    Benq FP19G+ turns on and off randomly

    Hello,

    Like the title says this monitor started to turn itself on and off randmly.
    It can work for 10 minutes or 30 minutes and then off, I can turn it on almost instantly.

    The problem was worse before replacing a bulged capacitor.

    Noticed that the main capacitor 450V/100uF was showing mostly 298V. Replaced it but the voltages stay the same.

    The weird stuff is that even if I turn it off, it will turn itself on sooner or later.

    It does the same without the backlights connected.

    Thank you so much for your help.

    Fixed it once, hope I can do that again.

      I actually started typing that you're probably wrong because it was ok for tens of minutes and then without touchig it it would turn itself off and on.

      Still, after replacing a random cap with a new one and turning it on but removing the buttons from the system it didn't do anything for quite some time.

      You might just be right. Thank you
