Duff Lokfits respond to a little heat and a blast of freezer in confirming their status....... Slightly dud, badly dud or totally dud.
Have fun!!
I remember the Philips 210 TV chassis and you could go on a merry dance with them. You'd get a set on the bench with intermittent sound or vision and the customer saying that if you change channel the fault would clear. So the TV would be running away with the PCB exposed and the scope on and ready to go. When the fault appeared as soon as the scope probe was put on virtually any component in the vision or sound stages it would clear.
Eventually we only did a full blanket repair, 90% success rate that way and far less time involved.
