My samsung Syncmaster 940mw wont turn on when the pc is turned on

Every time i turn my pc on my syncmaster just stays in standby mode, and wont turn on.

I have lost my manual and don't know how to reset it to do this, as it used to come on
Its starting to wind me up having to turn it off & on constantly when using the computer.

    I do have the same problem with mine. Bought mine in february 2007, just called the Dutch service department of Samsung Electronics and told them about it.

    I will post the result below.

    Exactly the same power light flashes but wont turn on

  • Craigicus Feb 04, 2009

    This is the second time I've had the problem at startup.


    It starts out as an increasingly delayed struggle to start up -- with speaker pops that sound like a conneciton is being made.


    The status light flashes in single or double sets until the pop, then it starts.


    The first time my Samsung was under 36 mos, so I was able to go to Samsung web site and arrange that they ship me one with me returning the broken one in the same package -- excellent process!!


    Only now it is another year later, and my 36 months are up and the replacemeent is again doing the same thing.  Today I got it on by simply holding the on switch on for about three minutes.


    Check your warranty and see if you can return -- they have nice coverage!!!

    My problem also started with delayed start-up and speaker pops that lasts between 2 to 5 minutes before it will turn on.



    It got worst when it would not turn on unless I keep holding the power button,

    It died when it would no longer turn on even if I keep on holding the power button.

Hello,

That is a hell know problem with the 940MW tv/monitors. The power supply has failed because of parts called capacitors have shorted. If you can solder then you should be able to repair your monitor. Here is a link to the repair guide for this issue.

It turns off automatically and then I cant get it back on.


maurice_camp Read the post I did for other Samsung 940MW's by clicking on the name "SyncMaster" above. You too probably have a "switch-mode-power-supply" that has gone into shutdown mode because it has detected a fault with some other circuit or even itself.

I wasn't able to find a 940MW. I do see a 941MW and a 940NW.
The 941MW manual has some basic instructions on page 36.

The 940NW manual can be found here.

Good luck!

No sound when on pc mode


Check if your PC can play audio on some other speakers or headphone. If yes, check your monitor audio cable connections. If no something's wrong with your PC audio drivers. Try re-installing them or could be a hardware issue with your PC. Get it checked.
