Mando,
If you had your iron too hot, these traces very easily lift..at the pads,
yet.
Ohn out the pads and look very closely for lifted pads.

This set when powered on,would try to start but go into shutdn.I
replaced the vertical ic TDA-9302h,D 409 (used nte 580) R420=1 ohm,and
C557 =100\50v lytic.Now when I power the tv on,tv comes on but has just
a line across screen (no vertical defflection).I have the manual for the
F8 chasis but not for this B8.They are different.The +13v and the -13V
at the ic are there.I had a known good used yoke,subbed it and made no
difference. Can someone with the B8 chasis manual send me a  print of
the vertical ckt so that I troubleshoot this problem .Any tips ir idea's
would also be apreciated. Thanks.

PS  I made sure that the traces to the ic are ok.I have seen some come
apart when unsoldering the ic.Also the traces to D409.
