    Yes it is.
    Soon, next days, whenever possible i hope to post the photos, so to close my problem and this unresolved open thread.

    Ooops, a typo error in the capacitor:
    JJ is 400V/100uF

  • Re: Benq FP71G+ Led Power Off

    Hello i'm here again.
    I've soldered the following components:
    J.J. capacitor 400V/100mF in place of Elite 450V/100uF
    Bridge rectifier KBL408 4A in place of 2LKPM06M 2A
    Fuse 2AT in place of 2.5AH

    But when i plug the pw, i get an eletric arc near the transformer T601 of the PWM Controller.
    What should i do next? My knowledge on feedback theory is gone from long time!
    Greetings!

    P.S. Can the capacitor be the problem? Usually this type is used in the amplifier stage of audio systems...

    Oh, i mean a web cam, not too expensive, i have no one.

    What do you think, would it suffice to take some photos of medium-high quality, especially with low or no blur?

    Otherwise i contact a friend with a real digital camera, so to have good photos.

    Benq FP71G+ Led Power Off

    Hi everyone,
    congratulations for this board, it's reach of good informations and tips.

    The monitor seems died: it is black and the power led is always off, when clicking on it.

    I've removed the "case" and on the power board i founded the greatest capacitor had a lead cutted and all corrupted by electrolyte. It is an unfaumous Elite 450V/100uF.

    I'll try to remove all the others Elite cap and some others element, trans, fet & transformers, and pico fuse, too.

    Next time i'll give you the results.
    Thank you for...
