely to explode (usually not breaking the projector but for sure not good for it).

good luck!

Turn off on screen message


follow this steps and fix it. God bless you

  • Secure the lamp cover and the air filter cover of the projector body if the projector does not power on. Ensure that the power cable is firmly connected to the projector and an active power plug. If the projector was turned off and then on quickly--let it sit for 90 seconds before trying to turn it on.

  • 2
    Replace the projection lamp if the projector will not power on or if the lamp indicator is flashing. Turn off the projector and let it sit for at least 30 minutes. Locate the lamp cover and remove or loosen the lamp cover with a screwdriver. Carefully remove the projection lamp from the projector housing using the handle, if available.

  • 3
    Place the new projection lamp into the projector housing and secure it to the projector. Replace the lamp cover and reset the lamp timer. Power on the projector to ensure the new lamp is working correctly.

  • 4
    Remove the projector from the enclosed area to allow air circulation if it constantly overheats. Place the projector into an open area and make sure there is no blockage for the ventilation holes. Unplug the projector for at least 45 minutes to allow it to soft reset.

  • 5
    Clean the air filter to allow the projector better air circulation. Turn off the projector and unplug it from the outlet. Remove the air filter cover and use a vacuum to remove dust from the area. If the filter is unable to be cleaned correctly or is damaged, then replace it. Pull the air filter from the projector and place the new one in the now empty slot. Close and secure the air filter cover.

The color wheel sensor needs good cleaning. an optical lens cleaning liquid might help. also clean the fans and vents if you open it. I had to remove the sensor and clean. then it worked.

MY OPTOMA HD65 KEEP TURNING OFF AFTER 1 TO 2 MIN. OF USE THE FAN IS RUNNING WHAT ELSE COULD BE WRONG WITH IT IT IS ONLY 1 YEAR 4 MONTHS OLD ..IT ALSO HAD A NEW BULB


Try cleaning the filter. If the area where it is installed is enclosed this will also cause over heating.. Make sure you have adequate air flow in the place where it is located and clean the filter.

Keeps turning off


So, Shutting down to protect itself. The error light says it needs service, Cycling power makes it work for a few more minutes, then the Panasonic safety circuit shuts it down. Projector shuts down when bulb life gets to the danger zone, and also when its heat sensor says there is a problem.
So you have a bulb life issue or you have a dirty projector / fan cooling issue??

I say clean it up with some compressed air when it is cool, then check the # of hours the bulb has on it (in the menu).

Lastly brace yourself, the bulb is gonna hurt you :-$

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.

The projector keeps shutting off during use. What may be the problem?


I make sure the air filter stay cleaned and no vents are blocked I have had my projector 2 years. I had to send it in last year. And, it went out again today. I hate this projector and would never buy another one. My other projectors lasted 4 years before I had to even change the bulb. I use it everyday all day. They didn't tell me if it was the bulb or the fan. But again today it just quit while I was using it.
