Power Board for and Canon ipf510

Ok, this is a little embarrasing. Purchased a Canon ipf510 in the US and had it shipped to Australia. Plugged it in and blew up the power board. Australia uses 240v power. Not sure if its only the power board which has been damaged but due to cost of the printer I feel its worth replacing the power supply and hope that this will solve the problem. Machine is not under warranty because it was shipped out of the US. Can anybody advise me on 
a) the likelihood that the damage is limited to the power board
b) if the ipf510 has fuse protection in which case I can just replace the fuse
c) best way to source a replacement powerboard and likely cost
Thanks

It's definitely not the speakers! I was using Skype and the buzzing got worse when I starting using the onboard webcam - it's definitely the power board connector. Last night I did some poking around and got the buzzing noise reduced, but I just did it by scotch taping this
over the connector. With that in place the sound works fine, the indicators are working, and the only sign that there's any problem at all is a crackle on start-up that goes away after a minute. Assuming it's stable and it stays functional, should I just be happy with that? I'm worried that taking it to a repair place would cost me a bunch of money I don't have for a fix that's basically no better than what I already did. I'm mostly just worried that the problem will come back now that I've got it working - those connectors seem really precarious.

  • Broken power board ZIF and buzzing noise

    Hey all,
    This is my first post on the forum! Thanks so much for providing such a welcoming atmosphere.
    I have a GE70 20E laptop that I disassembled recently to do some repairs on, and when I was putting it back together I snapped the little black plastic thing that holds the power board connector in place.
    I looked up some guides for the problem and eventually took the ZIF, replaced it as best I could, and held it down with electrical tape. The computer booted and everything was mostly fine. The power and fan indicators weren't lighting up, but I had a functional laptop. Eventually I started hearing little popping sounds coming from that area of the computer that I attributed to a speaker problem because it mostly happened when the volume was high. About a day ago the popping graduated to full-blown buzzing, which scared me.
    I went in and reapplied the electrical tape to the ZIF and power board connector and it fixed the power and fan indicators, but the popping remains. In light of that, three questions.
    1) Is the laptop safe to use?
    2) Is there a more permanent solution I should be trying?
    3) Failing that, does anyone have any tips on how to better the electrical tape fix?
    Thanks so much for your help!

  • POWER SUPPLY FOR MY CANON

    Hi there everyone
    I am looking forward to buy a power supply for my canon, do you know where I can find it or which one should I buy? Please recommend....thanks.

    Hi bebefle_89! Every model of camera uses a different power supply, so we will need to know the exact model of your camera to be able to answer that question accurately, but for EOS cameras you can get them here for PowerShot cameras you can get them here.

  • Data aquisition board installation,how to get the operation system know that the board exsist and to give it a number?

    I'm a green hand on hardware. This question is maybe kind of a silly quetsion.
    I already have a data acquisition board installed (built-in) and there is the corresponding program to control it.
    Now I need to install another board to the computer, and make the necessary Vi to control the new board. I'm wondering what should be the procedure like? HOW to get the computer know the new board. Should there be any driving program coming along with the hardware. Or the operation system should get to know the existing of the new hardware once it's installed( i mean plug in). Thank you for your kind reply!

    Hi Fenny,
    What is the model number of the second board? If your existing driver has support for this board (which I'm assuming is a NI board, and it's plug and play), your OS (which I'm assuming is Windows) should recognize it when you start up your computer after installation. You can find out the driver support for your board and OS from the link below. If the installation was successful, you should be able to see the new board in the Measurement and Automation Explorer (MAX) under "Devices and Interfaces". If you can see the board in MAX, there will be a device number assigned to the board, which you can use in your VI to communicate with it.
    If any of the above assumptions is incorrect, please provide some details (i.e. hardware used, driver you currently have installed, OS, and the application you'd like to use this new board for), and we can work from there.

  • New build with big bang x-power board. Any help welcome and appreciated.

