My syncmaster 732N powers up okay, goes black in 3 sec

My syncmaster 732N powers up okay, but after about 3 seconds the display goes black. Toggling the power restores it for 3 second as does toggling the display when connected to a laptop

    I opened it up and 3 of the 5 470uf caps had bulges on the top. I am waiting for the parts and I'll replace the three.

Look for caps with leaking/bulging top or have high ESR (Equivalent Series Resistance, need cap meter with ESR testing).
If you are going to DIY 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, 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/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

    You should replace the whole set of the secondary dc power supplies (5vdc and the 12~18vdc) caps so you do not have to open it up again. Make sure to use good caps such as PANASONIC FM or FC series wth low ESR rating from DIGIKEY.

My samsung syncmaster 732NW moniter doesn't gives the display. the ligth in the power button at right bottom corner only blinks, please help me!!


First place to look will be the power supply section, see if it has bad caps (bulging top), check to see if you have 12~18vdc feeding the inverter circuits, see example of failed SAMSUNG monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

Syncmaster 226CW showing picture only for a second + flickering


Hello,

Call and get the RMA for your monitor, the problem is in the power supply and it will only get worse. This is a common problem with LCD monitors after 2-3 years of use.

My acer al1916w displays the image for 3 seconds then goes black


Sounds like your video card. Check to make sure it's connected properly. If so, check to make sure it's properly seated to *********** board. The possible issue could be the card is connected enough to display the picture, but not enough to communicate with the monitor to stay on because it has an active feed. Best of luck fixing it

Monitor goes blank after 3 seconds -Samsung SyncMaster 920NW


Could be a power issue. If it doesn't show anything at all then that may be the case. It may also be the display itself. It would be a costly repair so you might be better off finding a new monitor.

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


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 17" LCD Blacks out


If you have a second monitor, you could use your computer until the monitor goes black... then plug in a replacement monitor. My guess is that one will display black too...

My gut feeling is that your VGA card is on the fritz... I'm not convinced it's your monitor. Do you have a replacement VGA card you can try? I'll bet that'll take care of the problem.

Samsung SyncMaster 192N loses picture; requires re-boot


Unfortunately, you two have two unrelated problems. CB, the monitor isn't asking you for the password, that's the computer itself going into hibernation, which shuts down the video output, hard drive, etc. You need to go into the power-save settings and either disable hibernate, or change the settings to your liking.

The other question about the screen staying on for 5 seconds... thats an inverter board problem.
