Toshiba Satellite M35X-S149 laptop video problem.

Laptop problem: Toshiba Satellite M35X-S149 has no video. The customer complained that the laptop LCD video just disappeared without any reason. When he starts the laptop the screen lights but there in no data on it.

Laptop diagnostics: I started the laptop normally and LED showed normal activity. The hard drive started spinning. The LCD screen lighted but it was solid white color without any data on it.

Laptop repair process: when I get a laptop for repair with video problem, I always start with checking an external video. I connected the laptop to the external CRT monitor and started the laptop. The external video was fine and the laptop booted to Windows without any problem. Usually, if the external video is fine, the system board is good and the problem is in the LCD itself, in the video cable or in a bad connection between the LCD and the system board. On the next step, I removed the keyboard and reseated the display video cable on the system board, but it didn't fix the problem. The laptop still booted without any data on the screen. Finally, I opened up the LCD display and found that the video cable connector on the back of the LCD screen was half way out. I reseated the connector and restarted the laptop. This time the laptop started normally and I got internal video. So, if your laptop starts with solid white screen without any data on it, try to reseat the video cable connector on the back of the LCD screen.
