Question about Canon LV 7345 Multimedia Projector

1 Answer

Projector turns off after 35-40 minutes

This Projector was recently intergrated into a new system that runs eveything through a switch plate in the front of the Auditorium. The System allows you to turn on the projector and then select computer or VCR/DVD. It seems to work fine except that the projector will turn itself off after 35-40 minutes...whether its on the computer or VCR/DVD mode. I sat and watched the projector and saw no signs of overheating. I even cleaned the air filters. It has done it each time we have ran it..5 times so far. Any ideas why it would be doing this?

    I've had the same problem before my projectors. I have two types... Epson 835P and Epson 7800... My solution is usually to just clean the air filter... but there was a time where it had a bad heat sensor and I just took it to get replaced since I had warranty with Epson. Maybe that's your problem :(

    Good Luck! Let me know what you find out.

How are you wiring it up? Yellow, White Red (RCA?) or Red Green Blue? or SVideo. Also make sure your projector is switched to the appropriate input.

We have recently fitted a new lamp. I followed the instructions "replacing the lamp uni" then the "resetting the Lamp Runtime" instructions. It worked perfectly for 19minutes, then the lamp turned off,...

I think thelamp is running hot and shutting off due to the thermal cut off. So try to cool the system with a forced fan cooling and see if the projecctor runs for more time. Also see if the filters have choked and is not ventillating to the lamp resulting in the heat buildup. I sincerely hope this could be the fault as in cold condition it had worked longer.I hope this helps. Good day

Hitachi ED-X8250 - Turns off after 15 mins LAMP and POWER = RED

try looking for your thermistor usually located near the wind path its a small block the size of two match heads usually mounted off the main board with two wires this is your 'heat switch' so to say, also check your fans are clean and running there is normally more than one.

Infocus IN1 Gaming Projector

Hi, I just bought the same projector Infocus IN1 and after just 15 minutes of use it turned off due to overheating. It seems that the lamp is very ineffecient and produces too much heat. The ambient temperature in the room is only 16 deg. celcius. 

The solution I came up with is to have a standing fan blowing air directly on the back of the projector from less than a foot away. The standing fan which we usually use here in summer was enough to keep the projector cool. The infocus IN1 did not switch off for the next 2 hours (the entire length of the movie), until i turned it off myself. I am not sure how this system will fare in summer when the room temperature reaches 30 deg. celcius.

Yamaha LPX 500 home cinema projector isn't lighting up

The reason for a red light is replacement of lamp or it is running too hot. Have you checked for proper venting, and cleaned them recently. The bulb usually lasts 2000 hours, so you may need another.
