Question about InFocus ScreenPlay 4805 Multimedia Projector

Projector turns off after 3 minutes, lamp needs replacement?

Projector turns off after 3 minutes, gives us three blinking red lights. This should indicate the lamp is bad -- but after turning it off for 1 minute (per instructions), the lamp does restrike successfully. We get a picture, but only for another three minutes when we get the same problem. Brightness and image are perfect. It appears the lamp is working properly. We have 2079 hours on the lamp; unit was recently repaired but only the fan was replaced.

    Sorry should have mentioned -- filters are clean, both on lamp and on unit. What does "resetting" the lamp filters mean, something different from cleaning them?

Status light is blinking red, power button orange nec vt700


Hello
Look at the number of blinks of the status light.
[1] If it blinks at one cycle (0.5seconds On and 2.5seconds OFF) : Lamp cover error or lamp housing error. Replace the lamp cover or lamp housing correctly.
[2] If it blinks 2 cycles (0.5 seconds ON and 0.5 seconds OFF): Temperature error. The projector is overheated. Move the projector to a cooler position.
[3] if it blinks at 4 cycles (0.5 seconds ON and 0.5 seconds OFF): Fan error. Fans sill not work correctly.
[4] If it bliks at 6 cycles (0.5 seconds ON and 0.5 seconds OFF): Lamp fails to light. Wait a full minute and then turn on again.
[5] If it blinks continous (Red): Lamp has reached the end of its life. Lamp replacement messege will be displayed. Replace Lamp with same type and number. After replacement reset lamp hour. OK.

Hi,
If red light blinks 3 times when tv refuse to power up then check lamp cover that was removed to replace lamp, make sure lamp cover is fixed in its position securely and screw is tight.
Let me know how many times red light is blinking after three second long pause IF it is not blinking 3 times.
Thanks.

The lamp still does not light up after the new lamp installed? Or the lamp is working but the Red lamp still blinking? Reset the lamp timer after the lamp is installed?

Won't piwer on


Tried to turn it on? Sounds like you need to replace the lamp. However, I got an additional week out of my unit. Although poorly dimmed and the red Lamp light blinked constantly for that one week, at least it gave me enough warning to seek out a replacement. But so long as you're not mistaking the Power/Standby or Timer light for the Lamp light then I would have to agree with you. http://store.l-f-l.com/prod/A-1606-034-B Includes shipping to the United States and no sales tax outside of California.
