    Re: Canon Adv C5045 - blank screen

    hi..

    can i ask what you have already tried and changed..im getting abit confused.

    as i understand you have changed

    main 1+2
    hdd
    power supply

    have you checked fuses on your ac driver pcb?
    dimms can also cause screen to no come on as no memory to start up boot.

    if it was HDD screen would still come on.either a background light or boot bar.

    this is caused by the all night power supply, weve seen it half a dozen times. No display just energy saver light (green) on

    I'm a newbie, but this sounds like what might be the problem with my C5255. What is the "all night power supply"?
