Flicking usually indicates components are starting to fail inside the monitor and / or an issue with the inverter.

When it's flickering does the picture stay exactly the same ( no distortion, just lighter) or does it get a little garbled with wavy lines?

    With my experience when dealing with lcd's 20" and larger most have two inverters. From what you're telling me I'm guessing one of them is faulty. You could try swapping them with each other to see if you get the same results but opposite, if so there's you answer.

    Here's what another expert did to resolve this problem:

    My samsung syncmaster
    225bw when turned on would have the back light stay on for about one
    second, then go black, with or without the signal cable attached to the computer. After your
    screen goes black, shine a flash light on the screen to see if you can
    see any images

    I repaired my monitor by replacing
    several bad electrolitic capacitors on the inverter board. These
    capacitors had broken bulging leaking vents on ther tops. There were two
    820uf 25v and one 330uf 25v electrolitic capacitors that had failed. I
    ordered from www.digikey.com Panasonic FC series
    low impedance electrolitic capacitors, However, the 820uf was not
    curently stocked and had to be backordered, so I got one 1000uf and one
    680uf to replace the two 820uf which were in parallel on the board.
    There were two 680uf 25v on my board which had not yet failed, so I also
    replaced them. On my monitor, the capacitors can not be longer than
    20mm, due to space limitations. These electrolitic capacitors have a
    life time between 1000 to
    5000 hours, so when you order get a few extra of the ones that went
    bad.

Flickering screen


Hello,

The flickering problem you have is caused by a failing power supply. There are parts called capacitors that are failing and causing the power supply board to put out pulsing voltages until it can stabilize. We have a repair guide posted on our web site at: http://www.ccl-la.com/blog/index.php/samsung-214t-repair/ If you can soldethen you should be able to do the repair yourself. If you don't want to do the repair we offer a repair service for this unit. You can get details for that service here: http://www.ccl-la.com/blog/index.php/service-request-form/

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

  7. Once the light starts flickering slowly turn off the power.
  8. Set the washer knob to the Green Reset Position and switch on the power.
  9. You will observe that the mode + Door Lock light flickers rapidly for a few seconds and then flickers slowly.

Screen flickers for about 20-30 seconds sporadically


Try looking at the LCD screen at a sharp angle to see if ghost-like video can be seen during the 'off' time of the flicker.  If video is still present even though not that visible, then either the backlight or its power supply are failing. The color problem could also be caused by a backlight lamp that is not ionizing completely.

Monitor flickring


  1. Flickering screen display

    Flickering on the screen can be caused by defective hardware in the computer or by improperly installed software, but it can also be caused by interference from external devices. The following examples describe situations in which your screen could start flickering:
    • Screen starts flickering because of interference caused by devices which generate magnetic fields, for instance:
      • a TV set
      • a laser printer
      • another monitor
      • fluorescent lights
      • hidden power lines
    • Apart from interference, an incorrect setting in your system CMOS setup can also cause flickering. On some systems it is possible to distinguish between interlaced and non-interlaced monitors. The setup of your system should always be colour non-interlaced.
    • Proximity to the monitor of fans, air-conditioning units or other devices with rotating motors.
    • The number of devices using power from the same electrical line. Are you overloading the plug?
    • Monitor placed on an unstable surface.
    • Improper video drivers, this is a software problem, see section B
    • An improperly configured or a defective video card.


  2. Reinstalling the video drivers

    1. Start the computer.
    2. Click Start, select Settings, and click Control Panel.
    3. Double-click the System icon.
    4. Select the Device Manager tab in the System Properties window.
    5. Make sure that View devices by type is selected and locate Display adapters and Monitor in the list.
    6. Click the plus sign (+) in front of both items to get a list of installed devices.
    7. You need to remove every device by highlighting it and clicking the Remove button and OK when the warning message appears.
    8. After doing so for both items, they should disappear from the list.
    9. Close the Device Manager by clicking OK, and you will return to the Control Panel.
    10. Double-click the Add New Hardware icon.
    11. Click Next, select Yes when it asks "Do you want Windows to search for your new hardware?", and click Next twice to start searching for new hardware.
    12. This will take a few minutes and, after it is finished, you will have to restart the computer. Windows 95 or higher will automatically set up the correct monitor and video drivers.
    13. If the screen is still flickering, click Start, select Settings, and click Control Panel.
    14. Double-click the Display icon and select the Refresh tab.
    15. Change the Monitor Refresh Rates until the flickering disappears.
    16. If the flickering remains, go to step C.


  3. Troubleshooting

    1. If it is possible, connect a different monitor to the computer. If the flickering disappears, it is a fair indication that the monitor is defective, otherwise go to the next step.
    2. Set up the computer and the monitor on a different place in your house. If the flickering disappears now, it is most likely an interference caused by something in the original location. Check for devices which can cause interference.
    3. If the flickering persists, check the setup of your system. If available in the setup, make sure that the option Monitor Type is configured as Colour Non-Interlaced.
