SOURCE: infocus x1a fan replacement

to remove the fan: remove the 8 screws from the bottom of the projector (4 silver, 4 inset and brass) and the 2 screws from the back. pull the back from the bottom, but use a small flat-head screwdriver to release the tabs seen through the topmost vent of the back. once off, unplug the speaker wires on the right and the cable harness on the left. pull the top off while pulling the front off from the bottom. remove the wire harnesses from the power supply board and the ground wire from the power input board. take the 4 screws off of the power input board and the 4 or 5 screws from the power supply board (and 1 center clip) and remove. take out the 4 or 5 screws from the metal shield and remove shield. now you can unplug the fan that need replacing and access the 2 screws holding the fan in. remove fan and replace with a like fan. since the fan speed is not monitored, if you can find one that's the same size, power, and plug size, use it. otherwise, contact an infocus service center and ask them for infocus part # 526-0192-00. reverse instructions to put it back together. but you must remove the front from the top case, put the top on first, plug the speaker and left harness in, then put the back and front on. wasn't that fun?

SOURCE: One fan has become unbearably noisy. Need

Hello there karlskad8.

Here's your geek-steer ...

Do NOT pass go, do NOT collect $200 ... you need to IMMEDIATELY replace that particular fan before you fry your CPU chip! Stop using it until you do!

If you plan on do-it-yourself, refer to your user's manual to possibly get replacement part order info. Otherwise, call a local PC shop and ask for the info.

I prefer for all my fan related needs.

Good luck, and please do post back ...

  • to let me (and interested others) know how things worked out,
  • to provide clarification or feedback,
  • if you have ANY further questions.
Today's the best day of my life ... and NOW you're part of it!

SOURCE: Replacement of Fujitsu Lifebook N6420 cooling fan

Note this procedure is specific to the N6420, but may work on other N series Fujitsu notebooks. I generated this solution by a step-by-step process on my N6420.

Procedure for replacing (two) cooling fans on Fujitsu Lifebook N6420. This procedure was required because of fan bearing noise, indicating potential failure of the fan in the future and the noise was very annoying. I performed this procedure after about a year of bearing noise and after not finding any reliable procedure on the web. Fujitsu offered to replace the fans for $230 - far more than the laptop is worth at this point. Below is the correct procedure for the N6420 and specific to that machine.

You will need to purchase two cooling fans Toshiba Part Number S6055AM05. Be sure and purchase the ones with metal backing on one side of the fan. You can find them on eBay for about $10, but beware of what you buy. Recommend you purchase new OEM fans and not refurbished fans as they may not come with the thin metal heat transfer plate provided on the OEM fans. Some of the knock-off and refurbished fans do not include the metal backing, heat transfer shield. You will not need thermal paste.

Note: All of the other instructions on the web I found for the N6420 were incorrect and seemed to be lifted off some other notebook. I actually performed these instructions and made sure they are accurate.

Note: While you wait for the new fans .... and you must use your N6420, but want to buy yourself a little time before the fan(s) totally die ... you can try this procedure at your own risk ... and spray a very small amount of silicone lubricant between the fan electronics and the spindle - this area is easy to indentify if you hold one of the fans on its edge. The use high pressure air spray to blow out any grit, dust and silicone overspray - wipe each fan with a clean cloth. This little bit of lubrication and cleaning made the bearing noise go away. Both fans are spinning up ... but, I ordered new fans anyway to make sure the notebook would have adequate cooling and to preclude the old fans from going bad and causing catastrophic overheating.

Here is the fan R&R procedure itself:

- Shut off the notebook and disconnect all peripherals

- Remove cover to RAM (optional)

- Remove Battery

- Remove HD Cover and HD(s) (I have two - some may only have one)

- Remove 15 retaining screws

- CAREFULLY - Remove base/bottom notebook cover, take care on the side with the PCMCIA slot, USB port and sound ports

- Note orientation of the two fans so you can replace them the same way

- Now remove the two old fans (two screws)

- Install the two new fans

- Replace two screws under HDs

- Replace two screws under battery

- Reinstall the base cover - take care on the side with the PCMCIA slot, USB port and sound ports

- Replace the remaining base cover retaining screws

- Replace HD cover and its retaining screws

- Replace RAM Cover

- Make sure you have no/zero retaining screws left (all 15 screws and the HD cover screw are identical)

- Restart Notebook and get back to business

One of the relay boards is a downdraft relay board....I would be suspecting the main clock assembly as it is the one that shuts down and controls everything. This might also increase the fan speed randomly, turn it on at random temperatures etc., You have to get a new board. You can find it here

I have a gateway one zx6900 cooling fans make a lot of noise. How do i fix this?

Replace the FAN. You cannot FIX these. REASON> The fan motor generally turns on a ball bearing or oil impregnated sleeve. These tend to dry or wear down from use or age.
They are low cost devices and replacement is the only way to go.

IN5532, problem: Indicator power on (green) Indicator service: on (red) Indicator lamp: blingking (red) Please, what kind of this problem indicated? And how to fixed? Thanks

Power - green - is good.

Service - red - is not so good

Lamp - blinking red - is not so good

For dual-lamp projectors, one blink off every 2

seconds means the problem is with lamp #1; two blinks off
every 2 seconds means the problem is with lamp #2.

So how many lamp blinks do you have?

How to install a fan in a KODAK carousel projector.... fan is noisey

Chances are that it isn't the fan in your Carousel Slide Projector that's noisy, it's a stretched-out fan belt. While there are still parts available (, to complete this repair is pretty much a total tear-down of the projector. Unless you have been in a projector before (and have a service manual), you may cause more harm. I would recommend finding a factory-trained repair dealer to do this for you.

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

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.

    Noisy Wine Fridge

    The problem is likely with one of the two fans. A new fan is available from Danby (1-800-263-2629). My noisy fan is the condensor fan located at the bottom rear of the device. After removing the cooler from under the cabinet, the source of the noise was obvious. You will need to tell them whether it is the upper fan or lower fan. Leave the cooler upright for a few hours before you plug it in so that you do not damage the condenser. Price for the fan from Danby is $20.15 including shipping. Users Manual is available at -Ron

    Projector will not power on

    Check your cooling solution wether its a fan malfunction or if it needs a new fan - or h20 cooling system

    if not its either the power supply or something serious - send it to manifacture or go to a in-store repair

    (it could be the dust protector)
