Projector is not turning on...and turns off when on

My projector is starting to act crazy. I have to hit the on button atleast 20 times to get it to turn on. While it is on, it will turn off automatically. Sometimes the projector acts like it is getting no power and wont turn on or make the beeping sound that tells you it is turning on.

If the lamp is good, it could be a fan not working, which would be a bad fan or bad main board. IF the fans are working, then I would have to say that the power supply was bad or the fan laying flat against the bottom in the right rear corner is bad.

Theatre projector is unable to switch inputs in menu


This is worth a try: Turn everything OFF. Unplug all the inputs from the projector and turn them off too. Next, turn the projector ON and all the input devices ON. Then, one by one plug each input device (already turned ON) into the projector. See if this helps. I have a SONY monitor that supports multiple inputs and a few times this has worked.
Good luck.

I have my G60 laptop connect to an LCD projector. I wanted to turn off the screen on the laptop and hit Function F4 which i have done in the past and it took the picture off of the LCD projector and now...


Disconnect the cable that is connecting the laptop to the projector. Sometimes this will happen if the projector or device you're connecting your laptop to does not support the current resolution that the laptop is displaying. Reconnect the cable and try using Function F4. If that does not work then disconnect the cable from laptop to projector, reboot the laptop then repeat connecting it to the projector and pressing Function F4.

I need to reset my lamp counter on my projector pt-lc56e but i dont know how please help me


After changing the lamp you should be able to turn on the projector and it should run for approx. 10 minutes, allowing enough time to reset the lamp counter. Hit "Menu", select "Option 2", hit enter, which will bring up "Lamp Runtime", press and hold enter button approx. 3 seconds. The selection will change to "Time Reset (Power Off)". Turn off the power and it will reset.

Can't start infocus sp7200 after changing lamp.


The end of lamp timer has reached it's limit and won't let the new lamp strike. What you need to do is Reset the end of life timer. To do this, with the projector switched off press and hold both the up and down Brightness buttons on the projector. while holding them in turn on the projector. Continue holding the buttons in for 10 to 15 seconds This will reset the end of life timer in the projector.


Cheers

Both Temp and Lamp lights blink red


All you should need to do is go to the menu on the projector, and find the Filter Timer. Hit the right arrow to select the filter time, and then hold the rest button on the projector until you are prompted to confirm the reset. Hit menu to confirm and it should now reset the filter timer. Now cut the projector off and back on and the lights should stop blinking. I hope this helps.

Wont start up


Hi,

Pls clean the filters and check the lamp by opening the lamp cover. If lamp looks okay in all aspects then send the projector to any engineer to check the ballast unit of the lamp.
