I was recently using my monitor and suddenly it just turned off and i can't power it on anymore even when i press the power button. i opened it up and i took some snap shots of the electronics or close-ups of the caps. there is cap that i saw that seems to be blown it has a black dot on it, but i am posting the images so that people with more experience can help me fix the situation if possible. thank you very much guys. attached are the images to the monitor.

There are at least two caps. bad, I circled them. there may be other problems as well, have you checked any voltages?
Try replacing those two and see if it fixes it.

Is this the same set you fixed in oct 2011 - I am surprised it has lasted so long. You were advised at the time that the caps you used were not good enough - did you go back and change them ALL as suggested by at least two experienced members, If not , you are now paying the price for that and you need to change them now with something decent like panasonic FR series though FM and even FC will do if you cant get the sizes in FR and FM.
Probably no point checking voltages until caps are replaced.

Don't change just the two bulged caps - change all of them. Why? Because suitable replacement caps are easiest found online (local stores usually only have "general purpose" caps, which are inadequate for this application and won't last long - hence it's not suggested to use them). So, if you are going to buy caps online and pay for shipping, you might as well get replacements for every capacitor in your monitor's power supply (except for the tiny ones and big 400V cap - that one usually does not need replacing).
Better yet, if you have more monitors like this one or other LCD monitors that have bad caps (hint: check model numbers with badcaps.net search engine), then get some extra caps.

You are not necessarily limited to Panasonic FC, FR, and FM, but they are nearly universal caps when it comes to monitors and are of very high quality, which is why selldoor usually suggests them.
Other choices that could work in LCD monitors are:
Rubycon ZL, ZLJ, ZLG, ZLK
Chemicon KY, KZE,
Nichicon PW, PS, PM, HE, HD, HV

**AVOID eBay for caps**
(Or if you are really set on buying caps from eBay, first post a link to the listing here before buying anything. There are just too many fakes and these fake caps don't last worth a squat either.)
