LCD Monitor Power Supply Modification

By on May 9, 2012

While browsing for LCD Monitor power supply spare parts i saw a website about how to modify ATX power supply into it. Although it was not nice to place behind the LCD Monitor, it works! You can do this modification on your own junk LCD Monitors but not on customer LCD Monitors unless if the customer agrees with your idea. Most of the LCD Monitors are running on 5v and 12 v, what he did was to defeat the original power supply and tapped the supply voltage from the ATX power supply output. Please click on the photo to visit the website.

Some repairers will use universal power supply or power supply from a DVD player to power up the LCD monitors. These power supply modules are smaller thus it can be placed inside the monitor which is more presentable. If you have modified these types of power supplies before we would like to hear your comment-thanks.

      Hi Arnel,

      Could it be the modified power supply output voltages too high?

    I am too done this trick before with my previous ibm lcd monitor, less expensive and you can find anywhere a junk psu, but sometimes it breakdown even with a higher watts psu. I have tried those old psu with only 150watts and it works.
    BTW thanks Jestine Yong, I have learned a lot with your page, very helpful specially for newbie tech like me.
    Thanks

      Hi Girish,

      Get at least a 80 watt power supply for the Monitor.

    Hi Jestine,

    Weve done this trick before with my partner in computer repair.
    We got this problem with two in one PC and LCD in one Hitachi
    brand from Japan. Since he's not that creative with this kind
    of problem coz he's expertise are more on software, we decided
    to replace the dead power supply with a regular/ordinary pc
    power supply. It works. Other than that, I also tried using
    the DVD power supply board in a sub woofer because the 12 VDC
    power supply is missing . I replace and redirect it inside.
    Yes it works again. Jestine keep up the good work.
    as well.
    12 volt and
