Question about InFocus IN1503 DLP Projector

1 Answer

My infocus 1503 works however once it is turned on the unit sounds as though it is ready to take off. The fan is very loud then after a few minutes it quiets down and then the fan becomes very loud again. It will continue until you shut it unit off.

    I own two of these projectors. You need to update the firmware to 1.03 which can be found on the infocus website. This solves the fan issues which also causes premature shutdown of the projector. Once you download the update, open it, there will be step by step instructions on how to do this procedure. I could not get this to work with Vista 64 so you might need to run this on XP or 7.

    Any idea how to proceed when the update cannot be applied because the machine turns off too soon? I seem to have this fan issue also.

SOURCE: Fan noise loud, bulb burst. Replaced with new bulb. Noise even louder! Unit shuts itself off.

the bulb may have burst from overheating from a fan not working to cool it down. and it can be replaced. it does take, however, a while to replace it because you have to take half of it apart. but make sure it's the fan first. take the lamp door off and remove the lamp. use something small and thin to push in the switch that the lamp door usually activates. turn the projector on and see if the lamp fan and the colorwheel (the multicolor glass disk) are spinning. if the fan spins, the noise may be from the colorwheel motor going bad. the fan can be purchased through an infocus authorized service center. check the website for the closest one. but the colorwheel for the x1 cannot be purchased seperately from the optical engine, and that costs a fortune. but here is the part number for the 80mm fan- 526-0152-00.

InFocus litePro won't turn on.


With a bit of luck a fuse may have blown though almost certainly the lamp has gone. Never **** the projector when the lamp is on.

Infocus x1 noise problem


the colorwheel motor does burn out after a while (from heat and dust), but as long as it spins at the right speed, you won't see a problem in the image. if it's making noise, it's going to go soon. it does need replacing. however, infocus does not sell individual parts for the x1 optical engine. you will need to replace the entire engine, which costs up to $2000. so, enjoy the last few hours with your machine and look into getting another.

Infocus x1 projector


Indeed, the problem you describe is the Color Wheel. Very common issue in the X1,2 projectors. Unfortunately the only fix is to replace this wheel. The cost of the part generally runs around $175 but the labor to replace is about the same. You will need to find an authorized service center where you live or send it to a repair facility. Parts for any of the InFocus units are generally not available to the public, alas the Service Centers. Maybe for the same cost you could look at a new projector, like I did.

TV screen flashing on and off


This is what I found on mine. There are three wires powering the fan. They routed beside and under the fan. They are separated from the cooling fins by a bakelite(?) material. There is a shrink sleeve around them. I noticed the shrink sleeve was brittle so I cracked it with a pair of pliers. When I did I found the insulation was off of the wires and they were together. I cut the wire and re-routed them around the two prongs that hold them against and under the fan. The fan worked and my problem was solved.
I contacted Infocus and they acted as though I were talking Greek to a Geek. Hope this Helps.

Over heating


you trouble shoot the problem by opening unit and force-powering fans to test for overheating during "being used loud for a few minutes". Read the fans' label for proper voltage to apply and proper polarity. I am guessing the fans will run on car battery voltage of 12 volts. Also, attempt to close up the unit to simulate real conditions. There should not be fuses for the fans. If unit is now cooling, then look for faulty thermistor, which turns the fan on during rising temperature. Once thermistor is located, a fast test is to "jumper" its two wires to simulate turn on.
