Question about Samsung SyncMaster 204B (Silver, Black) 20.1 inch LCD Monitor

Samsung monitor picture clicks off after 2-5 seconds...

I have a Samsung flatscreen monitor (not sure of model, I am at work). I have had it only a little over a year. Yesterday a problem began. The monitor power stays on, but after viewing screen 2-5 seconds it clicks and goes black. To get a picture I have to turn it off and on again...to be able to view screen for another 2-5 seconds. Any suggestions on what this might be?

    Just to clarify, here is what is happening:
    Power stays on to the monitor, never shuts off. If I turn my monitor on, there is a beautiful display...then in just a few seconds you hear a click and my screen goes black. I have to turn off the monitor, turn it back on again and I have a picture once again for a split second and then a little click again and it goes black. Just like it would if I had it set on screensaver mode. Power stays on, but picture goes away...until it is turned off and on again. I have plugged in another monitor and it works fine, so I do know it is the actual monitor having an issue.

    Hello, It sounds like you have a monitor with a common problem. After a few years some LCD monitors
    will blow a power supply. The problem is caused by parts called
    capacitors overheating in the confined space of the monitor. If you are
    good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work
    fine. The capacitors do need to be installed with the correct + and -
    connections, note the stripe on the old one and insert the new one the
    same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping. I hope this helps, if so please rate my solution. Buddy Corporate Computer www.ccl-la.com Over 21 years of computer and printer support/repair

Yes, It sounds like the backlight inverter circuit is shutting down. No inverter power, no backlight. On some monitors the inverter circuit will shot circuit the power power supply which makes the power light flash on some it just kills the backlight. You can usually check with a flashlight. Hold the flashlight pointed at the screen and see if you can see any of the icons or background picture. If you can then it is the backlight circuit or backlight tubes, usually the circuit.

Samsung s42ax-yd01 - No picture / Sound OK problem


Hi,
If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
If your TV, flatscreen, or monitor is more than 5 years old it is more like to have suffered a component failure.
Take it to a repair shop.

Hello,

The picture board on your monitor is bad, since it goes off after few seconds and the power led or button is on, it means the picture board of your monitor has developed fault. It can be repaired, all you need to do is just to replace the picture board on the monitor, after replacing the picture board, you will see that the monitor will work fine, just as before.

Take care.
