No Sir, Main power supply has 2 portion, 1st is called primary and 2nd is called secondary. Primary power area is connected to ac oulet directly and secondry power area is isolated and source of power to projector circuits. Lamp power supply calls "Blast Power Supply" in projectors (Its very high voltage area). Please be careful while testing power supplies.

Turns itsel of after a few seconds


Not the lamp - if it were the lamp it would never turn on in the first place! Check for a defective component in the power supply area especially the capacitors. When their value changes, they are responsible for all kinds of erratic behavior. Items will not turn on, shut down after a few seconds, etc.

I have a Infocus in1503. It shuts down after 10 to 30 minutes. When it does shut down there is no lights. In fact the power light goes off as well.


I seemed to have had the exact same problem... I had placed the projector on top of a small book (to raise the unit), however, did not rest the feet of the projection unit on the book and it overheated and turned off, as a result. (The bottom of the unit was making direct contact with the book which caused it to overheat since not any air was passing through between the two)

After letting it cool for a while and powering it up -- it would usually power off completely for about 15 minutes. After a little thinking, I thought it may be the lamp/bulb and waited a couple of years and bought one online that arrived yesterday.

I installed the new lamp/bulb this morning and it did the same thing. It powered down about a half hour later. Bummer.

I reset the machine to factory defaults and checked to see if it had the 1.03 firmware... It did

Then went through the settings in the setup area and turned off the 'prevent pic screen saver'... Reset the 'lamp hours'

I doubled checked the lamp/bulb installation... Turned it back on -- same thing -- it shut off after about 15 minutes or so... Then unplugged the unit and turned it over and took out the 4 or 5 chassis screws and loosened and took off the side panels and blew onto the fans and circuit board areas and gently pounded the sides to shake anything that shouldn't be there loose and put it back together.

i powered it back on and now it's been working for about 2 hours and 16 minutes!

good luck!

Hello! I have a DELL 1209S that the picture is wavering. Is it spring?! Some vertical lines almost invisible in the background are also perceived. What can it be?


follow this steps and fix it. God bless you

  • Secure the lamp cover and the air filter cover of the projector body if the projector does not power on. Ensure that the power cable is firmly connected to the projector and an active power plug. If the projector was turned off and then on quickly--let it sit for 90 seconds before trying to turn it on.

  • 2
    Replace the projection lamp if the projector will not power on or if the lamp indicator is flashing. Turn off the projector and let it sit for at least 30 minutes. Locate the lamp cover and remove or loosen the lamp cover with a screwdriver. Carefully remove the projection lamp from the projector housing using the handle, if available.

  • 3
    Place the new projection lamp into the projector housing and secure it to the projector. Replace the lamp cover and reset the lamp timer. Power on the projector to ensure the new lamp is working correctly.

  • 4
    Remove the projector from the enclosed area to allow air circulation if it constantly overheats. Place the projector into an open area and make sure there is no blockage for the ventilation holes. Unplug the projector for at least 45 minutes to allow it to soft reset.

  • 5
    Clean the air filter to allow the projector better air circulation. Turn off the projector and unplug it from the outlet. Remove the air filter cover and use a vacuum to remove dust from the area. If the filter is unable to be cleaned correctly or is damaged, then replace it. Pull the air filter from the projector and place the new one in the now empty slot. Close and secure the air filter cover.

As indicated in the post, when switching on the projector it switches on for 1 to 2 seconds and the overheat lamp goes and the fan goes into 'overdrive' - really fast and loud. There is only 300...


Hi, I assume the temp light is coming on solid and not flashing, hence indicating overheat, please let me know if my assumption is incorrect and check link below for light meanings

Firmware have you checked it? It is the brains behind the unit, firmware is modified ever now and again by HP to improve on faults found in the field, early release models had a few problems that are rectified by updating firmware by hookin the projector to a pc by usb and downloading the file I have posted a link to

You should check your firmware version. Version iinfo is found on the on screen menu then choose help. Update if it is lower than ver 2.012 as there was some issues with temp corrected in early realeased firmware. Link to latest firmware and firmware Installation Instructions and previous version issues


If that fails then theres not a lot to tell you, either the thermistor that sensors the temp is faulty or lamp or electrical components like the lamps fans resitors, transistors, capacitors, transformer etc in the machine is playing up giving off too much heat or misinforming about the presents of heat, you could ring HP and try to blame the lamp which is covered under warranty on these for like two years but I'd guess they would tell you to check the vents and filters and take it in for repair, which is really all I can tell you too as these types of electrical gear are not safe to be pulled apart and played with as they carry some punch in circuits to drive that bright lamp

I Hope it is early firmware just causing the issue for you otherwise I guess it really needs to go to hospital.

Let me know if you need some more info or if I misunderstood your issue

Cheers

Steve

Hi!
Is the projector placed in a box or an area where it could generate overheating? Is this projector still within warranty?

How do i find out if i need a new lamp for my infocus 4805. when i turn it on the fan blows for a cpl secs and the green light blinks a few times, but i dont get anything saying the lampis out


when you power it on, do you hear a high-pitched whir? if not, you need to replace the colorwheel. it's also the colorwheel if you hear a buzzing instead. if the colorwheel does not spin, the lamp won't come on. if the colorwheel is ok, check the lamp. is the screen on the side of the lamp clogged with dust? is the inside of the lamp bulging, spotted, or foggy? if so, replace the lamp and clean out your projector with canned air. dust blocks air flow and keeps in the heat. this shortens the life of your lamp and projector. if you do need the colorwheel replaced, you could get the part from an infocus service center and do it yourself, or send it in for repair. either way, try av solutions in ny. they're really good. www.avsolutionsny.com
