Question about Toshiba SD M1612 Internal DVD Drive
My toshiba sd m1612 started a few weeks ago not to play about half of my dvd's. All my dvd's are originals, bought in good stores.
When I insert any of these DVD 's the light on the front of the DVD blinks about ten times and then stops blinking and remains ON, indicating the DVD can't be read. Windows says that the DVD is either corupt or has a format not recognized by Windows.
I moved the player to another computer, went through installation, no change.
It's like the hardware of the player changed.
I tried a lens head cleaner -no change.
SOURCE: DVD not working

solution for CD-rom problem: turn CW the second little potentiometer with a tiny screwdriver, just a little and try to read a CD, if it doesnt work then try turn the potentiometer again. the same solution for DVD-rom but with the first potentiometer.
