Hello guys,
I bought a used M9 last week. The first thing I did when I arrived home was fixing the vastly known tactile switch failure that is prone to happen to these kind of units. Mine came with 2 of them broken. Since I have experience with electronics and soldering, this was an easy fix.
But my M9 also came with this strange problem on the display. It looks like dark lines that appears on the top of the screen and slowly goes down (I'll maka a video showing it), similarly to these "waves" Deano described.
Does anyone know how to fix it? I mean, I can live with it, the unit works great and the sound is perfect. But you know... It would be even better if I could fix the screen too.
