Hello Techs
I finally got the fix for this set.
Solution= Resolder the T and U connector from main board to CRT ckt. Also
resolder CN001,CN002 on main board and PIP modules. Just to be safe i also
resolder C,F, CW connectors and IC601. Now the PIP is working and the A/V
jacks are functioning. Set have been on for the past 3 hours and still have
not act up. i`ll keep it on the testing bench a couple of days more just to
make sure she won`t act up again and return it to customer.
Thanks
Jose
