Question about InFocus ScreenPlay 5700 Multimedia Projector

Open Question

Infocus 5700 - possible lamp failure, how can I tell?

I bought an InFocus 5700 projector from eBay, it seems to be in good working order as when plugged in the LED turns green and then when the power button is hit the LED flashes green- as explained it should in the manual. However after a few minutes the flashing green LED changes to a flashing red LED. As in the manual I have counted a two second interval between each flash and there is only one red LED flash per sequence, this suggests that "the lamp wont strike after 5 attempts" as the manual states for this error sequence of flashes.

Based on other forum posts I have checked the lamp door and the it is correctly sealed with the door trip switch in working order and switched "on". With this in mind I can only think that the lamp has blown. However it was sold to me on the basis that the lamp has only 200 hours, so it should be fine.

Inspection of the lamp has me wondering. In the silver part of the lamp there are two holes each with a small metal ring around the hole. Only one hole has a filament wire coming from it to central column in the lamp whilst the other hole is empty.

Does anyone know if there is supposed to be two filament parts, one coming from each hole or even better can someone send me a picture of an intact bulb? If I can gather as much information about how to inspect the bulb for if its blown as possible, it could save me £300 should it mean I don't end up buying a spare bulb I don't need!

thanks

Are you speaking of the small prism shaped tunnel or the lamp itself? The prism or light tunnel may be accessed underneath the metal bracket that holds the color wheel in place. Be extremely careful as even breathing on this may cause it to collapse (ok, I exaggerate).

If the counter expired, then the reset is holding both volume keys down for 10+ seconds.

SOURCE: lamp didnt strike

Hi there

You should reset the lamp timer as this LCD Projector's counter counts down the hours and will not fire up if this has not been done.

If you have reset the lamp timer and the problem stil occurs , you'll have to replace the Ballastboard ( lamp's powersupply )

Usually when the lamp is good and you get this message, the ballast is bad. That is the part thatdrives the lamp. Check with Infocus for a repalacement balast.

SOURCE: Infocus LP820 - Turns on for 30sec then shuts down

This could be one of two problems I have seen with another model Infocus projector (they are very good projectors though)

The first is the video input. Make sure it is attached correctly at both ends of the cable.
The second, remove the dust covers and blow them out. The problem can arrise if the temperature sensor detects the air inside the unit is getting too hot. If you can see the sensor when the dust covers are off (it will look like a little lump of goo on the end of a wire) then just give it a wipe as well. If dust settles on those it can cause incorrect temps to be reported.

Hope that solves your poblem =)

Possible fault on the mother board as there are noise on the LCD display. You might need help to sort this out if the fault does not clear even after the lamp works for some times.

My Infocus 4805 is just showing the INFOCUS logo and not showing the picture from the TV. all connections are correct but no signal....help


Powering On
  • If your InFocus 4805 projector is having a hard time powering on or doesn't power on at all, it could be one of two things. Due to the extreme temperature of the lamp that causes the temperature of the projector to rise, every InFocus 4805 projector has a cooling system. Check your projector's cooling solution, as it may need to be replaced. Also check the projector's fan---if the fan doesn't spin, the unit will not turn on. If the problem is the fan, you'll have to get it replaced. You can do this at the same place you bought your projector.
  • The Lamp
  • If your InFocus 4805 Projector powers on but does not project any light, the lamp will need to be replaced. All projector lamps must be replaced at some point---how often usually depends on how much use the device gets. Simply order a replacement lamp, unscrew the old one and screw the new one in. The projector will then work like new.
  • Color Wheel
  • If your InFocus 4805 projector powers on and is displaying images but the colors on the images appear warped or are not in the proper places, your "color wheel" will need to be replaced. The color wheel is a small device that essentially acts like a prism. Light is projected through it and it displays the appropriate colors on screen the way they appear in the original video source. Order a replacement color wheel that fits your model and use your instruction manual as a guide as you swap the old one out and put the new one in.

    the lamps are good for about 2000 hours. but it sounds like it's time to get a new lamp. but after you put it in, go into the menu and reset the lamp timer.

    if the lamp is relatively new, the colorwheel might be coated with dust. the heat bakes it on. you can try to clean it, but you might end up having to replace it. try av solutions in ny. they're pretty good.

    InFocus LP120 Powercycles/Shuts Off/Does Not Stay On


    what is the led doing? what coloris it? and if it is blinking, how many times? this will tell you the problem.

    green (flashing and solid)- all is well
    red flashing:
    1 time- lamp won't strike after 5x
    2 times- lamp has over 2000 hrs. replace lamp
    3 times- lamp failure. replace lamp
    4 times- fan not working.
    5 times- projector running too hot. needs cooldown
    red led lit solid- undiagnosed issue. send in for repair.

    if your projector is under 2 years old, it's under warranty, but it seems unlikely.

    Infocus 5700 new lamp unit makes variable blowing noise


    it will speed up to increase the air flow if the temperature goes up, and slow down when it drops. it's normal. that's how it maintains a good temp.

    Lamp won't stay lit


    I've got the same problem, I'm wondering if it has to do with some sort of auto shut off kicking in due to overheating or something, I was gonna try replacing the fan to see if it's something to do with that
