Samsung LCD Monitor 740N line crawl problem

I own a Samsung LCD Monitor 740N for a month now. A week ago i suddenly came accross a problem with the display which never existed before. The screen showed up a line crawl over any image or video playback. I tried increasing the refresh rate from 60Hz to 75Hz and the crawl effect reduced quite a bit but is not gone yet. Please help in knowing the nature of problem, and if i can troubleshoot it on my own. Thanks, -Ankur

Thanks for the suggestion... but i detected the problem to be related to my TV Tuner card and the cable (for TV) attached to it. It created some kind of charge that needed to be earthed.. After removing the cable the problem seems to never recur. -Ankur

Two bright lines on my acer 17" lcd monitor


You have failed TFT driver in the T-CON board, in other word, nothing you can do to fix it without replacing the LCD panel.
