Hi,
i'm still troubleshooting some noise in the audio system coming from a lcd-backlight inverter.
tried many many things and to make a long story short, when i "ungrounded" the shields, all noise was gone and everything seems to work just fine!!!
anyone have a clue where to look further?
is it a problem to let the shields "float"?
what i haven't had time to check any more today is wheter the shields remain grounded through an alternate path, which of course could explain part of the mystery. i highly doubt that would be the case though.
funny that the shields which should prevent problems actually cause some...
thanks for experience/tips/advice.
