    1. While some people have a library of photos of different monitors, there is no systematic list. That is why you attach pictures of your monitor using 'Manage Attachments'. Note links in my signature for hints on providing good pictures.

    2. What brand and series of cap did you use as replacements?

    3. The problem you are describing is 'Two Seconds To Black'. Common causes are bad capacitors, a problem with a CCFL (age related, or broken), the CCFL wiring (frayed or broken lead), or a bad transformer.

        Capxon is a known bad brand, considered 'replace on sight'. KSC is a known bad brand, not recommended. I have located the manufacturer's website, they have very little information available, so I have no idea if the caps you installed are low ESR types. General Purpose types will not work.

        I prefer Panasonic FM or FC series.
