Samsung Monitor Flashes Analog / Digital and goes black

by Parttwo / August 15, 2009 6:19 AM PDT


My monitor, a Samsung Syncmaster 2443BW has been acting quite strange lately and i don't know what to do with it.

When i start up my pc the monitor goes on and shows the motherboard screen and bios information. After that the monitor flashes in the left upper corner: Analog / Digital and the screen goes totally black (before windows is started up). A few seconds later the blue led (power) goes flashing and the monitor turns off.

No matter what i do, i can't get the monitor to stay on, and what does this mean analog / digital?

I just reinstalled my OS (windows xp x64) and installed the driver from the samsung website (i selected digital on the setup). The pc worked fine on another monitor (before this, haven't checked with one after). The monitor also worked fine when first connecting it again with the pc, but after reboot i got and still get this...

I am running on a duo-core, windows xp x64, Ati Radeon HD 4870 X2 with drivers and ati catalyst completely up to date.

I would really appreciate any help or comments on this,

It sounds like a driver issue. You might try reverting the driver back to the previous state and see if you can get your picture back up. The monitor is working properly - to some degree - because it's able to show the BIOS. It sounds like the problem begins when the monitor loads past Windows and is unable to detect it at that point.

Also, you might want to check to make sure you're displaying in resolutions that the monitor can support.

I've seen this happen but the PC needed repair or another driver. Since that's the PC and not the display, the display maker rarely assists.

Samsung Monitor Flashes Analog/Digital

Samsung monitor always have problems with buttons at the right side of the monitor. For some reasons, button analog/digital always keep clicking. That way you got flashing analog/digital signal. You can do checking by click menu button and see they keep selecting by their own because this analog/digital button also used for selecting further option from menu. How to fix it? Tell them the actual problems.

Sorry but it appears you have told the forum what the problems are. Can you tell more about what the service folk told you to do next? It may shed some light on why you posted this information.

hi this is a reply from one guy with same problem from another forum , hope to help you:

"Hello i know this might be a dead thread but i'll post anyway Wink
My T220 had the exact same problems as the ones stated here, at first i thought that the problem was ath the capacitors of the psu ,i've replaced them but the same problem continued so i ordered a replacement psu for 20 euros hoping that it was a psu problem.After i installed the new psu the monitor worked for 1-2 minutes and then it started the same sh....t
BUT when i disconnected the small ribbon that goes from the side buttons to the small board behind the touch power button the monitor came alive and it;s been working ever since.
Hope this Might help someone Nick Lagis "

@Unknown1821, I did it right after I saw your post (disconnected the small ribbon from the touch power button, at the monitor) and my screen came alive too.
Thanks for sharing this info, I was close to desperation. Hope others can see it, thanks again.
