If you are saying that it powers off in a few seconds you most probably have a bad (internal) power supply.

Had same problem, Monitor first turn on, backlight off after couple of minutes, off/on backlight off after few seconds.
Solution cut J503.
Found voltage OVPT (IC501,7) quite low (1.6V) this is the reference value for VSEN the over voltage value. By cutting J503, OVPT becomes 4.5 volt but is not depending anymore on the current through the lamps. Instead of the link J503 I solder 2x 1N4148 diodes which makes the OVPT not go below 2,8 volt. (diodes in series, cathode points to nearest board edge)

I have the very same problem and I have no knowledge of the backlights of LCD panels. Is there any way to fix this yourself?

Samsung... | Answered on Oct 24, 2019

Good morning! Please review/check the set-up settings of your samsung flatscreen, best to refer it to the operations manual of the monitor which should be included when you bought it. best regards.

In the first instance I would check all connections. It could possibly be a wire not making proper contact. If that doesn't help, then look for the degauss or restore option on the monitor!

Check if the cable connecting your monitor from the video card is properly secure and not loose...
You can also try this... turn off your cpu..remove the cable from your video card.....Open the housing....remove your video card from your motherboard... clean the contact surface of the video card with moisten cloth.... after cleaning...connect the video card to the motherboard...attached the cable to your video card.. close the housing and try to boot again...

I hope that work.. if not my suggestion is you try your video card in other computer, try also the monitor to other computer.. to see which one failed.

Much appreciated if you rate this help.. thanks..

Capacitor was not the problem. Replace the monitor.

Samsung... | Answered on Dec 16, 2014

Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.

navigate below..on the "settings for all on power scheme",set all to never...so your monitor will not encounter that again..

Separate the wiring. Touching wires create cross-talk of signals. the pic will be clear immediately.

The back light tubes are probably exhausted. They can be replaced, or you could try a CCFL to LED back light conversion. eBay.com has some kits for doing that.

Google is your best friend : look for "hdmi splitter" or "hdmi switch" or for whatever protocol you wish to use.

Search for the Samsung website. you should find all of the info you need. Also windows 7 will find a driver for your monitor if you go to your device manager and click the device driver drop-down-window for your computer's video card. Check your Windows 7 updates in all programs on the 'start button'. What kind of problem are you having with the monitor? If only the driver update finding that isn't too difficult.
