The monitor thinks the "AUTO" button is depressed continuously. If water or something got into the button membrane and shorted it out it could cause this to happen. You would have to open up the screen to try and clean the buttons but that's not a guaranty.

    Most computer technicians should be comfortable enough to open the display to check it out. Most likely the buttons are all on a little board, could be very hard to find a replacement. If cleaning the buttons doesn't fix the problem then you will probably have to buy a new screen.

    Is it still under warranty?

    Warranty perioid was most likely a year.

    If it was under warranty, you could clean it up as best you could to make it look like it wasn't a liquid spill and try to get it replaced by Samsung.

    17" LCD monitors are going for about $150US these days.

When i turn on my lcd samsung syncmaster 540n it displayed a lot of colored vertical and horizontal video when i attached my cpu but it turns on when i powered my cpu

boot up in safe mode (press f8 while booting) If your monitor works now, you need to go the the samsung site and download the driver for you monitor. I assume windows 7, since that is where most of the monitor problem occur.

Samsung LCD have a Maximum of 3 to 5 color plan predesigned. To use them you need to click the required buttons in the bottom of the LCD. Select the one that fit best to you.
If you think nothing happening use manual.
Or try changing the video setting for your movie player.

I have a samsung syncmaster 204T monitor. Everything was fine until last night when i kept my system on standby for approx 5-6 hrs. Now whenever i start my system there is only a green led on front panel...

I just started having the same problem! The green light flashes, but the monitor is blank. None of the button work (menu, source, etc...) and nothing changes when I disconnect it from the computer. I was suspecting a bad graphics card at first, but now I'm thinking the monitor itself is bad?!

Funny monitor problem

If I were you I would invest in a new video display card. Sounds your card is intermittant, because the chances of a tube type display and a TFT display having the same problem is slim to none. LOL Good Luck Please dont forget to rate this thread
