Proxima X350: Lamp Shut Down Intermittently > Upgraded Firmware > Fan Not Working

I have a Proxima X350 that was having problems where the lamp shutdown intermittently and the green LED began flashing. The lamp hours showed only 12-1300 hours which is far below the 2000 hours they claim. In my searching on the Proxima site, I found an "M" version firmware update over the "D" version I had and flashed the X350 with that newer firmware. Now the X350 starts up and within 30 seconds flashes the red LED in a fast double sequence and a notice pops up that the "one or more of the fans is not working ... shutting down". What gives? Did the firmware update kill a fan or is there some incompatibility? Neither the red LED or message had ever appeared before. Or is the new firmware NOW able to detect that a fan is not working (and perhaps hadn't been and was causing the initial problem). Any suggestions? Is this something I can possibly fix myself? If it takes a repair shop, will it be worth it on this old of a unit? Thanks in advance for any help! Jim

    My unit starts up and in less than a minute the lamp turns off and the green light starts flashing. Then after a few minutes, it comes back on, only to keep repeating the same cycle. The manual says it's because the projector can't find any inputs! I've changed between composit and VGA with the same results!

    hey there,
    i m using the XP50 and got the same problem as you described here..

    i thought at first, that - as the error points on - at least one fan is broken, but all three fans are working corretly..
    so i thought, that the speed-pin has any problem (the third cable comming out of the fans). at first i checked the fans on a special power supply unit: all three fans worked perfectly!
    then i checked the fans plugged in the projector:
    the main-fan (which cooles the lamp down) has NO signal! (i checked whith an oscilloscope).
    so at least some hardware seems to be broken .. :-(
    i ll try to trick the check-chip, which seems do be those, on which you plugg the fans and temp-sensors (but this will last some long time!)

    does anyone know the service-code ?

    I was able to use solution #2, but after a few minutes, the machine got really, really hot... I don't feel it is safe to leave it on.

    same problem so i got a small electric fan $10 ,aimed it at the projector and no more probs

  • brightmeadow May 19, 2009

    Bought it used, it seems to connect to my computer and display for 10 -20 seconds, then shuts off.



    After thumbing through the manual, I tried resetting to factory defaults. Didn't fix it.



    Don't have a remote control, wonder if getting one would help?

Hello fellows,
I have the same problem with my projector (Proxima UltraLight X350). I have the firmware v1.34.
On my projector, I found a workarround : if I press the 'top arrow' button on the projector at the message prompt, this one simply disapears and the projector works for hour. The drawback is the red led that don't stop blinking.
Can you cooperate and tell us if this solution worked on your projector ? Please also join the firmware version (found in the service menu, with the lamp life).
Cordially,
Tristan

Hi,

The solution for typical fan failure problem with Infocus ASK M3 / Proxima X350 is the replace the fans and check cables.

Like the projector is saying 'One or more of the fans is not working ... ' so the cables or the fans are little bit worn-out.

The best solution is to get new fans with rpm sensor (3 pins) from shop with same connector or use the old connector.
Also there can be similar fans in old computers and laptops or you can try computer shops.

Alternatevly it is possible to trick the sensor pin from working fan so the projector assumes that everything is ok. (try it at your own risk)

In my case the fans were all blowing and there was no error when they were out in free air.
Once i set them to position and close case the problem appears again.
So one of the fans 50x50x10mm was weak or cables faulty and needed to be replaced.

Similar is 0,99eur on ebay but different connector:

But to make sure its more than 3000rpm, ball bearing and low noise I suggest quality product from ELFA catalogue or some known brand (sunon, jamicon, etc):

Good luck!

I "seem" to have repaired an X350 with the same problem. You'll need a Torx T-8 wrench and a small pliers. Make sure you have a cup in which to place the screws. Remove the Torx screws from the top 1/2. There are 4 and one is shorter, so pay attention to which one that is. Also remove the top connector from the "Computer" connector. Remove the top. Remove the rubber pad from the tops and place it on the bottom where the "buttons" are (nothing sticks up, but they are drawn in). There are 3 fans on the right side. You can flip the pair up to look at them. Plug in the Proxima and turn it on. In my case all 3 fans worked. Blow out where you see dust. If you removed the large front fan, be sure the grommet for the 2 black wires is back in place. It goes in the U next to the fan compartment and the next compartment. The wires go through the hole in the middle. Place the rubber pad back on the top and press it into place. Put the top back on. If you are lucky like I am, it will suddenly work. Good luck!

Firmware flash Proxima X350


Hi,

Make sure the projector is in flash more before connecting. (read flash instructions)
When it prompts for drivers show the uncompressed flasher program catalogue. It should find the drivers for 'Infocus Projector Flash'.
After this you can run the program and continue normal flashing procedure.

Good luck.

Proxima Ultralight x350 no valid input source error?


reset the settings to factory default. if that doesn't work, the lamp may not have enough power to stay on. if the lamp doesn't have many hours on it, it's the ballast.
