InFocus IN74 Projector Fault

I have the abovementioned Projector. All of a sudden yesterday I turned the Projector on as normal and then about 20 seconds later the picture was gone and a red light has been flashing since.

I have tried turning it off at the power point and back on again and the same thing keeps happening.

Could you please offer some advice as to how to fix the Projector or what may be faulty?

    We had a red light flashing and no picture. We unplugged it and then the green light came on blinking, the picture came on for about 20 seconds then stopped and the red light started flashing. We unplugged it and then plugged it back in again (after waiting about 10 seconds). This time smoke poured out of the projector. Any ideas on what happened?

Hi there.

How many hours had it done? The bulb may have expired and as a safety precaution the projector will not switch on, otherwise the bulb will explode causeing further damage.

Was it mounted on the ceiling? There is a power supply/ballast board inside that goes bad. I have seen some where the board is actually burned on the other side from where the ballasts are. Chances are the bulb is fine but the ballasts failed. Other symptoms are dim or flickering picture with low hours on the bulb. This is a well know problem with these projectors but infocus wont do anything about it.

Projector shuts off, and the start-button light blinks red in 3-blink sets. Unplugging and plugging back in then hitting start button gets it going again. What is the problem?

Does it switch off after being used for some time?
Actually, from your question it is not clear. But you can open the cover and check for dust, specially at the air filters.
Most used projectors have this problem. If the air filters are blocked with dust, the the projector will overheat and switch off.

Turns of suddenly

see what the leds on the top are doing. what colors? are they blinking or still? if they are blinking, how many times? this will let you know what the problem is. shortcut: it's either the lamp is close to 2000 hours, it's overheating (dirty or no air flow), one or more of the fans are bad, or the power supply is not sufficiently supplying power.

InFocus LP280 problem

Hi there

I'm afraid this might be a faulty Mainboard.

Your lamp will never make the Projector show funny stuff on the image.

Must warn you that a new Mainbaord is quite expensive
