Samsung SyncMaster 214T 21.3" LCD Monitor - Answered Questions & Fixed issues

https://www.manualslib.com/manual/792638/Samsung-214t.html?page=1

To determine if the LCD monitor or the video card/computer is faulty, connect the LCD monitor to a working computer. If the LCD monitor does not get a Windows image using this computer, then the LCD monitor could have a faulty inverter board or a faulty CCFL lamp.
Parts and service are available from LCD Parts, their WEB site is :-
www.lcdparts.net
If the LCD monitor is OK then the fault is with your computer.

Those aren't easy to find (if at all). Your best bet would be to ditch the original stand and get a VESA compatible mount or stand kit. You can usually get them for cheap on monoprice.com

Yes,A flickering screen indicates the power supply is not properly filtering the output power. This happens when the capacitors on the power board start failing. Here is a link to a repair guide that shows how to dis-assemble the unit and what to look for and replace on the power supply board. The repair guide also has videos showing the process.http://www.ccl-la.com/blog/index.php/samsung-214t-repair/I hope this helps, if so please rate my solution.BuddyMc

Hello,

Flashing or flickering is a common indication of failing capacitors in the power supply board. The fix is very simple and just requires replacing 5 capacitors on the board. They will need to be soldered. Here is a link to a repair guide for the Samsung 214T units. http://www.ccl-la.com/blog/index.php/samsung-214t-repair/

I hope this helps, if so please rate our solution.

See my tip here: http://www.fixya.com/support/r9352105-fix_colored_vertical_lines_lcd_display

either some capacitors were not replaced properly or you have nor replaced some of them.
The capacitor you need to replace will have a bulged top(swollen).

Try and change the refresh rate of your monitor by following these options--

1.) Right click on your desktop.
2.) Select Properties.
3.) Click on the Settings tab.
4.) Click on the Advanced button.
5.) Open up the Monitor tab.
6.) Manually increase the Screen Refresh Rate to 75Hz(60Hz if it is max), which is measured in Hertz

Please check out the complete procedure with pictures on this link---

Samsung 215TW Capacitor replacement

It does the same when attched to another PC?
Otherwise look for bad caps with domed tops first.
If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on: Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/ Post back what you see inside so we can guide you further and it will help out other people in the future also.

Ken, Unplugging the monitor for 48+ hours to disapate all electronics within the monitor may work. otherwise its probably a heat problem. When the monitor heats up something stops doing its job. Tim

Open the monitor, examine the circuit boards. Look for small components that look like small cans, these are capacitors. If you see any that look bulged on top, then your problem can probably be solved by replacing these. Check out the following sites;
