I have a toshiba satellite m105 s3074 laptop. While it was being used, the screen went grey and I smelled something burnt. Afterwords, the screen was completely black. The computer works fine when connected to an external monitor. I just bought a new LCD cable and while replacing it, i noticed the original cable had melted. Once the new cable was connected, the lcd works but there is no picture, only black and grey vertical lines. Does anyone have any idea what the problem could be???
