Found out about this when one of our more recent Viewsonic monitor suddenly failed. Which was surprising since mine, a VP211b, is in service, always powered on even when the computer isn't, since 2006. 10 years without any problems. The story behind this, told by a colleague, is that a Chinese company has pirated only half of the plans to make capacitors. Their recipe left out the most important part. This is so much of a known problem that capacitor kits are available on Amazon (or Amasszone if we go by David McCandless' book "The Internet Now In Handy Book Form") for specific monitors. > Apparently these are *still* turning up in new equipment > and are extremely difficult to identify until they fail :( IMHO I don't think these faulty caps are still used today. They were quite precisely identified since then, I think the company went over, and people do not want to use them in their products for obvious reasons.
