Question about Samsung 215TW SyncMaster 21" LCD Monitor

1 Answer

Samsung SyncMaster 215tw screen goes black after about 1 sec.

I have a Samsung SyncMaster 215tw that the screen recently went "black" on. If I press any of the buttons on the monitor (menu, pip, etc.), the screen occasionally displays for about 1 second, then goes out again. I checked the connections, but since the menu doesn't even display, I think it is the monitor. Oddly enough, after pressing the menu button, there is a dialogue box that displays and states the monitor tested good, then it quickly disappears.

In the event my suspicions are not correct, here are the other things I've done. I've checked the cables to make sure they have not come loose. I didn't swap them out, as they are the only DVI cables I have. I rebooted the computer, and the screen displays for 1 sec when the boot loader displays the options for booting. I've also turned off the monitor via the switch on the back-side and underneath of the monitor where the power plug connects, and I completely removed the power chord also (based on a suggestion I read to another issue someone was having with this monitor). Nothing has worked thus far. My video card has only a DVI connection on it, so I was not able to connect another monitor to the computer to verify it is the monitor, as the 215tw is the only DVI monitor I own.

Thanks in advance for your help.

    a lot of people seem to be having issues with samsung 215tw screen flickers / going black at the moment - bought mine in march 07, and it's worked perfectly until now.... It seems to be something to do with the power, I think... because it's connected to how it responds to being booted up. And it seems to get better the longer you leave it. The flashing varies, and on mine it seems to be brighter on the right hand side of the screen.

I have the same problem its defenitly a problem with the lcd monitor not with the graphics card nor the pc. I hooked up the digital and afterwards the vga connection both had the same result. 1 s perfect screen all visible but than black. pushing the on/off or standby button again shortly 1s the display works than it blanks. Did the same test while connected to a dvd player via the composite video... same problem . Since the previous posts are that old and without a solution I guess there is no hope in getting it fixed.

Samsung syncmaster 215tw will only display faint blue screen-no images.


Hello,

Check for a failure of the capacitors on the power supply board. This is a common problem with these units and its a very easy repair. Here is a link to a repair guide for the SyncMaster 214T which uses the ame power supply board so the repair information would be the same for the 2 units.

When I play some games on my syncmaster 215tw, the screen goes black after 5 minutes. I have to reboot everytime to get the screen back on. The blue light flashes but i cant do nothing until i reboot....


that means your VGA is not big enough to run the game.This problem is not from the monitor but your system.I suggest an upgrade in your system to enhance better performance.

Samsung 215TW Monitor Flicker


Its the capacitors on the backlight power supply. Samsung installed crappy ones and they blow up after a year or two. Change out the caps and you're good to go
