Can i finde the problem with this test?
Probably not. My guess is that the problem is somewhere in your setup, which this test cannot see.
Try something easy – connect guitar-TF-amp (nothing else) and see if you have the same problem. If you do, rotate the cables (use different ones at each position) and try again.
If you still have the problem, it's worth trying the self-test.
