:( is there any test point left on the board to jumper on?

Man, just mount the new filters that you were doing & then give it a try & i'm bit sure it will work; there's a lot free pins with these filters & it's which mostly gets off board, just give it a try & you will not regret, i have faced such same problems & was as i told, B.R ...

virtue 10-22-2007 14:33

BE SENSIBLE, READ CAREFULLY SCHEMATIC U WILL FIND GOOD RESULT .IF U R NOT SATISFY WITH SCHEMATIC THEN U CAN CHECK IT BY URSELF BY REMOVUNG BOTH IC'S FROM THE BOARD AND THEN CHECK THE CONTINUITY FROM DISPLAY IC PRINTS TO THE DISPLAY CONNECTER .IF U FIND ANY CONNECTIVITY THEN POST UR RESULT HERE OTHERWISE CHECK BEFORE POSTING .HOPE U TAKE IT AS A POSTIVE .

a little ADVICE to a member means a BIG HELP to them...
