The heat is generated by the lamp whether or not there is an input signal. If the unit seems to be hotter than normal, check the air input grill and be sure that it is celar of dust and debris. You can also gain access to the fan and be sue that the fan is clean.

Hello.. My projector came on minutes ago now the light is just blinking. Can you please help? I have a Sony vpl-es7


You might check the following:

* signal is going to the input. If not, does the menu come up?
* air flow is ok. Projectors don't run well if they are hot and can't breathe

PT-AX200U. How do I repair or replace a non-working fan?


Is the fan turning? It may just be the air filter is in need of cleaning. If it is not turning at all then turn it off and keep it off until it is fixed otherwise you may cause the lamp to burn out prematurely.

Infocus in104 projetor problem: power off, temp red, lamp green


Most probably failure of the thermistor or thermal fuse that detects the temperature of the lamp housing - so the projector thinks it's hot even when it's cold. Unfortunately it will need a trip to an authorised service centre for repairs

Purchased 2006. Ceiling mounted. Just stared overheating after approx 10 minutes after last bulb replacement in March of 2010. Floor fan pointed at projector helps. Tried cleaning. Running right side...


Yes, if bulb was low price and was installed in old lamp casing then it is bulb that is not good and creating too much heat that exhaust fan can't throw out to make projector cool enough so temp sensor activates and send over heat signal to system control chip thus projector shuts down.
Please install original lamp that comes with casing to solve this issue.
If lamp was original then check exhaust fan that might be running slowly due to stiffness in bearing so temp sensor finds over temp in projector.
Hope these info will help you.
Thanks.

Our Infocus sp5000 is shutting down because it is getting too hot. We had just cleaned the filter.


you also need to clean out the machine with canned air. also check to see that all of the fans are running. if they are not all running, they need to be replaced. also, the temp sensor near the lamp housing may also need replacing.

it might be dusty enough to hold in the heat. it needs a good cleaning. use canned air. if you still have an issue, the fans might be running too slow or the thermister (temp sensor) may be faulty. sometimes if it gets too hot in there, the thermister needs to be replaced, too.

i believe your problem is heat the bulb is getting hot and the air or fan is not working properly so when it hits temp it automatically shuts off check your fan air flow filters etc

Sanyo PLC-XF46N projector shuts down before powering up completely


The Fix Ya rep suggested that I try the "Reset" button located next to the Audio out on the side of the projector; this solution proved to be the fix I needed. I was able to get the lamps to warm up and get into the menu to cut back the bulbs/power consumption on start-up, allowing the projector to function for a problem-free 4 hour period Unfortunately, I had the same issue this morning, but the same fix worked again.

Startup issue


Either the lamp needs to be replaced, or your projector is experiencing overheating problems.
The unit may not be running hot but there may be a bimetal thermal switch that has become fussy.
If you have an electronics supply nearby, they will have 'freeze spray' and if you procure it, you can see if the projector will turn back on if you give it a shot in a vent. Do NOT spray it on a hot lamp; it may cause it to fracture. If this does make it turn back on, you will have to locate the failing switch although the common ones are disc-shaped with two contacts coming from them.
