COULD BE THE LINE OUTPUT TRANSFORMER BUT I HAVE ALSO HAD THAT FAULT CAUSED BY THE FRAME OUTPUT IC AND S/C RECTIFIER DIODES ON THE SECONDARY OF THE PSU, S/C LINE OUTPUT TRANSISTOR, IF THE FRAME IC HAS GONE IT MAY ALSO HAVE DAMAGED THE MICRO PROCESSOR, BASICALLY THEY ARE A HORRIBLE TV TO WORK ON AND WE REFUSE FLAT TO REPAIR THEM ANYMORE AS THEY ALWAYS SEEM TO TURN INTO A NIGHTMARE. |
