Broken analog pcb track

[Riccardok]

Hi all... I have a problem with my dso shell: during a measurement, I have heard a tick, and some smell from inside.
I have open it, and i saw some track broken. I attach a pict. Someone has a pict of a good pcb? Becouse I cant understand where the tracks goes...
And if it is 1 or 2 tracks...
Thanks in advance....
