    Wondering if it is possible to "upgrade" the caps in my LCD monitor

    Good day
    I have a ProView monitor that was whistling, so some whiz (MD Willington) suggested I check the caps, which was the issue.

    Bads caps, 1000uf 25v

    My questions are; is it possible to put bigger better caps in rather than using the same size as I just took out?

    Is that worth it or asking for more problems than it is worth?

    If it is worth it then what would be a better size cap to use?

    I just read your post again, I am not sure what you meant by bigger. Physically larger? Higher Capacitance?

    In terms of physical size, as long as it fits, it's great!! The main constraint would probably be height, so watch out for that.

    In terms of capacitance, you can get away with going away from the original value a bit. However be wary of changing the capacitance too much, unless you study the electronic circuit, it is likely you do not know how changing the capacitance in the circuit will affect the operation of the monitor.

      Thanks Shadow
      Higher Capacitance is what I meant but when I posted I could not remember that big word!!!

      Thankfully you were able to interpret my vague question.

      I will take your advice and stick with the numbers on the caps I removed.

      Thanks again and I hope you have a great day!

        You can "upgrade" your caps, for example if the board is full of HERMEI caps or other crap-brand caps you can "upgrade" by removing them and putting on suitable Nichicon, United-Chemicon, Sanyo, Panasonic, Rubycon or SAMXON replacement caps in their place.
