Tips for a great answer:
Hi hope your monitor issue has resolved. I would suspect the
problem is a hardware issue then a software setting. Since the monitor is over
three and half years old, if your monitor is a LCD with CCFL back light and had
been used almost every day, there may be 3 possible hardware issues. First is
the internal power supply, that can go wrong due to heating problem within the
monitor, this problem usually cause the monitor to display poor quality picture
and may show interference lines on screen prior failure. Secondly, it may be
the inverter that drives the back light, which may fail due to the safety
circuit kicks in, because it involves with high voltages. Thirdly it may be the
backlight itself, which is like most compact CCFL energy saving lamps that
flickers or turn itself off when it reaches the end of its service life. This problem
usually caused the monitor to show redness or yellowness images prior failure.
All of these can be resolved by qualified electronic repairers, all the best.
