The problem can be bad caps in the power supply, inverter circuits, or bad lamps. You need to open it up and see, report back what you find so we can help you further, see example of failed monitors due to bad caps, lamps here: http://s807.photobucket.com/home/budm/allalbums

How do I replace the inverter in a samsung syncmaster 930B?


Hello,

The 930B and the 710T use the same power supply/inverter boards. Below is a link to a repair guide for the 710T unit that should get you going in the right direction.

Hello, My Samsung 930B suddenly quit displaying and also no menus etc will display so I assume the back lighting function has failed. Is this a replaceable lamp or more likely a power supply issue? Any...


Look at the power supply caps first.
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 (they should be replaced in a set), 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

Check signal cable


Check if the monitor is not working by connecting this monitor to another computer.

If the monitor woks on another pc, then the pc is the issue and not the monitor.

If monitor doesnt work on the other pc, then it's the monitor that needs replacing.

I hope this helps you :)

SyncMaster 930B takes 20 minutes at least to become visable


IT SHOWS THAT THE PROBLEM IS IN THE POWER SUPPLY SECTION OF THE LCD. CHANGE THE CAPACITORS PLACED IN THE POWER SUPPLY SECTION. IT WILL WORK.
DONT FORGET TO VOTE.

Blinking blue light


You have to check if you can see the image on the screen or not after it went blank (Power on both CPU and monitor) by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. Like mine, I can see window image using flashlight and check lamps inside. Some of them were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.
Thank you
