Neil,
This trace is located in the 12v standby, find IC U4102 (12v reg.) follow
pin 3 (output) this circuit trace should hook up to JW311, the other side of
JW311 should hook up to JC403, JC410, & JW308. The trace that was open was
between JC403 & JC411. As far as a grid #, I can't help you there, as the
schematic I was using was out of a Electronic Servicing Magazine.
Hope this helps!
