solder a 50 ohm resistor on pins 5 & 6 of Novatek NT68F63LG chip...
good if you can DIY, best if a qualified technician do it for you..

SOURCE: i have samsung syncmaster 740nw how can i increase

you cannot set the resolution to 1024x768 but instead try 1280x720 or if you have graphics card try to set the resolution using its custom resolution by setting 1280x768.
It will surely solve your problem.

SOURCE: Samsung SyncMaster 730B LCD monitor isn't backlit at all

Most failure in LCD monitors are due to cheaply made caps being use. If you are going to DIY repair, please read below, or if you are going to have it fixed then at least you will know if you are being ripoff or not.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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.

Samsung Syncmaster 740NW vertical blue stripe


I've never opened one of these units, but I think you're right...a broken, cracked, or "cold solder joint"...had that problem on boards a lot of times. What has been assembled, should have a way of disassembling, unless the plastic was molded or glued after assembly, which is almost never the case, to my knowledge. Sometimes screws are hidden under labels, paper or metal plates, anywhere, really. If you can drop by a computer repair shop, you might be able to pick their brains about where the screws are, just depends on the person working there. Only other choice is to get the repair manual, but they're expensive and hard to locate, sometimes. Anyway, keep working on it, I think you'll figure it out!

I have syncmaster 740NW samsung lcd monitor i am using it for 2 years but today automatically its screen has been blurred even it is working slowly not clearly visible


If you are DIY'er go to Display in Control Panel and reset to default, this might work. If not, try a RESTORE POINT roughly before condition started.

Have you kept up with your computer MOT's

ie Defragging?

Blue vertical line appeared on samsung 740nw monitor


Make sure the monitor cable is secure on the computer and on the back of the monitor.
Try the monitor on a different computer.
If the lines are still there then contact Samsung for help.
If you are lucky your warranty is still active.

If this helps please vote for my solution.
