| Sony | KV1545R | INTERMITTENT RETRACE LINES IN PICTURE, REPLACED R722 | After the unit was energized, fine retrace lines wouldappear after 5 seconds and there was no control of brightness. G2voltage would not go low enough and G1 voltage was 125V DC instead of 30VDC. Wrong value resistor had been inserted in board (R722) i | ||
| Sony | KV1217 | INCORRECT TUNING OPERATION, REPLACED R078 | In program mode, pressing tune-up button would cause a changein address position only and could not program any channels. Also, nochannels could be put into or removed from memory. | ||
