Unsoldering is the only way to UN-mount capacitors the board needs to be out of the casing. a solder iron and some electronic solder wire can be bought at radio shack or any other electronics store.
procedures are all over the internet

My proview monitor stays on for 10 sec then goes black. but i can faintly see my page.


This indicates an inverter board failure, caused by bad capacitors that sometimes bulge at the top showing that they are open, an attempt can be made to repair or replace the board.

Sence yesterday morning when i turn on my Proview PL926WBi 19" LCD the power light flash's for a while with a black screen then come's on and work's fine. what is wrong with it??


It may have dying power supply due to bad DC filter caps, it will more likely to get worst and more components inside will be damaged.<br /> <span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">If you are going to DIY and have proper tools and know safety precaution then please read on:</span><br /> <span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: <a href="http://s807.photobucket.com/home/budm/allalbums">http://s807.photobucket.com/home/budm/allalbums</a></span><br /> <span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Post back what you see inside so we can guide you further and it will help out other people in the future also.</span><br /> <span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"><a href="http://en.wikipedia.org/wiki/Capacitor_plague">http://en.wikipedia.org/wiki/Capacitor_plague</a></span><br /> <span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Capacitors kit: <a href="http://lcdalternatives.auctivacommerce.com/">http://lcdalternatives.auctivacommerce.com/</a> he can make you a set of caps for you.</span><br /> <span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial; mso-fareast-font-family: 'Times New Roman'; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA"><a href="http://www.badcaps.net/">http://www.badcaps.net</a></span>

On modern capacitors 2005 or up the capacitors can go bad and not even bulge at the top. I replaced a few in my moms flap panel monitor and found out that there were more that were bad and they didn't show any signs of damage but put your finger on one of those suckers and it burns like a smoking gun.

have a look at the board open up the monitor and remove the boards and you have to look for doomed or colored caps, they will be obvious compared to the good flat caps on the board. replacing these will most likely repair your issues.

I did it just because the higher voltage caps would give a lower heat dissipation thus leading to a longer life this time around.

thers Sounds like the problem I'm having /had exactly. When I opened the case I found that like others the 470mf capacitors on the power board had gone bad. (See the post from Delphiuser)

The capacitors are probably from a Chinese company called Xandu and I'm currently looking for a replacement capacitor to fit the circuit. Its a 470 mf cap with a 25 volt rating .
