    Proview 19" LCD monitor pl926wbi bad caps first time

    Hello all. This is my first time replacing capacitors and I just wanted to be reassured I was going about it correctly. I have a pl926wbi Proview monitor and when I turn it on the on/off light blinks with no display. If I leave it on after some time the display will eventually show up, seems to need to be warmed up. This got me to research the problem, take apart my monitor and decide I need to replace some bulged capacitors that are spewing electrolyte.
    I found six xunda 470uf25v capacitors on it four of which were bulged. I found some 470uF 25V High Temp Radial Capacitors at http://www.parts-express.com/pe/show...umber=020-1736 I wanted to make sure if I order these that they will appropriately replace my faulty originals. I have attached a picture of these capacitors in question. I see other capacitors on the board, I was wondering also if I should order and replace these even though they do not appear to be bulging? Thanks for any help.

    With the exception of the large 450V cap, replace ALL the the smaller caps. Many members suggest using Panaasonic FM or FC caps from digikey.com. Use the instructions below:


    Here's the best way to order from digikey:

    1) Go to digikey.com

    2) In the "parts search" window type: panasonic fm and select "GO" button

    3) Under the Capacitor heading select "Aluminum"

    4) The first two columns you see are capacitance and voltage. Highlight the value and voltage with your mouse and select the "Apply Filters" button

    5) You'll see several selections available. Here's what to look for:


    a) Look at the quantity available and minimum purchase. If "0" are available, then there's none to purchase. Some selections require a minumum purchase of a 1000 units, which you also don't want. I think you get the picture.

    b) height and diameter. Measure the original caps and compare to what's listed.


    6) If your value is out of stock, go back to the beginning and type in "panasonic fc" and go through the same process

    7) During the checkout process select USPS First Class shipping, since this will give the best ship rate.

      Forum members here like brands like Panasonic, United Chemicon, and Rubycon. If you live in the USA, you can follow PlainBill's instructions to order Panasonic FM capacitors (FC is 2nd choice).

      https://www.badcaps.net/forum/showpo...33&postcount=2

      Or you can order caps from this list ...

      Forum members will recommend that you replace all the capacitors except the biggest one which rarely, but not never fails.

      Capacitors die from age, heat, and shoddy build quality. Capacitors DO NOT have to be visibly bloated in order to bad. They can be out of tolerance uF (a 1000uF measures 20uF) and/or have high ESR (ohm).
