Summary: I have owned this monitor for 4 years. It worked fine until recently, but now I have a problem with the monitor flickering. After hunting on the web I found that this was a common fault with the 204T. Due to faulty electrolytic capacitors - there is a fix that is easily found by searching on Google - but it does involve dis-assembling the monitor and removing the faulty capacitors and replacing them. It's not difficult, but not for the inexperienced either.
