Alberto,
Since you have a BDL168, you have the chance to test at a couple of places:
1st on the board. Using the tester on the header block, it will light/dark
the leds to show where the detectors think something exists.
2nd is looking in the sensor table. Here is the first place a detector shows
up in JMRI. Everything else watches the sensors.
3rd is the block table. It is driven from the sensors.
4th is the panel. It follows the blocks.
So start at the first stage and walk your way though. One note: faulty gaps
or mis-placed feeders will cause some weird detection issues now and then.
So where the problem exists may not be isolated to a single block but be an
interaction of more than one. Insuring they are isolated (remove a
connection at the BDL for example) should kill the track power at that, and
only, that block.
