A common problem with monitors is the power supply. The electrolytic capacitors need to be replaced. The power supply is located at the back side of the monitor. The faulty capacitors are easily identified due to their shape (they become deformed after some time of use). It is common practice to replace all the electrolytic capacitors on the power supply (except the one or two big ones - high voltage capacitors). The cost of this repair is very low and it does worth to try (assuming you have soldering/desoldering skills).
