Suddenly aq thick vertical line is showing in my samsung 740N 15days old monitor. I have switched off and again on but the problem is there. however i have turned off and restarted the next day and it's not there. plz, somebody respond if there is any problem with it so that i can replace it or else is there any thing else?
Check vertical IC. .. resolder each pins...
There is nothing you can replace...... the driver matrix is bad..... the monitor is still under warranty.... return it for a new one...... opening the case will void the warranty......
I agree man pack back up that sucka and as fast as you can get it back to the store before they tell you you must have did something or you have to wait to have the set looked at!!
monitor is probably going bad. Try hooking up a different monitor up to the computer, one that you know works properly. If the same problem exists then its the video card, if the problem goes away then its the original monitor that is bad.
