Anyone else having issue with their JJP GnR (LE) skill shot lanes?

Mine seems to false trigger all the time. I reseated all the cables, tried adjusting the position and tried cleaning the inserts.

When it is not mounted to the playfield it seems to work fine (trigger switches manually in my hand or with a ball).

Before I buy a new board, are these repairable?

Two other thoughts:

-Any chance other lights on the machine can cause false triggers?
-Is there a chance stray emf in the machine is causing this? Could a clamp on isolation magnet (like you get with expression lights) potentially fix the issue?

In the test menu it false triggers constantly. If I unscrew it from the playfield and hold it in my hand, the false triggers go away, appears to behave normally. I will be pissed if I spend over $500 on a replacement board that does not fix the issue, so I want to rule everything else out first.

Penny for your thoughts.

BMHOuze is right. The pinside forum is very active and very helpful. You tried the obvious things. I havent experienced it on mine at all.
