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.

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.

Cheers.
