Question about Samsung SyncMaster 204t 20.1" Flat Panel LCD Monitor
Monitor is black if I turn it off then on it comes up for a quick time then off. If I push source the same thing happens.
I had the same problem and fixed it replacing 2 820uF capacitors. Check-out the website recommended by Buddy. I purchase the parts at my local electronics parts supplier for $3.

Sounds like it might be getting too
hot and/or going bad. Not sure how to diagnose this without seeing it
myself. That is the best that I can do. Your video card could be
going bad. Try another video card on that monitor. This will be the
only way to decide if it is the card or monitor. Try it on another machine and
see what it does.

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.
