Crying or Very sad Crying or Very sad We have this model set which has had a burn up on the main pcb(scan coil connector).Ihave repaired this,replaced the line op transistor(BU508AF),TVO6(BD680A),RV38(2.2OHMS,1W)and CD29(1MF,250V).
WHEN POWERED UP THE SET SHOWS A FULL SCREEN PICTURE DISPLACED TO THE RIGHT HAND SIDE,THE LINE OP TRANSISTOR THEN TURNS INTO A WIRE LINK!!! Crying or Very sad
