Syncmaster 940bw buttons on front of monitor stoped working completely

Hi there,
You can try to disconnect VGA cable to see will the notification "no VGA signal" appear on screen. If so the problem could be with PC graphics, else it is power board problem bad caps.Thanks

Good Morning!
One thing that I have noticed when I change settings on my monitor is that sometimes it needs to be re-aligned. Thankfully this is very easy to do. There is a button on the bottom right of the screen that says "Auto".
Press this button and you should see the screen shift and become sharper.
If this does not work, you may want to change the monitor back to the default settings. You can do this by navigating through the menu: Press the Menu Button -> Select "Setup" from the on-screen menu -> And then separately select "Image Reset" and "Color Reset".
Please feel free to comment back if this does not solve your problem.
Thanks!

The screen went white can be due to failed T-CON board or failed power supply, I would inspect the power supply and the ribbon cable between the logic board and the LCD panel.

catchymob, If, with monitor OFF, push and hold "menu" button, and then push the "on/off" button. Still not reset? Try visit to Samsung web site. Hope this helps. 12fixlouie
Let me know with reply or comment from you.

Hi,

This usually means that one or more of the bulbs inside your monitor have gone

I have purchased them on eBay

Hi...there,
That's indicated your backlight inverter are busted. Need to replaced a new one or repaired it. To repaired look for a bad capacitors with a bulged on top of each caps. Not sure, just replaced all the caps... Have a nice weekend!

bring it to the service center for a check up

Could be a problem of front panel switches,some switches maybe leakyinternally short,Try replacement.

you will not be able to connect your speakers to your 940BW monitor, because the monitor itself does not have any audio in/outs (or speakers for that matter).

what you will need to do, is to hook up to your computer tower. usually, most soundcards will colour-code the 3.5mm jacks you need green (although I have seen cards that have black jacks as well).
