Got a same problem in 8250. Won't power up but it power on on jig (test box). Can flash. It can power up if BSI line shorted to ground but won't charge.

Any solution for this problem?? CCONT have changed.... I don't think so if it was Flash IC.

@MobileMafia
1)BSI goes to 2x10k Resistor Network located top right of ccont almost against the frame.
2)From opposite side of 10k resistor network it links to pin B3 of ccont.
U have broken track on either of these points. BRIDGE IT!
