Samsung Monitor 2232BW

Check the cable going into the back of your monitor and the cable from your monitor into your computer, one of them is most likely loose.

Monitor has been successfully broken with fall.

Hi , it seems you are experimenting a light engine problem.Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine. Have a blessed one!

It is probably the main total assy needs to be replaced.

You have a completely different problem. The screen voltage for the blue picture tube is slightly too high on your set. This will put fine lines in the background of the picture, called retrace lines. This is very common and easy to correct. Remove the front speaker cover and the access panel behind it. Look inside and you will see a black box with six controls, each control having a little white glue on it. This is the Focus/Screen block. Three controls are labeled Focus and three are labeled Screen. The screen control in the center is for green but I am not sure if the screen control on the left or right is for blue for your model. With the TV on, set it to VIDEO 1 but do not connect anything to the VIDEO 1 jacks. This will produce a pure dark picture, showing any faint lines in the background. Choose one of the screen controls and increase (turn clockwise) it slightly. If the blue lines do not get brighter it means you are turning the red screen control, so put it back where it was and choose the other screen control. When you find the blue screen control, decrease (turn counter-clockwise) it until just when the blue lines are gone. If you want you can check that the red and green screen controls are set to just below the point where their faint lines are visible. When done, replace the panels and your picture will be back to perfect.

MikeNJ1964 was exactly right! I have a Sony KP-65WV600 that had horizontal green lines that showed when the picture was darker. I had to remove 3 screws on the right and left side of the tv holding in the speakers...carefully pop out the middle panel from the clips holding it in....remove 4 screws from the cardboard in the middle and remove the cardboard. I then saw the six screws. The adjustment screws were the three below. I turned the middle screw until the lines dissapeared. I tried the left screw and blue lines appeared which I then adjusted away.
THANKS a bunch. SAVED me money!!!

line driver element defective. no repair possible, to my knowledge. replace LCD or ignore line.

sounds like you need a replacement drum as it sounds like it is faulty, this is a replacable part and needs to ber replaced from time to time, this is a common symptom of this fault

This is a common problem with LCD screens. It is pixel line damage and the screen is permanently damaged and is not repairable. It will probably get worse. The only answer is to replace it

Sounds like a bad connection on a ribbon cable or plug comming or going to the LCD display. This is something you should not try to fix as these circuits are very very fradgile and you can easily break or tear a ribbon cable . Call the manufacturer to get a tech to assit you. Good Luck
