20 Most Recent Samsung 931BF 17" LCD Monitor Questions & Answers


I have the same monitor, and twice I've experienced this exact problem. In my case, the video connectors have relaxed. If I wiggle the cable, I can make it better or worse, so it's time to disconnect, reseat. I don't know if it will work for you, but it's free!

just unplug the monitor and replug it after a few seconds, My streaks disappeared, It works like the degaussing button which got rid of built up static.

Blue tint/cast over the whole screen can eb from video cable is not properly seated/bent pin, or in the Video card. I would try checking and reseating the video cable first, also try it on another PC to find out if your PC has the problem or not.

Look for bad caps first, then the inverter circuits.
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

More likely to have power supply problem when it does strange things.
Very common problem with all LCD monitors. Look for caps with leaking/bulging tops.
See failed SAMSUNG and other brands here to get some idea what to look for inside if you are going to DIY repair.

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!
