Question about InFocus ScreenPlay 7200 Multimedia Projector

7 Answers

Fast flickering Greenish orange light w/ clicking noise, no power up, unresponsive

This problem is well documented on these boards but I have yet to find a solution. It is not specific to these InFocus models as I have a Toshiba TDP-MT8U which is experiencing the exact same problem. Which I believe is due to the fact that Toshiba outsourced these products to InFocus for production. One day the unit worked fine, the next day when I went to turn it on it was unresponsive and I noticed the flickering greenish-orange light. I tried the unplug and plug trick many times to no avail but one day it came back to life. 3 weeks later the same problem has resurfaced. I have found at least 15 people on FixYa listing the same problem with various InFocus and Toshiba models, all of which look the same from the pictures. Any help at all (besides spending another $400-600 getting it repaired at Projector Doctor) would be appreciated.

Thanks,
Elad

    Here are more examples of the same problem:

    These are all on clone units I believe.



    I have checked and the lamp is secure and the fans usually come on but it is somewhat hard to see. From what I can tell they always attempt to start running but sometimes they start and then stop almost immediately.

    I cannot reset to default settings because the unit is nonresponsive and will not power on.

    The fans are no longer starting up. I have tried plugging the unit in different outlets and also using different power cables but neither was successful

    "may be your power supply earthing is not porperly.
    check your projector in other place where earhing prol;per.
    also check with other adapter."

    I am not sure I understand what you are trying to say here, can you please clarify?

    "Hi,
    The problem is with power supply..and the battery seems dead and the sensor cant read the charge level of the battery as its faulty resulting in the orange and green flash."

    If this is true would this be something I could fix on my own or must i send this to a repair center and pay through the nose? Keep in mind I do not have extensive experience with circuit boards or anything like that but I have put together a computer so simple replacing and connecting is doable

I think best way is to take it to an authorized service station to troubleshooting and estimate the cost and parts need needed to repair circuit. Normally the cost will be reasonable.
To troubleshoot yourself and replace components is difficult if you have no previous experience in repairing electronic printed boards and you must have at least some basic tools and instruments.

Flickering is a signal issue....but overheating can cause the lamp to try and work too hard....kind of that limbo between where it ACTUALLY gets too hot, and when the sensors determine its too hot, and shut the unit down. I used to have two projectors that distinctly flickered when they needed their filters cleaned. After I cleaned them, they were fine, for another couple months. You are right though.....at elast 85% of the time....flickering is a signal issue.

Thanks

    The multimedia projector is a very compact device. If you open it there are lot of thin wires and integrated chips on the main board which can get damaged. I would rather suggest you to contact Bestbuy\Geeksquad and let a qualified technician replace it for you. They will not charge you much.

The soldering of the small electrical components on the main board has got loosed so it is working sometimes and fails to work sometimes.get the cold soldering done on that board to make the soldering firm to hold the board tightly and then check it should work.

    if you have the proper tools and instruments and have the proper technical knowledge you can do it your self or taking it to the repair center is much advisable to avoid further damage and trying to do it on a risk.as the problem what you r facing is faced by many users and is repairable .



    thanks.

Check whether the lamp door is securely closed?

Does the fan operate?

There is also chance of bad power supply .

Have emachines monitor which is not coming on power button fast flicker


Which power button is flickering (your computer, or your monitor).
Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.

Mouse unresponsive and red light flickering. you have to click the mouse to make it responsive again.. but if you leave it a little while the same procedure again


It sounds like the mouse goes on standby to conserve battery power, or the batteries are getting low. It's more likely it goes into a low power mode to extend battery life and conserve power.

Pilot light seems to high


there may be an adjustment screw for pilot height. you'll have to look at the valve. a pilot should have an inner cone of greenish blue color and the surrounding flame should be a deep blue no yellow or orange tips. the pilot burns pure fuel no air. the main valve does mix air with the gas in order to burn.
