Question about InFocus Play Big IN76 Multimedia Projector

2 Answers

When I turn the projector on, it goes about 2 minutes, the picture (lamp) flickers and then it shuts down. I can pull the power cord and when I plug it back in, it will start up again but repeates the shutdown. The lamp has just under 400 hours on it. When it was new, the power supply failed and was replaced under warranty. Any ideas? Glenn Nellist gnellist@fmtcswb.com

This is a little late but these models had an issue where they would over heat and even catch fire. Infocus ignored the problem. I need a new power/ballast board for mine. Look at the videos on YouTube to see what happens to these boards. Search for IN74 fire.

I also had the same problem and finally we heard some glass shattering sound. I opened the projector cover and found signs of burning and one part separated ?diode or what I do not know. I can see a small hole on the board possibly where the wire got broke and the piece became separated and resulted in a shattered noise, I suppose.

    It sounds like the power supply board is faulty. I think they may be out of production now which is a pain. The component that fires is a capacitor, C512, if I recall correctly. Replacing the capacitor may resolve your issue. I think its a .47uf 450 volt metallized polyester if I can recall correctly.

    I've just found an old supply and the value written on that cap is:

    474k450
    NIS V02
    This may work, I don't know, good luck!

Benq MX761 stays on for only 2 minutes and then shuts down after genuine Benq lamp replacement. Picture flickers colour just before shutdown. Lamp timer has been reset to zero.


Many LED TVs and other electronics have bad capacitors on their power supply boards. You can visually inspect them by opening the TV and looking for capacitors with bulging tops. If you see any, replace them all in the power board section. Check to see if your TV is still under warranty first though.

Projector powers up, after 2 minutes image goes away, projector goes into cool down, then shuts off. why?


FAULT: lamp of your projector is faulty.
Experience: when lamp life is near to end and environment temperature is too low you are facing the same problem and if you are facing this problem in normal temperature then also lamp is faulty.
Sulotion: Just replace the projector lamp

Hello :

Try to change the bulb .

Here is how :


1:Make sure that your power switch is off and that the power cord is unplugged from the electrical socket.
It is also wise to unplug any other cables and label them in order to restore them in the right way once the lamp is replaced.


2:In order to see the lamp, remove the access handle on the outside cover. You may need to use a screwdriver.

3:Pull out the used lamp and clean the relevant parts using micro fiber products and not paper.
Please note that in some projectors a small inside filter should also be replaced.


4:Insert the new lamp into the projector carefully avoiding touching the glass of the lamp itself.
Touching the lamp will deposit skin oil that will likely damage any new lamp during use.





5:Reassemble the access panel, replug the cables and power up the projector.

Things You'll Need:
new projector lamp
screwdriver
micro fiber duster
Warning:
avoid touching the bare projector lamp.

please rate !

Hp projector


This is caused by the color wheel sensor failure. The sensor is mounted very near the lamp and suffered extreme temperature. This problem can be corrected by installing the redesigned color wheel sensor. You also need to refocus the sensor due to different focal length. HP also recommended to replace the temp sensor cable. If you still have the projector, I can fix the problem for you.
