Question about Samsung SyncMaster 245BW Monitor

Yellow and blue lines on 245BW

I have yellow and blue horizontal static lines across my screen. It doesn't happen when I first turn it on but when I open some windows. Especially anything with a photo on it. I've had the problem where the monitor will flash off and on as well. I'm using a Mac Pro desktop. That shouldn't matter. I took it back to the place where I purchased it and it worked fine when they plugged it in. I told them it didn't happen right away and never consistently. I have it set on the default resolution which I believe is the highest available. Any ideas?

Re: yellow and blue lines on 245BW

Well, my monitor is going back to samsung for a replacement unit. I plugged in my monitor in a bunch of other PCs and it's doing the same thing regarless of the PC or graphics card I use. Now I know it's the monitor. Getting it RMA'd with Samsung. Only had it for 18 days. Hope they send me a new one and not a refurb.

Try getting anything that may have a magnetic field away from the LCD (speakers, phones, any electronic product), does the problem persist?

Color noise suddenly appeared on screen, blacks show blue noise lighter colors yellow noise

You may have a poor connection with your LVDS cable which connects from the internal main board to the screen. This will either need to bre-seated or replaced.

What causes vertical lines on screen, some lines are thick and some are thin and appear over the task bar, they are across the entire screen.

They are static lines. They can be caused by a variety of reasons, damage to your monitor, damage to your vid card (perhaps it was got a little too hot?), ive seen this issue also with overclocked, try resetting to defaults if so. Also try reinstalling/updating your current display drivers. If you have an integreated video card it could be that your motherboard got hot and perhaps damaged it. If you have a spare vid card or something else you can hook up to try, and it still has the static lines, then it is your monitor for sure.

Syncmaster 245B Monitor Shivering horizontal lines

Which type of video connector are you using? VGA or DVI?

If you are using VGA, the horizontal line could be due to interference, like from an electric motor (fan) near the video cable.

Other thing to try is to change the refresh rate. In Windows XP: Control panel --> Display Properties --> Settings tab --> Advanced button --> Monitor tab --> Screen refresh rate. The default ot 60Hz for LCD monitors. Bump it up to 75Hz. That could give a clue to the problem or maybe even fix it.

Lines across screen

The screen you have is almost certainly on the way out. This type of fault is in the Horizontal Flyback section of the Monitor. Usually components fault or age and change value, these lines are normally "Turned Off" so ya can't see them, that "Turn Off" circuitry is going faulty.. it will only get worse. I suggest a new, or 2nd hand monitor as they are so cheap these days fixing CRT monitors can be cost prohibitive.