    Started new build with big bang x-power board, i7 960 processor, 3 x 4gb mushkin cl7 ram and imation m-class 128gb solid state drive running Windows 7 ultimate x64. This particular SSD is probably just temporary. Since I don't have the SSD I really want (yet) and this 1 was given to me at no cost, by a friend who really hated it, I thought it would suit my current needs. The specs & reviews were not encouraging, but they were not exactly "terrible" either.
    Anyway, I was unable to install the OS on the Imation drive, while connected to a sata2 port. Got repeat bsod despite many variations in settings, including fail safe defaults. After clearing cmos and switching to a sata3 port, I got it to install no problem after putting settings back to cpu voltge: 1.35, dram voltage: 1.65, mode: AHCI and all others: default with only 1 RAM module seated.
    So... I think this may be a BIOS issue and was hoping someone could point me to the most recent BIOS version available for me to update my BBXP board. I believe v1.6 is what i'm looking for, unless my info is outdated. Since my plan is ultimately to run the OS from an SSD using a sata2 port, I definitely want to resolve this, and hopefully any other issues with the v1.0 BIOS that I just haven't encountered yet.

    Thanks again HU16E, and sorry for any confusion and/or lack of information. I'm guess you can tell i'm still new at this, but I'll try to do better with specifics in the future   -please forgive me.
    SSD = Solid State Drive. The brand of this particular solid state drive is "Imation" and the series is "M-Class." It is a sataII device that would not install the OS while connected to any of the sataII ports on the board. Initial attempt was made with all settings on auto. When that didn't work, I adjusted voltages because it seemes unstable with repeat freezes and restarts. The install seemed to start ok with adjusted voltages but still would not complete.
    I then moved the sataII drive to a sataIII (marvell) port, put all settings back on auto and the install went further (loaded files, copied files, expanded files, etc) but would froze several times during windows start up attempt. I then changed cpu & dram voltages back to the adjusted values I tried when the drive was connected to the sataII port and everything worked fine. Tested under load for 4 hours and no problems of any kind. Its still working now. I do however suspect I will have many more problems when I move the solid state back to a sataII port, or when I add my other Hard Disk Drives.
    BIOS version showed: 1.0.0 but i can check again to assure I didn't misread anything in my haste. If i'm mistaken, I will post the correction. Hope I answered everything the way you wanted & didn't just make matters worse and more confusing  lol.  thanks for the link as well, i'll check on it asap

  • Power supply for MSI 645 Ultra mother board

    I need to replace the power supply for a MSI 645 Ultra mother board. I've available a switching power supply Allied model DR-B500E, that doesn't have the -5V output (infact its 20 pin ATX power supply connector has no wire in pin 18).
    Can I use this power supply with the MSI 645 Ultra?
    Thanks in advance for any help.

    Hi, here I am. Sorry for delay but I had some problems with the PC (as NTLDR missing).
    However now is ok and I can confirm that it runs ok also with power supply without -5V output.
    Thanks a lot for the support and best wishes for Christmas and new year.

  • Power Requirements for Micro ATX Boards

    hey all,
    Are the power requirements for micro ATX boards the same as for ATX boards?
    I see micro ATX power supply rated at 250, 230, even 180 Watts and i'm wondering if that can keep a system stable.

    To my knowledge of Micro ATX PCB mobos + CPU and RAMs does not really tales up to the power requirements of an ATX PCB mobo + CPU and RAMs, so I think that 300watts will be a good bet.
    Power AMPs for individual rails as per:
    +3.3v = 20A approx.
    +5v = 28A approx.
    +12v = 16A approx.

    Since it says you have Mac OS X 10.7.4 in your profile information, it sounds like you have an Intel iMac, not a PowerPC iMac.  Is that correct?
    The procedure you describe is not exactly the right one for an Intel iMac.  You should follow this procedure to reset SMC (power management)

    When you do it, disconnect ALL peripheral devices from your computer, including your keyboard and mouse.  Connect the power cord only, and power it up that way, initially.
    Also, check the vents along the bottom edge of the iMac.  If they are clogged with dusk, it can block proper airflow, which can cause overheating, which can cause the fans to run high.  If the fans runs high immediately after starting up the iMac (when it is cold), this would not be the cause.
