Unable to use the cursor in the lined area. Once the cursor/pointer moves into the lined area, it is not visible/not usable.
Tapping on the back of the screen will sometimes reduce the contrast of the lines on the screen, making the screen look almost normal, but still unable to see or use pointer. When the laptop is plugged into an external monitor, the external monitor works well.
Sounds like a hardware problem to me. Is there anychance it is a software problem or virus? Any hints.
I can usually fix problems if it is fairly straightforward, like pulling out a broken part and replacing the new one, but beyond that, I stop.
This is Richard from Dell's Online Community Outreach group. I am very curious about your computer's LCD issue. You indicate that tapping the back of the LCD sometimes corrected the problem. Also, you mention that sometimes the problem would not occur until the computer had been on for 20 minutes. The behavior that you describe appears to be a physical problem with the LCD.
I would guess the issue is related to the inverter/LCD cable. However, it could be as simple as the LCD cable (22) not properly connecting to the video controller (6). One of these parts has probably come loose.
Notice in the graphic below that the cable connects at three points. The wide flat part of the cable (2), in the top right of the graphic, plugs into the LCD circuit controller board (3). I believe it is this part of the cable that needs to be reseated.
Please repost if you have any other question or information that could help solve this issue.
